Stripped bosses usually come down to the wrong screw thread for the plastic. A thread forming screw designed for plastics gives a tighter grip.

ASL supplies screws for thermoplastics and trilobular thread forming screws for plastics and metal.

Tell us about the failure and we will help find a better screw.
