Hex Nut · 1/4 in-20 · Grade 5 zinc-coated steel · Finished pattern · Fasteners HN5Z1420

What this product is for

This finished hex nut is used to secure 1/4 in-20 coarse-thread bolts or machine screws in general fastening applications. The zinc-coated steel construction is commonly selected for indoor use and dry-location assembly work where a standard Grade 5 nut is required.

Use for

Use for equipment assembly, electrical support hardware, brackets, guards, panels, maintenance work, and general shop fastening. It is typically paired with a matching 1/4 in-20 bolt and flat washer where a standard-height hex nut is preferred.

Avoid for

Avoid using this nut where stainless steel, hot-dip galvanized, prevailing-torque lock nuts, or vibration-resistant locking hardware is required. Do not use it as a substitute for engineered fastening requirements where project specifications call for a different grade, finish, or locking method.

Best for

Best for contractors and maintenance teams needing a common inch-size finished hex nut for replacement stock, field repairs, and routine assembly. It suits applications where 1/4 in-20 coarse thread is already standard on the equipment or hardware being serviced.

Installed in

Typically installed in control panel hardware, strut-mounted accessories, machine guards, brackets, fabricated assemblies, and general building maintenance hardware. For electrical and mechanical work, verify clearance for a standard hex pattern before ordering.

Why this product exists

This product provides a standard reusable nut for inch-thread fastening systems. Compared with specialty lock nuts or flange nuts, a finished hex nut is the common choice when you need straightforward assembly, serviceability, and easy wrench access.

Compared with similar products

Compared with jam nuts, this finished hex nut has a standard height for more thread engagement. Compared with lock nuts, it does not provide a built-in locking feature. Zinc-coated steel is typically more economical than stainless steel, but it is generally better suited to dry or mildly corrosive environments.

Typical trade guidance: match the nut to the exact bolt thread and grade family where required by the application. Actual performance depends on joint design, torque, loading, environment, and local code or engineering requirements.
