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
