Steel Flanged Hex Head Drilling Screws

Save time and effort with screws that drill and fasten in one step. The hex head gives you a firm, high-torque grip with a nutdriver or socket. Screws have a flange under the head that spreads the load to prevent crushing thin metal.

Length is measured from under the flange. Head height includes the flange.

Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

Stainless Steel Phillips Oval Head Screws for Sheet Metal

These corrosion-resistant screws have a decorative rounded top that peeks out from the surface of trim work. Beveled under the head, they’re often used in countersunk holes. Their pointed tip starts a hole in sheet metal up to 0.025" thick, but for thicker material you’ll need to drill first. The Phillips drive handles enough torque to keep drivers from slipping.

Length is measured from the edge of the head.

18-8 Stainless Steel—The choice for wet and outdoor environments, these screws resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.

Steel Phillips Flat Head Drilling Screws

In one step, drill and fasten trim, brackets, and other objects with countersunk holes. These screws have a flat, beveled head to sit flush with surfaces. The Phillips drive withstands less torque than a hex drive, so drill with even, steady pressure.

Length is measured from the top of the head.

Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
