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.

Low-Profile Stainless Steel Socket Head Screws with Pilot Recess

Hex with Pilot

Recess

For extra gripping power, these low-profile, corrosion-resistant 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.

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.

L-Keys

The highest quality L-keys you can buy for tightening and loosening screws. Our L-keys are precision manufactured to tight tolerances for an exact fit.

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

Short—A short long leg fits into tight spaces where you have less room to swing, making these ideal for confined areas.
