A unique fastener
Unalock is a simple system comprising a nut with a conical, slotted, lower section and a compression ring. The compression ring clips to the nut to complete the assembly. The Unalock is threaded to a bolt with the compression ring facing into the bolt. As the Unalock is tightened the compression ring is forced up the cone. This action forces the legs of the conical section inward and presses them into the bolt thread to grip the bolt. This forms a circular vice as the two threads are forced together.
The fastener has a unique patented design GB 2508620. The nut and bolt threads do not just pull against each other on one axis. They are compressed together to become a mated pair!
We even make a blind bolting system which is vibration proof. Ask us about it!
