Build vibration-resistant assemblies with 7/16-14 18-8 Stainless Steel Nylon Insert Hex Lock Nuts (Qty 25). The UNC 14 TPI coarse thread installs quickly and grips securely, while the nylon insert (nyloc) provides prevailing torque to resist loosening under vibration. 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 7/16-14 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 during high-torque installs.
