4 Hole Security Fasteners
4-Hole security screws and nuts are reusable and fastened with a special 4 pronged driver tool. Each prong locates within one of the 4 holes making up the drive. Suitable for use in low to medium torque applications, these are 2-way, reusable fixings ideal for use where aesthetic appearance is the most important consideration and where maintenance is required.
These fixings are tamper proof, so can help deter vandalism or attempts to undo the fixings, although they are usually selected primarily for their low profile and aesthetic appearance, e.g. on stainless steel architecture, balustrading and glass panels. They can also be used on access covers to deter unauthorised access.
All 4-hole products are made to order.
