Do You Need Both SAE And Metric?

Do cars use metric or standard?

As with all wrenches, you have the choice between U.S., also known as standard, or metric sizes.

American cars are assembled with nuts and bolts that use standard measurements while foreign cars almost exclusively use metric measurements..

Is 3/8 and 10mm the same?

10mm = just over 3/8 inch. 11mm = almost 7/16 inch.

Does Ford use SAE or metric?

Ford has a couple metric 12 point fasteners on their drive shafts as well. American cars haven’t been SAE in a long time. So what uses SAE?

What are the SAE socket sizes?

Course Tool ListSix Point Standard Sockets (5/32, 3/16, 7/32, 1/4, 9/32, 5/16, 11/32, 3/8, 7/16, 1/2)Six Point Metric Sockets (4, 5, 6, 7, 8, 9, 10, 11, 12, 13)Drive Tools (1/4”):

How do I know if my bolts are standard or metric?

The metric screw thread is identified by the capital letter M, followed by the nominal diameter. Metric threads are measured by the distance between two adjacent threads in millimeters (pitch). Threads on a standard (inch based) fastener are measured by counting the number of threads per inch.

Are metric and SAE the same?

While the majority of bolt-type fasteners used in the United States conform to one or the other measurement scale, the difference between SAE and metric fasteners (and their corresponding sockets) is as profound as the difference between yards and meters: They are almost the same, but not quite.

Is SAE and Imperial the same?

Imperial is a complete measurement system, not a fastener spec. … SAE (Society of Automotove Engineers) tool and fastener measurements are imperial, and are referred to as SAE to differentiate those sizes from nominally metric sizes.

What is better metric or standard?

Because it’s so much simpler and easier to use. The metric system is an improvement over the English system in three major points: One unit of measurement for each physical quantity. No matter from which other quantities of the SI system derived, yields always the same unit.

What’s the difference between metric and standard sockets?

How do metric and standard sockets differ? … Metric socket wrenches fit fasteners where that nominal length is a round number of millimeters (8mm, 10mm, 15mm). “Standard” (often “inch” or “SAE”) socket wrenches fit fasteners where that nominal length is a round fraction of an inch (1/4″, 1/2″, 13/16″).

How do you tell if a bolt is SAE or metric?

Metric and SAE fasteners are measured differently and with different vocabulary. SAE nuts, bolts and screws are measured by their thread count, or TPI (threads per inch) and their length. Metric fasteners are measured by length and pitch, or the distance between threads.

When did GM switch to metric?

1973When General Motors decided to go metric in 1973, letters announcing the move were sent to its 47,000 suppliers.

What year did Ford switch to metric?
