Title: Nuts!
Post by: chrisgoodwin on 29 July, 2017, 22:53:10
Hi all, I wonder if anyone can give advice on this one.
I am looking for some generic nuts and bolts to keep in my squirrel store to use as the rigid m20 proceeds, there seems to be a myriad of assortments out there and I am confused.
Has anyone recently bought an assortment of nuts and bolts recently?

Nuts usually 1/4 x 26 tpi cycle or bsf, 5/16 x 26 tpi cycle, 3/8 x 26 tpi cycle with larger nuts being 20 tpi cycle. Some owners use BSF its cheaper than cycle in stainless.

For bolts and screws easiest to measure what you need and use high tensile bolts in the appropriate places such as fork pinch bolts.

You can often find bolts to a part number.

Sometimes with an assorted pack you find that the bolts are either just too short or just too long which is frustrating..

Normaly on M20s the thread is british cycle thread 26tpi or in some odd cases 20tpi, however studs going into ally are usually a whitworth thread, I don't think BSF was used on these machines.
