Introducing our versatile Removable Kinmar® Security Nuts, the ultimate two-way patented security fastening solution for applications requiring both high security and maintenance access. These innovative anti-tamper nuts feature a unique five-segment shaped design manufactured from premium materials including A2 stainless steel, case hardened steel with bright zinc plating, and advanced Geomet coating finishes. Engineered for applications where periodic maintenance or component replacement is necessary, these removable security nuts provide exceptional tamper resistance whilst allowing authorised removal using matching specialised driver sockets, making them indispensable for car park barriers, public transport infrastructure, and maintenance-critical installations across the UK.

What are Removable Kinmar Security Nuts?

Removable Kinmar® security nuts represent the perfect balance between high-level security protection and practical maintenance accessibility. These patented two-way security fasteners incorporate a unique five-segment drive pattern that requires matching driver sockets for both installation and removal, providing robust protection against unauthorised tampering whilst permitting legitimate maintenance operations. The smooth, aesthetically pleasing rounded design eliminates sharp edges and protrusions, making these nuts ideal for public spaces where safety considerations are paramount. Unlike permanent security solutions, these removable nuts enable authorised personnel to perform routine maintenance, component upgrades, or emergency repairs without compromising the long-term security integrity of the installation, delivering cost-effective security for applications requiring regular access.

Please note that to preserve the integrity of our security products, the relevant tooling is not available online.

It is available by request, and only to registered businesses.

Key Applications and Industries:

• Car Park Security Systems: Essential for barrier arms, entry gates, ticket dispensers, and payment terminals where daily operation requires regular maintenance access whilst preventing revenue loss through tampering.
• Public Transport Infrastructure: Securing bus stops, railway platform furniture, ticket machines, and information displays where regular cleaning, maintenance, and seasonal updates necessitate authorised access.
• Playground and Recreation Equipment: Protecting children's play equipment, sports facilities, and outdoor fitness apparatus where safety inspections and component replacement require periodic removal without permanent damage.
• Street Furniture Maintenance: Ideal for benches, bins, signage, and lighting fixtures in urban environments where councils need regular access for cleaning, repair, and seasonal decorative installations.
