S/S 6pt. Fine Nyloc Nuts - 3/8-24 (5)

The S/S 6pt. Fine Nyloc Nuts in 3/8-24 thread size by ARP are precision fasteners designed for critical engine and drivetrain assembly work. These fasteners are essential for automotive enthusiasts and professional mechanics who require reliable components that can withstand extreme engine loads and vibrations.

Constructed from stainless steel, these nuts resist corrosion and maintain their structural integrity in harsh underhood environments. The integral nylon insert (Nyloc design) provides a friction lock that prevents rotation without the need for adhesive compounds. The 6-point design ensures superior grip geometry, reducing the risk of rounding and allowing for consistent torque values.

Ideal for applications such as head work, intake manifold installation, and exhaust work, this five-piece set helps eliminate fastener loosening caused by engine harmonics and road vibration. Mechanics rebuilding small-block and big-block engines will find these nuts particularly beneficial for ensuring secure and reliable assemblies.
