Steel Socket Head Screws


Fully Threaded	Partially 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 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.

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.

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.

Stainless Steel Hex-Drive Flat Head Screws

The most corrosion-resistant hex-drive 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 six contact points, the hex drive withstands more torque than slotted and Phillips to securely grip your driver 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.

Steel Hex-Drive Flat Head Screws

Our strongest hex-drive flat head screws. They're made of alloy steel, so they have nearly twice the tensile strength of other screws. With six contact points, the hex drive withstands more torque than slotted and Phillips to securely grip your driver without slipping and stripping the drive.

Length is measured from the top of the head.

Standard Profile—Standard-profile heads are the most common choice for flat head screws.

Undercut Profile—About a third thinner than standard heads, the undercut profile fits into shallow holes in thin material. The thin head also has more threading on the shaft, so they're often used to keep short screws from coming loose.

Stainless Steel Hex-Drive Shoulder Screws

These screws hold up against moisture and chemicals better than their steel counterparts, but they aren't as strong.

Check out our Made-to-Order Stainless Steel Hex-Drive Shoulder Screws if you don't see the shoulder length you need.

18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they won'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.

Highly Corrosion-Resistant Black-Oxide 316 Stainless Steel—Combines a finished appearance with the rust resistance of 316 stainless steel. Even if the coating wears off, these screws will hold up against corrosive agents in most environments, including salt water and most chemicals.

Steel Cup-Tip Set Screws

Made of alloy steel, these screws are strong enough to hold components without wearing down. The tip has thin edges that dig into surfaces for a secure hold. They often lock gears, pulleys, and other transmission components onto shafts.

Black-Oxide Alloy Steel—These screws have a dark matte finish that offers minimal corrosion resistance, so they're best for dry environments.
