Correct Countersink angle for SPAX screws
 

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 #6 spax do indeed use a 90
degree countersink, in case it can help anyone.

Hi Matthias,

Thanks for your reply. I did not find any information on the site you
gave, but I emailed them.

Mcmaster Carr told me once that the screws were 90 degrees, and then
another time that they were 82 degrees. If they are made in Germany, I
would guess 90 degrees, but I don't know for sure.

Thanks again,
John
