More About Part Number 278137

These 1/4-20 Nylon Insert Locknuts are made from Steel, which provides the high tensile strength and hardness that many fastening applications require, making it a common choice for structural, metal framing, and general-purpose fastening. Heavy Hex Nylon Insert Locknuts, commonly designated as NU locknuts, are prevailing torque locknuts with a larger hex profile and nylon insert, designed to resist loosening in structural and high-load applications. They feature a Zinc Finish, which provides reliable corrosion protection for general-purpose indoor and light outdoor applications while remaining a cost-effective choice for everyday fastening needs.
