Steel Torx Plus Rounded Head Thread-Forming Screws for Soft Metal

The deep, six-lobe recess keeps drivers from slipping when installing these screws in soft metals such as brass, aluminum, and copper. Torx Plus drives withstand even more torque than Torx. Also known as Taptite® screws, these have a tri-lobular shank that presses threads into material for a tight fit. The unthreaded lead-in point starts threads cleanly and keeps the screw aligned in the hole. Their rounded head creates a finished look.

Length is measured from under the head.

Stainless Steel Torx Plus Flat Head Screws

The most corrosion-resistant Torx Plus flat head screws we offer. Made of stainless steel, they won't rust or corrode when exposed to moisture and chemicals, but they're not as strong as alloy steel. With larger lobes than Torx drives, Torx Plus withstands even more torque without slipping and stripping the drive.

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.

Stainless Steel Torx Plus Rounded Head Thread-Forming Screws for Plastic

Tri-Lobe Shank Cross

Section

Neither moisture nor a heavy hand can damage these screws. The deep, six-lobe recess withstands even more torque than a Torx drive to prevent slipping as you install screws in plastic. They press threads into molded or cast holes and won’t crack or distort the material. Use them to fasten plastic components, enclosures, and panels. The rounded head creates a finished look.

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.

Tri-Lobe—The tri-lobular shank forms threads in thermoplastics such as polypropylene and ABS. These screws displace material to create a tight fit that resists vibration and prevents backing out. Because the shank isn't round, the diameter will vary slightly depending on where you measure it. They're comparable to Plastite 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.

Screwdrivers

A staple in any toolbox, these are your go-to screwdrivers for routine maintenance and repair. The handle is made from a combination of soft, grippy plastic for high torque and smooth, hard plastic for quick grip adjustments and high-speed turning. It's also contoured to maximize comfort and minimize hand strain, fatigue, and blisters, even with extended use.

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.

Torx Plus Bits

Hex Shank

Quick-Change Hex

Shank

With larger lobes than Torx bits, these deliver even more torque without slipping and stripping the drive. They have a similar profile to Torx but are not recommended for use with standard Torx screws.

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.

Torque-Limiting Keys

T-Handle

Often used to install carbide inserts in cutting tools, these keys have a small handle that prevents you from generating too much torque when turning a fastener.

T-Handle—These keys have a wider handle than L-keys, so they're easier to grip.

Black-Oxide Steel—The coating offers minimal corrosion resistance, so these keys are best for dry environments.
