This ARP kit contains 5/16-24 stainless steel fine nyloc hex nuts intended for secure threaded fastening where a nylon-insert locking nut is required. The stainless steel construction offers corrosion resistance appropriate for exposed or treated fastener locations. The fine thread specification and hex form make these nuts suitable for assemblies using 5/16-24 hardware where a locking insert is preferred.
