Jam Nuts 5/8-18 RH Thin OD Alum 10pk

The Jam Nuts 5/8-18 RH Thin OD Alum 10pk from Ti22 PERFORMANCE is designed for precision fastening in high-performance engines, fuel systems, and custom automotive builds where thread security and minimal profile are essential. These aluminum jam nuts are ideal for engine builders, fabricators, and motorsports enthusiasts who require reliable fastening in compact spaces.

Manufactured from aircraft-grade aluminum, each nut in this 10-pack features a thin outer diameter (OD) profile that minimizes clearance requirements while maintaining a thickness of 1/4 inch for adequate clamping force. The 5/8-18 right-hand thread specification ensures compatibility with standard fastening applications, and the natural aluminum finish provides corrosion resistance suitable for fuel and coolant environments.

These jam nuts excel in dual-nut locking applications where one nut secures against another to prevent vibration-induced loosening on fuel rails, AN fittings, and carburetor linkage. The 10-pack quantity provides sufficient spares for complete engine assembly, transmission work, or multiple vehicle projects. Installation requires a standard 15/16-inch wrench for ease of use.
