Hi everyone,

Can anyone please tell me the correct countersink angle for # 6 "SPAX"
flat head screws ? Most US screws are countersunk for 82 degrees, but I
thought someone had told me SPAX screws were 90 degrees. I am screwing
a flat steel plate to wood, and I need the coutnersink to match up
correctly with the screw flat head. I think the spax screws are
sometimes called "high performance serrated thread" screws.

Thanks for your help.
John

I just found from www.spax.com that the spax screws do use a 90 degree
countersink.
