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—Best for dry environments since moisture will cause these screws to rust. They have a dark, matte appearance.

Blue-Dyed Zinc-Plated Alloy Steel—The distinctive blue color makes it easy to tell these metric-sized screws apart from inch screws.

Stainless Steel Socket Head Screws

Fully Threaded

Partially 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.

Low-Profile Steel Socket Head Screws with Pilot Recess

Hex with Pilot

Recess

For extra gripping power, these low-profile screws have a pilot recess in the hex drive. Fasten them with an extended-tip L-key (sold separately). You can also tighten them with a standard L-key, but it won't grip the hex drive as securely. With a screw head that's about half the size of standard-profile ones, these screws are less likely to snag components. However, they aren't as strong as alloy steel ones with larger heads.

Length is measured from under the head.

Black-Oxide Alloy Steel—Best for dry environments since moisture will cause these screws to rust. They have a dark, matte appearance.

Zinc-Plated Alloy Steel—A common choice for areas with occasional exposure to moisture.

Wall-Mount Angled-Drive Ball-Tip L-Key Sets

Store L-keys that work in corners and tight spaces within reach. These rugged metal cases mount to your workstation and keep your tools protected when closed. When open, they offer full access to your set without taking up extra space. These L-keys have a ball tip on the long leg that engages the drive with less contact than a straight tip. Ball tips are handy for corners and tightly-packed areas, such as control panels and junction boxes. However, they don’t grip as tightly as straight tips and may strip the fastener if you crank them too hard.

Alloy Steel—These L-keys handle high torque without bending or breaking, so they’ll last a lifetime.

Long—The most common option, these L-keys have a balanced length for everyday reach and torque.

Angled-Drive Ball-Tip L-Keys

Turn screws at an angle when you can’t access them head on. These L-keys have a ball tip on the long leg that engages the drive with less contact than a straight tip. Ball tips are handy for corners and tightly packed areas, such as control panels and junction boxes. However, they don’t grip as tightly as straight tips and may strip the drive of the fastener if you crank them too hard. These L-keys are precision manufactured to tight tolerances.

Alloy Steel—These L-keys handle high torque without bending or breaking, so they’ll last a lifetime.

Long—The most common option, these L-keys have a balanced length for everyday reach and torque.
