Tamper-Resistant Torx Stainless Steel Flat Head Screws for Sheet Metal
 |
Attach components with countersunk holes to sheet metal and discourage tampering. With a security pin in the drive, these corrosion-resistant screws require a tamper-resistant Torx driver to remove. The deep, six-lobe recess handles high torque to avoid slipping and stripping the drive. Screws have a flat, beveled head to sit flush with surfaces. Their pointed tip starts a hole in sheet metal up to 0.025" thick, but for thicker material you’ll need to drill first.
Length is measured from the top of the head.
18-8 Stainless Steel—The choice for wet and outdoor environments. However, these screws won't hold up to the harsh chemicals that 316 stainless steel can.
Power Tools Bits—Pair with your power tools to turn screws more quickly than manual tools.

These screws have a pointed tip that starts a hole in sheet metal up to 0.025" thick, but for thicker material you’ll need to drill first. Screws resist rust and have a rounded head to create a finished look.

 |
Drill and fasten components with countersunk holes and deter tampering. These screws have a deep, six-lobe recess (also known as pin-in-Torx) that turns only with a tamper-resistant Torx driver. Their flat, beveled head sits flush with surfaces.
Length is measured from the top of the head.
Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.
Power Tools Bits—Pair with your power tools to turn screws more quickly than manual tools.

Tamper-Resistant Torx Stainless Steel Rounded Head Drilling Screws
 |
Removable only with a tamper-resistant Torx driver, these screws drill and fasten in one step. The deep, six-lobe recess (also known as pin-in-Torx) prevents drivers from slipping and deters unauthorized access. These screws resist corrosion and have a rounded head to create a finished look.
Length is measured from under the head.
410 Stainless Steel—Tougher and more wear resistant than other stainless steel screws but less corrosion resistant.
18-8 Stainless Steel—The choice for wet and outdoor environments. However, these screws won't hold up to the harsh chemicals that 316 stainless steel can.
Power Tools Bits—Pair with your power tools to turn screws more quickly than manual tools.

 |
Tamper-Resistant Torx Drive |
Deter unauthorized access. With a six-lobe recess and security pin in the drive, these screws require a tamper-resistant bit to install and remove. To create a pilot hole, use a hammer drill or rotary hammer and a compatible bit. Pull-out strength and shear strength are 25% of the ultimate values.
Rounded Head—A low, rounded top gives these screws a finished appearance.
Flat Head—Beveled under the head, these screws sit flush in countersunk holes.
