2-Hole Pig Nose Security Nut

2 hole pig nose security nut

  • Pig nose security nuts
  • An aesthetic security solution
  • Low / medium security resistance
  • Reusable 2-way drive
  • Usable for lower torque applications

Reusable fixings, ideal for applications where maintenance is required. 2 holes are drilled into the heads, requiring a special insert bit to insert and remove.

2-hole screws Installation guidance:

The two holes can be drilled at different distances between centres, so we advise purchasing the screws and corresponding bits / drivers from the same supplier.

2-hole security nuts are more prone to cam-out than other security nuts such as the Kinmar and Wave. Users should also be aware that when tightening the nut the tools are prone to bending or breaking after prolonged use, so we recommend purchasing additional tools as backup.

Supplied from stock in A1 stainless steel, other sizes and materials to order.

Special 2-hole security nuts can be made to order including small volume manufacture, modifications and custom parts to drawings.
