Security Nuts

Armour Rings feature a simple collar which can be hammered over any standard hex bolt, providing a high level of security as once applied there is no removal tool available. Simply tap into place with a hammer.

Armour rings can be applied to any existing fasteners, providing a retrofittable option to enhance security.

Endeavour shearnuts offer a one way non-removeable security nut solution. The shearnut head is designed to shear leaving a cone nut. The cone nut has sloping sides which are unable to be gripped with pliers, making it a one way security solution.

• Zinc plated shearnut
• 1/2" UNC

• Zinc plated shearnut
• 1/4" UNC thread

Engineered for high-security applications, this CNC machined shearnut is made d from high-grade steel and finished with a corrosion-resistant zinc plating.

Once tightened, the hex portion shears off at a predetermined torque, leaving a smooth, conical surface that cannot be gripped with standard tools.

Pin plugs are designed to be hammered into the drive part of metric hex machine screws, effectively rendering them unremoveable. As such they convert a normal hex screw, into a one way 'security' screw.

• M10 size, to suit M16 hex screws
• SS304 construction
• Hammer pinplugs into the hex drive using a standard hammer. No special tools required.
• Once inserted, pin plugs cannot be removed.
