Manufacturer of the world's most secure fasteners

STANDARD-SECURITY & HIGH-SECURITY OPTIONS

O-Ring Security Screws

Security and Sealed Protection

Securely Sealed

O-Ring security screws in sizes 4/40 (M3) 5/8-11 (M16).

These have a concave groove under the head about ½ the height of the O-Ring, which permits a moisture seal when tightened. There are two ways we manufacture O-ring security screws based on your required quantity. For quantities of 100 minimum, we lathe cut the groove under the head, and then add the O-Ring. For 2,500 pieces or more, we form the groove in the fastener as it’s being headed then add the O-Ring before threading. 

Why Choose a High-Security O-Ring screw?

One industry who benefits from using High-Security O-Rings is the medical device industry. Security is critical for electromechanical medical devices that regulate the body. Securing the outside of the device with one of our patented security drives protects the intellectual property inside, while also sealing the contents from contamination.
