Hillman Group 180147 Nylon Insert Lock Nut, 1/4-Inch by 20-Inch, 100-Pack

Product Description Hillman 1/4"-20 zinc-plated nylon insert stop nuts are designed to create secure, vibration-resistant fastening connections when used with compatible bolts and threaded rods. These lock nuts feature an integrated nylon insert that grips the bolt threads as the nut is tightened, helping prevent the nut from loosening during use. Commonly referred to as nylon insert lock nuts or Nylock nuts, these fasteners are widely used in construction, automotive assembly, equipment maintenance, and mechanical installations where reliable fastening performance is required. The nylon insert creates additional friction against the bolt threads, helping maintain a tight connection even in applications exposed to vibration, movement, or repeated mechanical stress. This locking feature helps improve the long-term reliability of the fastening system. These nuts are designed for use with 1/4"-20 USS coarse thread bolts or threaded rods, ensuring proper thread engagement and dependable fastening performance. They can also be used alongside washers of the same size and finish to create a complete fastening system. Each nut is constructed from durable steel and finished with a zinc-plated coating that provides moderate resistance to rust and corrosion. This protective finish helps extend the lifespan of the hardware in general-purpose indoor and light exterior applications. Packaged in a convenient C-Pak containing 100 lock nuts, these fasteners are ideal for contractors, mechanics, builders, and DIY homeowners working on equipment assembly, structural installations, mechanical repairs, and general hardware fastening projects. From the Manufacturer The Nylon Insert Lock Nut features an integrated nylon insert that grips bolts to help resist vibration effects.
