Tamper-Resistant Drilled Spanner Stainless Steel Rounded Head Screws for Sheet Metal

Image of Product. Front orientation. Contains MultipleImages. Tapping Screws. Tamper-Resistant Drilled Spanner Stainless Steel Rounded Head Screws for Sheet Metal.

A two-hole drive deters tampering and a rounded head creates a finished look. Also known as pig-nose screws, these turn only with a drilled spanner driver. The two contact points won’t withstand much torque, so they’re best for light duty fastening. The pointed tip starts a hole in sheet metal up to 0.025" thick, but for thicker material you’ll need to drill first. These screws resist corrosion.

Length is measured from under 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.

Screwdriver Bits—Turn screws by hand for more control and less chance of overtightening compared to power tools.

Power Tools Bits—Pair with your power tools to turn screws more quickly than manual tools.

Tamper-Resistant Drilled-Spanner Stainless Steel Flat Head Screws for Sheet Metal

Image of Product. Front orientation. Contains MultipleImages. Tapping Screws. Tamper-Resistant Drilled-Spanner Stainless Steel Flat Head Screws for Sheet Metal.

A two-hole drive deters tampering with screws that install in countersunk holes. Also known as pig-nose screws, these require a drilled spanner driver to turn them. However, the two contact points won’t withstand much torque, so they’re best for light duty fastening. They have a flat, beveled head to sit flush with surfaces. The pointed tip starts a hole in sheet metal up to 0.025" thick, but for thicker material you’ll need to drill first. Made of stainless steel, these screws resist corrosion.

Length is measured from the top 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.

Screwdriver Bits—Turn screws by hand for more control and less chance of overtightening compared to power tools.

Power Tools Bits—Pair with your power tools to turn screws more quickly than manual tools.
