Metric sockets are necessary if you intend to operate on any imported vehicles (Honda, Toyota, Kia, Hyundai, Subaru, Mitsubishi, Nissan, etc.). 9 out of 10 times, SAE tools are never used when working on imported autos; only metric sockets are required.
However, you will probably require both SAE and metric sockets if you are just operating on domestic vehicles. According to my observation, all brands from Japan, Korea, and Germany are metric. Even worse, certain US brands employed a mix of metric and SAE throughout specific years. Some US brands are entirely SAE or entirely metric.
It’s awful, I know. I hope the businesses could come to an agreement and utilize the same fastening system. Even on the same vehicle, some vehicles and trucks used both metric and SAE fasteners. The body may have been put together in the USA, but the engine may have been imported from elsewhere (and hence metric) (SAE bolts). They sometimes cause real butt agony.
If you’re like me, you spend the majority of your time working on imported autos. I love working on foreign automobiles in general because I am partial to them. As a result, 90% of my tools are metric.
I strongly advise starting with metric sizes for your socket sets and adding any SAE sizes you discover along the way. Metric sockets are unquestionably more in demand in 2018 than SAE sizes, but it really all depends on what you’re focusing on or what kind of automobile you have.

Which Wrench or Socket Do I Need: SAE vs. Metric?
While other countries utilize metric tools, the vast majority of wrenches and fasteners in the United States are SAE. But in today’s world, you can very well require a set of both. This is especially true if you are working on your imported car with your wrenches. Here are a few techniques to determine SAE fasteners from from their metric equivalents.
At first impression, metric and SAE wrenches have similar appearances. Both types of systems use fasteners with 6-sided heads that can be accessed with open-end, boxed, or socket wrenches. The measurement systems used by SAE and metric wrenches, however, are completely different. While SAE employs inches and fractions to communicate measurements, metric tools use millimeters.
Which socket and wrench should you purchase, then? Are these instruments also interchangeable? We’ll share some useful information with you regarding SAE and metric wrenches and which tool you’ll require for your task.
Use SAE or metric in American automobiles?
As it develops more and more international car platforms, the North American automotive industry is moving toward a metric wire standard. On new product lines, Chrysler, Ford, and General Motors will start switching to ISO 6722 wire. However, SAE J1128 wire will continue to be used in all carryover vehicles.
When did vehicles convert to metric?
General Motors sent letters informing its 47,000 suppliers of the switch to the metric system in 1973. The business organized a conference with 600 of its nut and bolt suppliers six months later to discuss the thread system it had chosen. The end outcome was the largely metric Chevette.
Does Honda use metric or SAE?
You go to the hardware shop to buy a replacement because you have a damaged bolt—it might be stripped or bent. There you are, surrounded by various little hardware such as nuts, washers, and bolts. Which one do you actually need? Finding the appropriate bolt would be much simpler if you had even a basic understanding of how bolt sizes are translated. The majority of nations, excluding the US, classify hardware using the metric system, hence your Honda is built using metric hardware. Your search has just been condensed to a single aisle. The majority of metric bolts in a hardware store have some kind of stamping on them. For instance, a normal U.S.-grade bolt might have three or five dashed lines on its face, whereas a metric bolt might have a “8.8” or a “10.9” imprinted on its head. If you can’t see either, the bolt is low-grade and has a low tensile strength, which means it can only withstand a little amount of force before snapping. When upgrading hardware on your Honda, you should be extremely concerned with a bolt’s tensile strength, often known as its “grade.” The majority of Honda equipment is metric grade 10.9 or better.
How To Know Your Bolts: Look to the numbers to determine the size of your bolts. They serve as a means of identification for manufacturers. Metric ones will resemble the following:
1. The letter “M” indicates that the bolt is metric, and the number “3” indicates that the bolt’s outer diameter is 3 mm. The bolt’s threaded part, not the head where you would place your wrench, is where the outer (also known as major) diameter measurement is taken.
2. The second placeholder, in this instance “0.4,” denotes the separation between threads. It can be measured from peak to peak or from valley to valley; in this case, it is 0.4 mm per thread, meaning there is a high spot and a low area every 0.4 mm. This measurement is also referred to as the “thread pitch.”
3. The last figure is the bolt’s length, which is calculated by measuring the bolt from the bottom of the head to the end of its threads. It is 10 mm long in the case of the sample bolt.
More advice: A thread gauge can assist you assess the thread pitch and size of an unknown bolt. Try putting your bolt into a known matching thread, such as an old nut you have lying around, if no such tool is available. Stop right away if you encounter resistance to prevent stripping the threads.
Set two bolts side by side and in opposing directions to see if they are the same. They have the same thread pitch if the threads mesh. This is another easy method to determine the length.
You can locate a wrench that tightly fits around the bolt’s threads and use it to measure the main diameter.
Most bolts have right-handed threads, which means that in order to tighten or remove them, you must turn them in the other direction. “Righty-tighty” and “Lefty-loosey” should always be kept in mind.
metric or standard, which is preferable?
Measurements in Metric The preferred fastener measurement across the globe is metric. Metric measures, which are based on millimeters, are a precise depiction of the diameter of the fastener head and are more accurate than fractions of an inch. Metric bolts have been utilized in imported autos for more than 30 years.
Are mechanics metric users?
Metric bolts have become a hot topic among vehicle repair technicians and manufacturers since since Ford’s Pinto engine and Cadillac’s 8.2 L Eldorado engine were introduced in the 1970s. Metric bolts are now preferred by the majority of domestic autos over SAE inch-sized bolts.
Hyundai employs SAE?
The Hyundai Sonata uses SAE 5W-20 or SAE 5W-30 motor oil. Sonata owners are advised by Hyundai to use synthetic motor oil. It’s reasonably priced and keeps your automobile running for a lot longer than regular oil would.
Which brand of oil does Hyundai use?
When Hyundai’s automobiles leave the assembly line, Quaker State is also the company that supplies the original motor oil. Quaker State, a pioneer in consumer automotive goods and vehicle maintenance for more than 80 years, is built on confidence and giving its consumers the best value, just like Hyundai.
How is SAE translated into metric?
- First, change the fraction to a decimal. The inch fraction must first be changed to a decimal.
- Convert to millimeters in step two. The inch decimal will now be multiplied by 25.4 to become a millimeter.
Uses Hyundai synthetic motor oil?

How frequently is an oil change advised by Hyundai?
Every 7,500 to 10,000 miles on average, a Hyundai oil change is advised; nevertheless, it is crucial to check your owner’s manual to be sure.
Does Hyundai advise using synthetic motor oil?
While conventional oil only lasts between 3,000 and 5,000 miles before it needs to be replenished, synthetic oil can last up to 10,000 miles before it needs to be changed. We absolutely recommend synthetic oil for the Hyundai Elantra because it offers drivers many more advantages than conventional oil does.
Can I replace the 5w20 in my Hyundai with 5w30?
It is generally not advised to substitute 5w30 oil (or any other oil weight) for 5w20 oil because even a small viscosity change has the potential to harm your engine.
Because 5w20 oil was precisely considered when your engine was created, all of the parts that come into contact with it must be a specific viscosity after the engine reaches operating temperature, or 212a.
5w20 oil will have a lower viscosity than 5w30 oil at this temperature; it will flow considerably more easily and with less resistance. When 5w30 is used in place of 5w20, the engine will experience increased oil resistance once it reaches working temperature, which the engine is not built to manage.
If you use 5w30 oil instead of 5w20 when it is not advised or permitted by your owner’s manual, it could violate the powertrain warranty on your car, impair engine performance, and ultimately harm your engine.

Do SAE sockets fit metric sockets?
Can SAE fasteners be used with Metric sockets or Metric fasteners be used with SAE sockets? Yes, some sockets can be used with both metric and SAE sizes. However, you must exercise caution because they are frequently not identical, and using an SAE socket on a metric bolt or vice versa can strip a bolt.
Is SAE a benchmark?
The engineering industry’s professional association and standards-development body, SAE International, has a particular focus on the transportation sector, including the automotive, aerospace, and commercial vehicle industries. The Society of Automotive Engineers was the name under which the organization was first founded.
The SAE offices in the US are located in Warrendale, Pennsylvania, and Troy, Michigan. Through significant efforts in standards, STEM (science, technology, engineering, and mathematics) promotion, professional development, and certification, the organization provides services to 138,000 individual members globally. Additionally, SAE organizes seminars, publishes materials, and funds collegiate design competitions.
The aerospace industry’s standards and SAE’s ratings of vehicle horsepower are its two most well-known accomplishments. Although none of their guidelines or criteria are legally obligatory, businesses and government organizations normally abide by them.
Henry Ford, Andrew L. Riker, Edward Birdsall, and John Wilkinson created SAE in 1905. Many well-known people, including Thomas Edison, Charles Kettering, Glenn Martin, and Orville Wright, provided input to the organization. The term “automotive” was first used by Elmer Sperry, a former SAE member, and comes from the Greek autos, which means “self,” and Latin

What are the purposes of SAE sockets?
Ratchet sockets allow you to easily and rapidly make adjustments. The kind of socket you require will depend on the task at hand. Here is a list of the most typical socket types you will encounter and when you will probably utilize them:
- SAE sockets: For use on automobiles developed in America, SAE (Society of Automotive Engineers) sockets are produced. Inches and fractions in the imperial system are used to measure socket sizes. Sockets in the SAE sizes of 3/8 in., 5/8 in., and 11/16 in. are some of the more popular sizes.
- Metric sockets: Metric socket sizes are specified in millimeters, making them perfect for use with foreign automobiles. 8 mm, 10 mm, and 14 mm sockets are the most popular sizes.
- Bit sockets for Torx(r) screws: The sockets are equipped with star-shaped bits. The capital “T” and a number are used to denote the sizes of Torx bit sockets. The most popular socket sizes for Torx screws are T6, T8, T10, T15, T20, T25, and T30. The socket sizes vary from T1 to T100. Wherever additional torque and power are required, Torx screw sockets are the best choice.
- Impact sockets: Impact sockets are made to be used with impact wrenches and are perfect for heavy-duty applications like removing rusty, tough, or aged bolts from machinery or automobiles. There are impact socket sizes in both metric and SAE.
- Driver sockets, also known as bit sockets, are used with a ratchet handle to tighten and loosen screws. For nearly all screw types, including Phillips, flat head, and hex, driver sockets are available.
- The bolt you’re working on can pass through the socket and ratchet with the help of pass-through sockets. For lengthy, threaded bolts found in equipment, electronics, and automobiles, this capability may be useful.
- Spark plug sockets: Designed specifically for changing spark plugs, spark plug sockets simplify this car maintenance task.
