ALLSTAR PERFORMANCE ALL16025-10 Thin Nylon Insert Lock Nuts, 5/8-11 Thread, Zinc-Plated Steel, 10-Pack

Secure threaded assemblies with ALLSTAR PERFORMANCE ALL16025-10 thin nylon insert lock nuts. Designed for applications using 5/8-11 inch threads, these hex-head nuts feature a nylon insert that helps resist loosening caused by vibration and movement. Their thin profile is useful where available thread length or clearance is limited, while the hex design supports straightforward installation with standard tools.
Manufactured from steel and finished with zinc oxide, these locking nuts provide dependable strength and corrosion resistance for automotive, racing, fabrication, and general mechanical projects. The zinc finish helps protect the fastener surface during handling and use, while the steel construction delivers reliable clamping performance when properly installed. The nylon insert creates additional thread resistance without requiring a separate locking washer in many applications.
This 10-piece set is a practical choice for repairs, upgrades, replacement hardware, and shop inventory. Each ALLSTAR PERFORMANCE ALL16025-10 nut is made for compatible 5/8-11 inch threaded fasteners and should be matched with suitable bolts or studs for the intended application. Confirm thread compatibility and tightening requirements before installation. These nuts are not listed as air-restricted or truck-freight-only items, making them convenient for common automotive and workshop use.
