Build vibration-resistant assemblies with 8-32 18-8 Stainless Steel Nylon Insert Hex Lock Nuts (Qty 50). The UNC 32 TPI coarse thread installs quickly and holds strong, while the nylon insert (nyloc) maintains prevailing torque to resist loosening in high-vibration environments. Made from 18-8 (304) stainless steel, these lock nuts deliver excellent corrosion resistance for automotive, marine, outdoor, and industrial use.
Standard hex flats ensure easy wrench access and consistent torque. Pair with matching 8-32 stainless bolts or studs for a long-lasting, rust-resistant connection. Tip: with stainless-on-stainless joints, a dab of anti-seize helps reduce galling at higher torque.
Terms of Service: 60-day money-back with free return shipping.
