Stainless Steel Socket Head Screws

Fully Threaded

These screws won't rust or corrode when exposed to moisture and chemicals. Their deep, six-point socket keeps hex keys from slipping out and damaging 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 screws can.

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

Steel Socket Head Screws

Fully Threaded

Made of alloy steel, these screws are the standard for high-strength fastening. Use them in high-load applications such as dies, presses, and heavy equipment. The deep, six-point socket keeps the hex key from slipping out and damaging the drive.

Length is measured from under the head.

Black-Oxide Alloy Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.

Stainless Steel Button Head Hex-Drive Screws

These button head screws won't corrode from moisture and chemicals, but they aren't as strong as alloy steel screws. The button head looks similar to a pan head, but it's lower and more compact, taking up less space. With six contact points, the hex drive withstands more torque than slotted and Phillips to securely grip your driver.

Length is measured from under the head.

Stainless Steel Torx Flat Head Screws

The most corrosion-resistant Torx flat head screws we offer. Made of stainless steel, they won't rust or corrode when exposed to moisture and chemicals. With a deep six-lobe opening, these screws prevent slipping and stripping drives. Also known as star drives, they withstand more torque than slotted, Phillips, and hex drives.

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.

Sealing Socket Head Screws

Fully Threaded

Keep out dust and contaminants and lock in air and fluid. As you tighten these corrosion-resistant screws, a rubber O-ring under the head compresses to form a tight seal. The deep, six-point socket keeps hex keys from slipping out and damaging 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 screws can.

Buna-N O-Ring—These seals won't swell or soften when they touch oil, grease, or fuel.

Silicone Rubber O-Ring—Withstand a wider range of temperatures than Buna-N and Viton® seals without becoming brittle. However, they degrade when exposed to oil, grease, and fuel.
