Thin Nylon Insert Nuts 5/16-24 10pk

The ALLSTAR PERFORMANCE Thin Nylon Insert Nuts 5/16-24 10-pack (ALL16071-10) delivers reliable self-locking performance in a compact hex-head design. These steel fasteners feature a nylon insert that prevents vibration-induced loosening without requiring an adhesive, making them ideal for high-vibration applications where fastener security is critical yet removability must be preserved.

Each nut is sized to 5/16-24 thread specification and finished with zinc oxide coating for corrosion resistance in moderate environments. The thin profile allows these locking nuts to fit in space-constrained assemblies where standard full-height nuts would interfere. The nylon insert creates a mechanical lock as the bolt is threaded, effectively dampening vibration without permanent deformation of the fastener itself—allowing multiple installation and removal cycles without degradation of the locking function.

Nylon-insert locking nuts are foundational in motorsports assembly, automotive repairs, equipment maintenance, and any mechanized application where vibration poses a loosening risk. The 10-pack format suits both single-project builders and maintenance technicians stocking standard fasteners. Unlike one-time-use adhesive lock methods, these nuts tolerate repeated assembly and disassembly—a key advantage for service and rebuild scenarios.

This 10-pack provides spare fasteners for assembly kits, replacements in existing equipment, or stock for ongoing maintenance operations requiring proven vibration control without specialized tools or curing time.
