6 Lobe Pin TX Button Head Security Barrel Nuts & Sex Bolts

6 Lobe Pin TX Button Head Security Barrel Nuts and Sex Bolts are two-way security nuts offering resistance to possible tampering. This fastener requires a special driver bit to fix or remove.

This security sex bolt is a tamper-proof adaptation of the commonly known sex bolt, which can also be referred to as a security barrel nut/bolt.

  • Tamper Proof TX with Medium Security Resistance.
  • Usable for high torque applications.
  • Ideal for use in architectural stair casing and balustrade, protecting playground equipment, furniture and signage.
  • Parts can be matched for a finished appearance.

These 6 Lobe Pin TX Security Barrel Nuts and Sex Bolts host a domed Button Head with larger diameter, offering a clean and professional finish to any application. Ideal for use with 6 Lobe Pin TX Button Head Security Machine Screws, also available at Fastenright.

This type of 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 (consisting of a male and female bolt), and accompanying tamperproof security machine screw sit flush on their side of the surfaces being fastened.

It is normally chosen for applications due to its low profile compared to other nuts. Its 6 Lobe Pin TX drive feature is also available as a 2-Hole or Clutch drive to aid in tightening the fastener.

Available at Fastenright in Stainless Steel as standard, with thread diameters from M4 to M12. 6 Lobe Pin TX Countersunk Security Barrel Nuts & Sex Bolts are also available.

Non-standard sizes and materials are available to order as specials, including custom parts made to drawings.
