Key Features

A simple conical collar which is hammered over any standard hexagon bolt head or nut, rendering it tamper resistant. This security fastener has the advantage of not being governed by torque and can be applied to existing fasteners. 

Another advantage of using the Armour Ring™ is that it leaves a smooth cover to existing fixings. Armour Rings™ are suitable for any British standard or DIN standard hexagon bolts and nuts, including hex head coach screws.

Please note: Most security screws are not manufactured to DIN or ISO standards and head dimensions can vary considerably from manufacturer to manufacturer. If head dimensions are critical, please specify at time of order.
