Hex Lock Nut: Insert, Nylon Insert, Grade 2 Steel, Zinc-Plated MPN:R52001652

Hex lock nuts are designed for threaded fastening applications where additional holding power is required, the insert grade 2 steel hexagon lock nut prevents loosening due to vibration or torque back off - the zinc-plated surface enhances corrosion resistance. These threaded fasteners come with a nylon insert located in one end of the hole that grips and holds against mating surface ensuring safe and secure attachment for numerous heavy duty applications, including machinery installation and repair projects, or manufacturing industries requiring stable components that prevent loosening - its wide usage includes automotive assembly lines or construction sites where continuous movement may lead to potential thread slippage on standard nuts without sacrificing grip.
