About Hex Head Screws and Bolts

Hex Head Screws

Use these general purpose screws for a variety of fastening applications.

Heavy Hex Head Screws

These screws meet specifications for high-pressure or structural applications.

Flanged Hex Head Screws

Eliminate the need for a separate washer—these screws distribute pressure where the screw meets the surface without taking up as much space as a washer.

Vibration-Resistant Hex Head Screws

Prevent loosening from vibration with these screws, which have a locking feature to hold them tight.

Sealing Hex Head Screws

An O-ring under the head prevents leaks and seals out contaminants.

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.

Tension-Indicating Hex Head Screws

An indicator dot changes from red to black when the screw is properly tightened. If it comes loose, the dot changes back to red.
