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.

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.

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.

Bit Sets

Hex Shank

Have a range of bits ready to turn the most common screw styles and sizes.

Hex Shank—Also known as insert bits, these snap into hand tools. If you want to use them with power tools, attach a bit adapter (not included).

Steel—Best for dry environments, since moisture will cause these bits to rust.

Tamper-Resistant Tri-Groove-Drive Steel Round Head Screws

Good luck trying to force off these screws. The tri-groove drive has a sloped shape with three notches that makes it nearly impossible to grip without a tri-groove driver. They're often found on electrical boxes, machine control panels, and critical equipment where unauthorized access is a concern.

Length is measured from under the head.

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

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.

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 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.

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.

Torq-Set® Bit Sets


Hex Shank	Quick-Change Hex Shank

Similar to Phillips bits, but with offset wings for a better grip. The bits in these sets are less likely to slip out of the screw head and damage the fastener.

Hex Shank—Also known as insert bits, these snap into hand tools. If you want to use them with power tools, attach a bit adapter (not included).

Quick-Change Hex Shank—Lock these bits directly into power tools. They won't wobble as much as bits paired with an adapter, so they are the best choice for high-precision tasks.

Steel—Best for dry environments, since moisture will cause these bits to rust.

Plain-Grip Screwdrivers

Ideal for industrial maintenance, these no-frills screwdrivers withstand years of heavy use in the shop and on the jobsite. The hard plastic handle won't crack or wear out from drops and scrapes. It's also easy to wipe down and won't get sticky or gummy when exposed to oils or chemicals, unlike a soft handle.

Premium—The best screwdrivers available, with tips machined to tight tolerances for the tightest possible fit in fastener recesses. The snug fit means they'll turn screws quickly without slippage, which would wear on screw heads and the driver's tip.

Standard Length—The most common screwdriver length for a specific drive size.
