Tamper Resistant 4-Hole Security Nuts
4-Hole Security Fixings are typically used in design specific applications such as Stainless Steel architecture, balustrading and glass panels.
Tamper-resistant and aesthetically pleasing, the 4-Hole Nut is ideal for lower security resistance where maintenance is required, as the fixing is reusable and a two-way nut, allowing for removal and reinstallation.
The nut features four location holes in the head/face section, which are surrounded by a slim circular groove. Suitable for low-to-medium torque applications, these nuts require a special driver tool to remove and install. This makes the nut tamper proof, reducing the risk of vandals or intruders tampering, or undoing the screws.
Available as standard in Stainless Steel, but specials are also available in a range of other sizes and materials.
Non-standard sizes, materials and finishes are available to order as specials, including small volume manufacture, modifications and custom parts made to drawings.
