Armour Ring™
A simple conical collar which renders a standard hexagon nut or bolt tamper resistant.
The Armour Ring™ can be applied to any British or DIN standard hexagon nuts or bolts using a standard hammer or Armour Ring™ installation tool. It leaves a smooth clean finish which is often favoured by Health & Safety executives and isn’t governed by a torque level like some one-way fasteners.

Has been Home Office approved.
Available in Steel Zinc Plated (CR-3) and 303 S31 Stainless Steel.
