Built to Your Specific Requirements

Finish: Unfinished
Fasteners: We have the ability to tap Acetal and to install fasteners. We do not carry any stocked fasteners for plastics, but it is possible to order them on request, for additional lead time and cost. If you do choose to tap this material, it is recommended to use a coarse pitched thread over a fine pitched thread. A more cost-effective option for installing fasteners would be to install self-clinching nuts or studs into the mating metal parts, which could be screwed into. If you do decide to go with a threaded insert, PennEngineering & Manufacturing Corp has a large variety of sizes available.
