hi all, I am making up some t nuts for my Burke #4. (Single slot table). Didn't come with any... Anyway, is there a preferred or standard size stud diameter to use when drilling and taping the T Nuts?

I make the possible range of studs from 3/8" to 7/16". 3/8" Seems a bit lite weight for good work holding and 7/16" seems a tad big for the diminutive size of the t nut.

I really only want to drill and tap these out one time...!

(Edit: since I posted, I found Marks burke thread where he mentions using 3/8 x16 threaded studs for work holding. So will go with that, unless someone advises a better size. )

Thanks

Glenn

Glen, I will measure one of mine for you today when I get home.

3/8 does sound right though.

Glenn,
I use 5/16 , ¼ and ⅜ It depends on what I am working on.
A word of caution don't over tighten with any thing these tables are known for blow outs from over tightening hold downs.
I found a bunch of diesel engine 5/16 bolts and injector hold downs perfect for holding vise or tooling plate also put some paper under your set ups to prevent slipping

Thanks dgehricke, think I will start with 3/8 and maybe do a couple of 1/4" with mini clamps to experiment.
