Description: 6 Lobe Pin TX Security Barrel Nuts & Sex Bolts

6 Lobe Pin TX Security Barrel Nuts & Sex Bolts are two way security nuts offering resistance to possible tampering. The 6-Lobe Pin TX Drive requires a special driver bit to fix and remove.

A security sex bolt is a tamperproof adaptation of the commonly known sex bolt, also known as a barrel nut, barrel bolt, Chicago screw, architectural bolts or post and screw. This type of tamperproof security fastener (security nut) 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. The 6 Lobe Pin TX security sex bolt security drive feature, is also available as a 2-Hole or Clutch drive to aid in tightening the fastener. Non-security sex bolts are also available.
