A high-strength alternative to blind rivets, these Class 8.8 steel screws can be used when only one side of the material is accessible. When the screw is tightened, the attached nut expands the sleeve to create a strong clamping force on the back of the material.

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

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

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.

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