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
• 1/4" 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.
