2-Hole Pig Nose Security Nut

These 2-Hole Pig Nose Security Nuts offer an aesthetically pleasing security solution with low-to-medium security resistance for lower torque applications.

They host a re-usable two-way drive, which is ideal for applications in which maintenance is required. They require a special insert bit to insert and remove that fits the two drilled holes in the head.

2-Hole Security Nuts are more prone to cam-out than other security nuts such as the Kinmar or Wave. Users should also be aware that when tightening the nut the tools are prone to bending or breaking after prolonged use. Purchasing additional tools as back-up is advised.

The two holes can be drilled at different distances between centres, so it is advisable to purchase the screws and corresponding bits from the same supplier.

Available in A1 Stainless Steel as standard from Fastenright.

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