These screws are used to screw light guage steel, galvanized or aluminum roofing panels (24ga - 18ga) to a structural purlin. They are made from case hardened steel. They are a #12 screw, 1 1/4" long, (appx 1" of thread) have a self sealing washer, have a self drilling point and use a 3/8" standard screw bit.
The set is barely used and in better condition than may be thought. The case has been getting dirty sitting in the top section of my tool box, but the ratchet is sparkling clean and all the bits except for 1 look untouched. The smaller of the 2 regular screwdriver bit (marked CM-17) has the corner chipped away.
