Bremick NHG5ZF037 3/8" UNF Hex Nut, Grade 5, Zinc

A hex nut is the standard six-sided nut. It is turned with a spanner or socket onto a bolt, stud or threaded rod of the same thread form, diameter and pitch. This page covers one Bremick UNF hex nut (UNF thread, Grade 5, zinc finish), size 3/8", supplied as a box of 50.

The maker defines UNF as Unified National Fine Thread, and TPI as threads per inch (manufacturer-stated). Threads per inch come from the maker's thread table, for the sizes it lists (manufacturer-stated).

The maker defines Grade as the imperial strength level of a screw or nut, for example Grade 2, Grade 5 or Grade 8 (manufacturer-stated). On the maker's class vs grade chart, Grade 5 is listed as high tensile, alongside metric Class 8.8 (manufacturer-stated).

The maker's strength tables cover bolts and screws, not nuts, so no strength figure is published for these nuts.

This item is not in the published stock list, so no standard, spanner size or pack weight is published for it.

Key specifications

Selecting the right option

Match the nut to the bolt, stud or rod: thread form, diameter and pitch must all agree. Sizes are nominal thread diameters in inches. Compare the threads per inch with your bolt. If the joint is load-critical, confirm the nut and bolt pairing with your specification.
