Nylon Acorn Cap Nuts are non-magnetic and corrosion resistant. Used in applications where a finished look is needed. They also protect the ends of screws and bolts. Fasteners are precision molded or machined of Nylon 6/6 - a highly crystalline, light-weight, high melting thermoplastic resin. The mechanical advantages include toughness; good thermal properties; abraision, friction, and chemical resistance. Parts are natural but can be dyed black or various colors on request! Specify color at Checkout. Max. tensile strength: 12,000 PSI., resistance to heat: 270-300 deg F.
 

Acorn Cap nuts are end protective on bolts or screws and have a finished appeal in many outdoor and industrial applications. 18-8SS, which is a Type 300 series Stainless Steel, is one of the most widely used corrosion resistant metals for threaded and non-threaded fasteners. Uses include many marine, electrical and food industry applications. It has fair machinability and cold forming properties. Max. tensile strength: 150,000 PSI.
