Steel Threaded Nut Inserts with Nylon Locking Nuts - 1/4"-20 Fasteners for Race Car Panels

Panel fastening on a race car demands reliability—vibration, thermal cycling, and repeated assembly cycles will loosen standard fasteners. These steel threaded nut inserts with nylon locking nuts provide the secure, repeatable clamping force you need for dash panels, body panels, and access covers without stripping threads or requiring threadlocker compounds. Install once, trust it holds.

Built for high-vibration environments, the nylon insert creates a positive mechanical lock that resists loosening under track conditions while remaining reusable through multiple builds and tear-downs. Whether you're fabricating a race car interior or upgrading bolt-on body panels, these inserts simplify assembly and eliminate the guesswork of panel retention.
