Kinmar® Removable 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.
