Standard machine screws and wood screws are a poor fit for ABS. They either strip the boss or split it. The answer is a screw with a thread designed for thermoplastics.

ASL supplies screws for the plastics industry, including thermoplastics such as ABS, plus trilobular thread forming screws.

Send us your boss size and wall thickness and we will advise.
