Stainless Steel Button Head Torx Plus Screws

Image of Product. Front orientation. Rounded Head Screws. Stainless Steel Button Head Torx Plus Screws.

The most corrosion-resistant button head Torx Plus screws we offer. Made of stainless steel, they won't rust, but they're not as strong as alloy steel. The button head looks similar to a pan head, but it's lower and more compact, taking up less space. With larger lobes than Torx drives, Torx Plus withstands even more torque without the driver slipping and stripping the drive.

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 Torx Plus Rounded Head Thread-Forming Screws for Thin-Walled Holes in Plastic

Thread these screws into thin-walled holes without damaging the drive or your workpiece. The deep, six-lobe recess withstands more torque than a Torx drive to prevent slipping. These screws have narrow-angle threads that prevent cracking and discoloration in molded plastics, such as ABS, PVC, and polycarbonate. The rounded head creates a finished look.

Length is measured from under the head.

Stainless Steel Pan Head Torx Plus Screws

Image of Product. Front orientation. Rounded Head Screws. Stainless Steel Pan Head Torx Plus Screws.

The most corrosion-resistant pan head Torx Plus screws we offer. Pan heads have a moderate height and width profile, offering a middle ground between narrower button heads and wider truss heads. With larger lobes than Torx drives, Torx Plus withstands even more torque without the driver slipping and stripping the drive.

Plain Grip

Make fine-tuned adjustments on a variety of small, delicate components, such as electronics, miniature models, and microscopes. These screwdriver sets give you better control than a standard screwdriver to avoid stripping tiny screws or cracking fragile materials. Press the end of the handle with your palm to apply constant pressure while turning the body of the screwdriver with your fingertips. They are also known as precision and miniature screwdrivers.

Black-Oxide Steel—These screwdrivers withstand occasional moisture.

Chrome-Plated Steel—The bright, shiny plating resists salt water and chemicals better than other finishes and is less likely to wear off.

Plain Grip—Made of hard plastic for durability.

Torx Bits

Hex Shank

For Power Tools

Get a grip with less slip. These bits have a six-lobe shape that grips fasteners so they won't slip and damage the drive. Also known as star bits.

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.
