The Pin Hex security sex bolt is a tamperproof adaptation of the sex bolt, also known as a barrel nut, barrel bolt, Chicago screw, architectural bolt or post and screw.

This type of security fastener has a barrel-shaped flange and protruding boss that is internally threaded. The boss sits within the components being fastened, and the flange provides the bearing surface.

The security sex bolt (male – female bolt) and accompanying tamperproof security machine screw sit flush on either side of the surfaces being fastened. It is normally chosen because of its low profile compared to other nuts.
