Nylon Insert Nuts 7/16-20 10pk

ALLSTAR PERFORMANCE Nylon Insert Nuts 7/16-20 10-pack are essential fasteners designed for automotive applications, particularly in high-vibration environments. These lock nuts are ideal for securing components such as intake manifolds and performance drivetrains, ensuring that fasteners remain tight under extreme operating conditions.

The nylon-insert design features a deformable nylon collar that grips the bolt threads when torqued, creating a mechanical lock that resists loosening due to vibration. This design helps prevent damage to the threads, unlike all-metal lock nuts, which can gall or strip over time. While these nuts can be reused, it is important to monitor the condition of the nylon collar, as it may wear out after several uses.

These nylon insert nuts are particularly beneficial for engine builders and race teams who frequently assemble and disassemble components. They are suitable for various applications, including small engine work, fuel system upgrades, and header installations, making them a versatile choice for both professionals and enthusiasts.
