Nylon Insert Nuts 3/8-16 10pk

The Nylon Insert Nuts 3/8-16 10pk by ALLSTAR PERFORMANCE are essential fasteners for engine builders, fabricators, and DIY mechanics engaged in high-performance projects. These lock nuts are specifically designed to prevent loosening due to vibration, a common issue in engine and drivetrain assemblies that face continuous shock loads and thermal cycling.

Each nut in this 10-pack features a 3/8-16 thread specification, which is a unified thread standard (UNC). The nylon insert grips the bolt shank as the nut is threaded on, creating mechanical friction that helps lock the fastener in place. This design eliminates the need for lock washers or thread-locking compounds, simplifying assembly.

Professional engine shops, race teams, and restoration specialists benefit from the reliability of nylon insert lock nuts across various applications, including carburetors, intake runners, and accessory mounting points. The compact 10-pack, weighing 0.19 lbs, is easy to store in any tool kit or pit bag, making it a practical choice for any mechanic.
