Product Summary:
Knurled screws are designed to create ridges that provide enhanced grip. The screws are fully threaded and are metric. Nylon has a very low coefficient of friction, making it popular for applications where wear resistance is required, such as fasteners and cable ties. It is one of the most widely used plastics in the world, with all grades retaining high strength and offering exceptional wear resistance. It has corrosion, chemical and electrical resistance. Tough lightweight, nylon fasteners offer excellent electrical insulation properties and are non-corrosive and non-magnetic. An alternative 50% glass filled nylon version is also available.
