Screws and Bolts

Tight-Spot Hex Head Screws

A high-strength alternative to blind rivets, use these screws when only one side of the material is accessible.

Vented Hex Head Screws

Drilled through the head and shaft, these screws vent fluid and gases trapped below the screw, making them good for vacuum applications.

Wire-Lockable Retainers for Hex Head Screws and Nuts

Place one of these retainers around a hex head screw or nut, then attach wire to lock the screw or nut in place and keep it from loosening.

Vented Socket Head Screws

Drilled through the head and shaft, these screws vent fluid and gases trapped below the screw, making them good for vacuum applications.

High-Vacuum Cleaned-and-Bagged
Vented Socket Head Screws

Fasten these screws inside a high-vacuum system without bringing in contaminants.

Alloy Steel Hollow-Lock Set Screws

Also known as jam set screws, these lock other screws in place, hold pins, and adjust spring tension. A black-oxide finish provides corrosion resistance in dry environments.

Stainless Steel Hollow-Lock Set Screws

Stainless steel set screws have excellent corrosion resistance in most environments.

Vented Cup-Point Set Screws

These inch size set screws are vented to allow fluid and gas to pass through.

Metric Vented Cup-Point Set Screws

These metric set screws are vented to allow fluid and gas to pass through.

Vented Flat Head Screws

These screws are drilled through the shaft to vent fluids and gases trapped under the screw.

Metric Vented Flat Head Screws

To vent fluids and gases trapped under the screw, these metric screws are drilled through the shaft.
