PEEK Nuts – Advanced Polymer Nuts for Corrosive & High-Temperature Environments
Product Description
PEEK Nuts are high-performance thermoplastic fasteners engineered for use in extreme environments that demand resistance to heat, chemicals, and radiation. Manufactured from Polyether Ether Ketone (PEEK), these nuts provide a unique combination of mechanical strength, low friction, and chemical resistance—making them an ideal alternative to metal nuts in mission-critical applications.
At SM Fasteners, we supply precision-machined PEEK nuts in standard hex, heavy hex, and specialized nylock variants with tight tolerances and custom threading options.
