FAQ for Contractors:

Q: Are these magnetic?

A: Only slightly. The cold-heading process induces minor magnetism in 304 SS, but they are not fully magnetic like carbon steel.

Q: Can I use these on hardwoods?

A: Yes, but for dense hardwoods (Oak/Walnut), a 1/16" pilot hole is recommended to prevent screw snapping.

Q: Is the length 1/2" inclusive of the head?

A: Yes, Flat Head screws are measured from top to tip. Total length is 1/2".
