Aluminum Black Nylock Half Nuts, 1/2 Inch -20 Thread, Pack of 25

Built for secure fastening in tight spaces, these steel black thin Nylock nuts are ideal for automotive, racing, and fabrication projects where low profile hardware is a must. The nylon insert helps resist loosening from vibration, while the thin design saves critical thread engagement room on short studs or bolts. Finished in a sleek black anodized style, they pair perfectly with exposed hardware builds and professional race setups alike.
