Product Identity

This MIDWEST FASTENER CORP 06820 Hex Nut pack contains twenty zinc-plated steel Grade 5 nuts with a 3/4"-10 thread specification. They are designed to secure machine screws and bolts in automotive, industrial, and general repair applications. The Grade 5 rating provides medium tensile strength suitable for standard fastening tasks. The bulk quantity supports maintenance shops and ongoing project needs.

Suitability

These nuts suit mechanics, fabricators, and maintenance teams needing reliable Grade 5 fasteners in a convenient twenty-count package. The zinc plating offers corrosion resistance for typical indoor and sheltered outdoor use. Buyers requiring stainless steel for marine environments, higher-grade hardware for structural loads, or fine-thread variants for precision assemblies should look at alternative product lines.

Deciding Specification

The critical specification is the 3/4"-10 coarse thread pitch, which must match the bolt or stud exactly for proper engagement. Grade 5 steel determines the mechanical strength limit for the joint design. Confirm thread compatibility before purchase to avoid fitment issues. The twenty-piece pack quantity supports volume requirements for repeated use.

Questions about this item

What thread standard does the 3/4"-10 hex nut follow and what does the 10 indicate?

The 3/4"-10 hex nut uses Unified Coarse thread; the 10 denotes 10 threads per inch on a three-quarter inch major diameter.

What wrench size fits the 3/4" hex nut for installation?

A 1-1/8 inch wrench or socket engages the flats of a 3/4" hex nut for proper tightening.

How are these Grade 5 zinc-plated hex nuts installed and what common error should be avoided?

Thread each nut onto a Grade 5 bolt by hand, then torque with a calibrated wrench; avoid over-tightening which can strip the coarse threads.
