Stainless Steel Armour Ring™

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.
