Product Description

Nylon‑insert ("nyloc") lock nut — a hexagon nut fitted with a polymer (nylon) locking collar that provides prevailing torque to resist vibration and back‑off on bolted assemblies. Commonly produced in zinc‑plated steel and stainless steel, these nuts are made to industry dimensions (ASME B18.16.6 / common NE/NTE/NU series) and are available in standard imperial and metric thread sizes (examples: 1/4-20, 1/2-20, M5). They are sold both individually and in small multipacks; the nylon insert engages the mating bolt threads to hold preload without deforming the bolt threads, allowing limited reusability. I could not locate a public GS1/UPC record for the supplied UPC (738287436525) or the exact SKU you provided, so the photos and price offers below are representative product pages and catalog listings for the same nylon‑insert lock nut form, sizes, finishes and pack/unit options cited from manufacturers and distributors.
