Folks - I don't have much experience with concrete fasteners - the last time I used a screw brand called "Phillips II Kwiktap" and was underwhelmed. I had quite a few not drive in properly and were stripped and unusable when I pulled them out (could be operator error also, but I tried to be careful to drill a deep enough hole and both blow out and vacuum out the dust before driving the screw).
This go round, I will be driving a good number of these to hold up a combination studwall/insulation panel product (it's called Insofast). So I thought I'd see if there was any experience with the various brands of screws. I'll need 3/16" x 3 1/4" long.
Also, the screw type recommended by Insofast is flat head phillips drive, which I hate. McFeely's has a house brand screw with a combination (phillips/square )drive - anyone have experience with it?
All pointers appreciated -
Ken
