Product identity

This pack contains five Grade 8 steel hex nuts with a 3/4"-16 thread pitch and a zinc yellow finish. They are designed to secure the threaded portion of machine screws and bolts in high-strength fastening applications.

Who it suits

Mechanics and fabricators who need a small quantity of high-tensile fasteners for structural or automotive assemblies will find this pack convenient. Builders who require a different thread pitch, a larger quantity, or stainless steel corrosion resistance should look at other options.

Installation notes

Each nut threads onto a matching 3/4"-16 bolt or stud by hand and is tightened with a standard wrench or socket. The main issue is cross-threading if the fastener is not started straight, which can damage both the nut and the bolt threads.

Questions about this item

What bolt thread must I already have for the 3/4"-16 hex nuts to work?

You need bolts or studs with a 3/4"-16 thread pitch so the nuts engage correctly.

Can I mix these Grade 8 zinc yellow nuts with lower-grade fasteners on the same joint?

Using lower-grade bolts reduces the joint strength to the bolt rating; match Grade 8 hardware for full capacity.

How do I confirm the nuts are properly tightened after installation?

Torque the assembly to the Grade 8 specification for 3/4"-16 threads and verify the nut faces sit flush against the joint.
