Sign In New To Mechanics & Need Help To Learn SAE Tools!!! I am thinking on taking mechanics courses in the fall but i know little or nothing about tools. The metric tools seemed easier to learn and i know a small amount about them, but SAE tools are throwing me for a loop. I was never good at math let alone fractions. any advise on learning them? any books/sites or videos i can watch or read to learn them? I have seared a lot and cannot find a good resource for learning SAE.

Metric to me would be great if they skipped odd #s as by eye I don't like guessing by ONE mm sizes nor sets that don't include 16 or 18mm commonly for non pro and more expensive stuff. You can't fake those sizes. SAE prior to the English sizes like 11/64th generally you can look and know. Start with common by eye. 5/16ths (same as 8mm) on up. You'll find 3/8th common looks like 10mm at a glance and so on. Know which sizes are the same in either metric or SAE. Just a couple and helps to know. 3/4" = 19mm. Wheel lugs with 3/4" and chrome covers that rust or fall of an 18mm grabs those perfectly. Suks with a whole generation of vehicles (American) that used both all over same car. On those look. If a fastener is to an older engine (all iron) a bolt into it is SAE. Accessories on it probably metric as well as body nuts and bolts. Watch out for 15mm and 9/16th as at a glance real close but don't work on each other same as 13mm and 1/2". More recent odd ball # is 7/32nds = 5.5mm (how nice to fractionalize a millimeter) if you run into that. Here and there square things. Try 12 point on some and get a sure grip when not critical especially. Yes there are sets of 8 point sockets that are for square things. Most outdated now to mix both on the same vehicle. Some of that vintage the metric was colored differently so you knew to look for a metric not SAE size. Mostly done but still grab from both sizes if close by eye and it matters especially some not so much automotive junk Allen heads but some for brakes and throw in Torx (star shaped stuff) as well. Sells a lot of tools doesn't it? T GC User Jul 18, 2014, 6:09 AM Post #3 of 4 (1557 views) Re: New To Mechanics & Need Help To Learn SAE Tools!!! Sign In What are you wanting to learn? The sizes? I recommend buying a set and using them a bit. They will be in order and will help. Also remember that they are split in half every step down in fraction. And that the top number of the fraction is going to be an odd number. If you have an even number on top, you need to split the fraction in half. 1/2=2/4=4/8=8/16=16/32 so if you have a 5/16 that is too small, the next 16th up would be 6/16 but since the 6 is an even number, split the whole thing in half - 3/8. If thats too big, then you need to double the original fraction - 5/16=10/32 and the next 32nd bigger would be 11/32. Its all in doubling or halving the fractions to find your next size.Sounds tough, but it wont require any thought after a few hours of use.
