Stainless Steel Truss Head Phillips Screws

Our most corrosion-resistant truss head Phillips screws. Their wide head spreads out pressure without adding a washer and reduces the risk of crushing thin material, such as sheet metal. The Phillips drive easily aligns with drivers and withstands more torque than slotted drives, but drivers slip when you apply too much force.

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.

Black-Oxide 18-8 Stainless Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They won't rust in wet and outdoor environments, but they don't hold up to the harsh chemicals that 316 stainless steel can.

Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these screws won't degrade when exposed to harsh weather, salt water, and most chemicals.

Stainless Steel Oversized Truss Head Slotted Screws

Up to twice the size of standard truss screws, these spread pressure even further to prevent crushing thin material, such as sheet metal. With only two contact points, the slotted drive can't withstand much torque, so it's best to hand-tighten them. Also known as shutter screws.

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.

Steel Truss Head Slotted Screws

Wider than other rounded heads, the truss head spreads pressure over a large area without adding a washer. This reduces the risk of crushing thin material, such as sheet metal. With only two contact points, the slotted drive can't withstand much torque, so it's best to hand-tighten them.

Length is measured from under the head.

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.
