INSERTS FOR PLASTICS

INSERTS provide reusable threads and secure tight threaded additional benefit is high load carrying LOAD CARRYINGThe load carrying ability of the joint is enhanced by the larger diameter of the Insert as compared to the screw. INSERTS are generally twice the diameter of the screw and that increases the shear surface fourfold. Pull-out resistance can further be enhanced by increased Insert BYSTRESS RELAXATIONA common problem with bolted joints in plastic applications is that plastic is susceptible to creep or stress relaxation.

There are four main commercial categories of plastics: thermoset, thermoplastics, foam and elastomers. The latter two have limited suitability for Insert installation and should an Insert be required, an application analysis is suggested. Accordingly, these categories are not covered here.
