A Bolt that Can't Get Lost

Captivated Security Bolts

Multiple Security Levels

Easy Security - Don't Lose the Fastener

We offer Captivated security screws and bolts in almost every size.

For smaller quantities (100-piece minimum), we can reduce the shank to a diameter below the threads by hand. This method adds on two weeks to delivery.

We have a centerless grinding machine for larger quantities. Minimums as low as 500 pieces with standard delivery times. Call/Email for more information.

The most common application for tamper-proof captivated screws is in a security door that must not lose the security screw when opened. The idea is to put the captivated security screw fully through a pre-threaded hole where it’s unthreaded. The security bolt then remains in the security door when the panel is opened. This eliminates its loss and makes sure the security door remains tamper-proof even after repeated openings.

Captivated bolts can't be lost

The Security Bolt that Secures Itself Too

Security Captivated Screw in a Cover Panel Prevents Unwanted Access

A major cable company in Venezuela uses Key-Rex® Captivated security screws to keep the public (and other cable companies) from tampering with their signals. When the cover is removed, the security fastener stays connected and doesn’t get mistakenly lost.
