Nylon-Insert Wing Locknuts

Name: Nylon-Insert Wing Locknuts

Material: Carbon Steel+Nylon

Size: M4, M5, M6, M8, M10&Inch #8-32, #10-24, #10-32, 1/4-20", 1/4-28", 5/16-18", 5/18-24, 3/8-16

Surface treatment: environmental protection color zinc, environmental protection blue zinc, zinc-nickel alloy, black zinc, yellow zinc

These wing nuts have a nylon insert that grips threads to resist loosening. The wings provide more leverage for greater torque while tightening than knurled-head thumb nuts. Made from zinc alloy, they resist corrosion in wet environments.
