Nylon Thumb nuts are non-conductive and corrosion resistant. Hand tightening allows adjustments with turn of the wrist...no wrench needed! 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.
 

Thumb Nuts allow hand tightening and are used in many applications where a wrench is not needed! 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.
 

Thumb Nuts allow hand tightening and are used in many applications where a wrench is not needed! The most common alloy of copper, brass is two-thirds copper, one-third zinc. It is non-magnetic with good strength and toughness, high electrical conductivity, and an attractive lustrous finish. It has good corrosion resistance but not in salt water. Brass is commonly used by the electrical and communications industries, builder’s hardware, and some marine applications. Tensile strength: 55,000-65,000 PSI.
