Common bolt thread sizes used on 72 k20 longbed
 

I'm curious as to what the most commonly used bolt sizes used .
I will need to get the appropriate tap/chasers for the truck to clean out the bolt holes after paint. Obviously I will tape any studs
Thanks all.
Apologies if there is a thread already posted. I did a quick search and found nothing

It does depend on what area of the truck you're working on.alot of the sheetmetal is attached with 5/16's coarse thread bolts,some 3/8's.on the engine,depending what engine,there will be 1/4, 5/16's, 3/8's, 7/16's and 1/2 inch coarse thread usually.if you buy or have a tap & die set with SAE standard taps,you'll have all those sizes you need.

If you buy just 2 - 3 sizes, you'll invariably need another size or two after you get started.. Taps and dies, bought individually can get expensive.. Go to Lowes and get this 11 size set..
