Fastening protection for plastic moulds
Engineered fastener manufacturer Spirol Industries has introduced the new CL101 and CL111 range of solid knurled compression limiters. They are designed to preserve the integrity of a plastic threaded joint when a metal bolt is inserted, preventing creep, loosening and eventual failure of the joint.
The CL101 is unheaded and the CL111 is a headed compression limiter. Both are available for M3 to M8 bolt sizes and in lengths of 3mm to 20mm to suit the length of the fastening. They are made from brass and can be either moulded or pressed into position.
The compression limiter absorbs the load when the bolt has been tightened to its recommended value. It isolates the plastic from any excessive compression loads with individual compression limiters having rated load levels from 2.20 to 17.04kN.
