Discover more about the Armour Rings™ range.

Armour Rings are a simple and unique conical collar which convert standard Hex Bolts and Hex Nuts into tamper resistant fasteners. As the Armour Ring™ can simply be installed onto any British or DIN standard hexagon nut or bolt using a regular hammer, it requires no specialist tooling to operate.

The patented Armour Ring is intended to be an easy to use 1-Way security fastener. They aren’t governed by torque and are designed to be used for maintenance free applications, giving them some advantage over other similar permanent fixings.

Favoured by Health & Safety executives, along with approval from the Home Office, Armour Rings provide a smooth, clean finish which is free from sharp edges and similar in appearance to a Conical Washer. Common applications for this type of tamper resistant fastener cover are security grilles and for securing public installations such as park benches.
