armour-ringThe Armour Ring enclosure works to convert conventional nuts or hex head bolts into tamperproof fastenings by enclosing them in a tamper-proof collar.

The Armour-ring itself is 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 easily retro fitted to existing nuts and bolts or applied to newly installed ones. 



Armour Ring Applications

The Armour Ring can be used when nuts or bolts are installed, or can be retrospectively fitted to existing installations such as at this skateboard park.

Obviously once the Armour Ring has been fitted, it prevents anyone from tampering with the fastener, ensuring in this case that bolts are not loosened by vandals or others, which could lead to the collapse of the structure, possibly causing injury to skatepark users.



Armour Ring Availability

Armourings are available for immediate delivery from stock - with a choice of materials; BZP steel or Stainless Steel (A2).

Stock sizes range from M6 to M20
