Kinmar® Permanent A2

Unique high torque security drive. This patented system is a superior alternative to the shear nut, having the advantage of not leaving any unplated surfaces and not being governed by the shear point, enabling an accurate and reliable torque rating to be achieved. This security fastener can be re-torqued if required.

• Manufactured in A2 Stainless Steel, suitable for outdoor use.
• Requires matching driver socket.
• This is a permanent security fixing.
• Removable Kinmar nuts are also available.

Kinmar Permanent security nuts are also available in bright zinc plated steel and galvanised steel.
