...I once bought a box of 10-32 x 1" self-tapping/drilling, hex head,stainless steel screws..tho' Ive been told they don't make such an animal.I've searched everywhere,and the only thing I can come up with is a "thread-cutting" screw..with that,ya gotta drill a pilot hole first,then thread in your screw in..With the other,ya just drill it in with your 5/16 hex-bit,and you're done..I know I'm not cracking up..(yet)...has anyone seen,or used this kind of screw..?
I use them for bonding ground lugs on FS boxes,and swimming pool ladders,structural members etc..I then attach a 10-32 nut,and cinch it up real tight,to make a good bond...
