Machine Screw Nut 3/8"-16

This hex nut fits 3/8"-16 machine screws and bolts for general fastening tasks. It is made from Grade 2 steel with a zinc-plated finish for basic corrosion resistance. The hardware suits maintenance, repair and light assembly work where a standard coarse-thread nut is required.

Grade 2 strength limit

Grade 2 steel provides lower tensile strength than higher-grade fasteners, so the nut is not suited for high-stress or critical structural joints. Overtightening can strip threads or deform the nut under heavy loads. Buyers who need higher clamp loads or safety-critical fastening should select a stronger grade.

Zinc-plated corrosion protection

The zinc plating resists rust in dry or mildly damp environments but will degrade faster in salty, acidic or continuously wet conditions. For outdoor, marine or chemical exposure, a different coating or stainless steel is more appropriate.

Questions about this item

Should I pick the 3/8"-16 zinc-plated nut or a different thread size?

Choose the 3/8"-16 nut only when the mating bolt or machine screw has the same 3/8"-16 thread; a different pitch or diameter will not engage properly.

What does the Grade 2 rating mean once the nut is on a bolt?

Grade 2 indicates a standard carbon-steel strength level suitable for general-purpose fastening where high tensile loads are not required.

How does the zinc plating affect corrosion resistance in practice?

The zinc plating provides a sacrificial barrier that slows rust on the steel substrate in typical indoor or mildly damp environments.
