6 Lobe Pin TX Countersunk Security Barrel Nuts & Sex Bolts Stock Sizes
- All parts can be matched for a finish appearance.
- Ideal for use in architectural stair casing and balustrade.
Previously only available as button head fasteners, the 6 Lobe Pin TX Countersunk version offers an off-the-shelf solution for applications requiring a flush finish. These security barrel nuts offer a medium level of security and are suitable for high torque use.
They are also known as sex bolts or Chicago screws and feature an internally-threaded barrel in which a matching screw can be fastened into. It is important to consider both the hole diameter and the thickness that you are closing when deciding which size will be suitable.
These security barrel nuts are often used with a matching Pin TX Countersunk Security Machine Screw for applications where both sides are exposed to potential tampering or theft but can be used with any machine screw of the correct size.
Available as standard in A2 stainless steel, but can be manufactured to your requirements.
