Kinmar® Security Permanent Bolts

Tamper resistant Kinmar 1-way security bolts

The Kinmar® unique Hi-Torque security bolt, with matching driver, is a permanent fixing and a superior alternative to the shear bolt, leaving no un-plated surfaces.

  • Patented design with unique indentations
  • High torque and resistant to attempted removal
  • Premium security fixing for public areas
  • Fastened quickly using patented tool
  • Nuts can be re-tightened if needed

The unique indentations in the rounded shape of the Kinmar® bolt provide both security and high torque, making this a cost effective and efficient fixing for applications where the highest level of security is essential and maintenance is not required, e.g. security fencing, street furniture, public transport and playgrounds.
A matching driver is required to fasten the bolt and tighten to the desired torque. Should the bolt become loosened due to vibration, it can be retightened using the tool.
The special security Kinmar® permanent tool is designed to fit hand and power tools for fast efficient installation. The tools are restricted in supply making this a premium security fixing that is not available in the public domain.

Kinmar® permanent security bolts are stocked in M8 x 25 and M8 x 40 Bright Zinc Plated or Geomet finish with other sizes and materials available to order.
