2-Hole Pig Nose Security Nut

2-Hole Pig Nose Security Nuts offer an aesthetically pleasing security solution with low-to-medium tamper resistance against vandalism and theft.

Designed for lower torque applications, these parts host a unique two-hole drive which requires a special 2-hole insert bit for installation. The two-way drive provides high reusability for applications where maintenance is required.

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

2-Hole Security Nuts are more prone to cam-out compared to other drives types such as Kinmar Removable Security Nuts or Wave Security Nuts. Users should also be aware that the tools are prone to bending or breaking after prolonged use, therefore purchasing additional tools as a back-up is advised.

2-Hole Pig Nose Security Nuts are manufactured from A1 Stainless Steel as standard, with other materials available to order such as Steel.

Available at Fastenright in thread sizes M5 to M10, with other sizes available on request.

Non-standard sizes, materials and finishes are available to order as specials, including small volume manufacture, modifications and bespoke parts made to drawings. Minimum order quantities apply.

Angled 2-Hole Security Nuts are also available at Fastenright, as well as a huge range of 2-Hole Pig Nose Fasteners.
