Tamper-Resistant Drilled Spanner Stainless Steel Pan Head Screws

The unique two-hole design inhibits tampering. These screws only turn with a drilled spanner driver, making them hard to force with other tools. Also known as pig-nose drives, their two contact points won't withstand much torque, so they're good for light duty tasks. Made of stainless steel, they won't rust or corrode when exposed to moisture and chemicals. Pan heads have a moderate height and width profile, offering a middle ground between narrower button heads and wider truss heads.

Length is measured from under the head.

18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they don'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 Tool Bits—Pair these bits with your power tools to turn screws more quickly than manual tools.

Tamper-Resistant Drilled Spanner Stainless Steel Truss Head Screws

These screws have a wide head that distributes weight and a two-hole design that deters tampering. They only turn with a drilled spanner driver, making them hard to force with other tools. Also known as pig-nose drives, their two contact points won't withstand much torque, so they're good for light duty tasks. Made of stainless steel, they won't rust or corrode when exposed to moisture and chemicals. Their wide head spreads out pressure without adding a washer to reduce the risk of crushing thin material, such as sheet metal.

Length is measured from under the head.

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

Tamper-Resistant Drilled Spanner Stainless Steel Flat Head Screws

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

The unique two-hole design deters tampering. These screws only turn with a drilled spanner driver, making them hard to force with other tools. Also known as pig-nose drives, their two contact points won't withstand much torque, so they're good for light duty tasks. Made of stainless steel, they won't rust or corrode when exposed to moisture and chemicals.

Length is measured from the top of the head.

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

Standard Profile—Standard-profile heads are the most common choice for flat head screws.

Undercut Profile—About a third thinner than standard heads, the undercut profile fits into shallow holes in thin material. The thin head also has more threading on the shaft, so they're often used to keep short screws from coming loose.

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

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

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.

Drilled-Spanner-Drive Tamper-Resistant Nuts

A wide base and large bearing surface make these nuts good for securing large objects. They must be installed and removed with a nutdriver (sold separately). Use them to reduce the risk of unwanted removal for objects in public spaces such as signs, lighting fixtures, and displays.

Zinc—Made from zinc alloy, they're corrosion resistant in wet environments.
