Engineering Plastic Screws, Nuts & Components

Description

A broad selection of engineering plastic fasteners and components, covering multiple head styles and a wide range of metric and inch thread sizes. Suitable for equipment designs requiring lightweight, corrosion-resistant, and electrically insulating fastening solutions. Materials may be selected to suit temperature and chemical exposure requirements (e.g., PEEK, PPS, PVDF, PP, RENY, PVC, Nylon, PTFE, PEI, TPI, PPGF, PEEK+GF).
