Hobson NHG8ZF100F 1" UNF Hex Nut, Grade 8, Zinc Plated

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 lists 13 Hobson UNF hex nuts (UNF thread, Grade 8, zinc plated finish): 1/4" to 2".

Hobson defines Gr as the imperial grade-strength level of a screw or nut, for example Grade 2, Grade 5 or Grade 8 (manufacturer-stated).

The Hobson strength tables cover bolts, not nuts, so no strength figures are published for these nuts.

The Hobson High Tensile Stock List, April 2011, names AS 2465 in the heading for the nuts it lists here (manufacturer-stated). The other items are not in that catalogue, so no standard is published for them.

Hobson defines UNF as Unified National Fine Thread and TPI as threads per inch (manufacturer-stated).

Threads per inch come from the Hobson thread table, for the sizes it lists (manufacturer-stated).

Spanner sizes (A/F) come from the Hobson spanner chart and are shown only for items whose catalogue heading names the standard of a chart column (manufacturer-stated).

Catalogue pack weights are from the Hobson High Tensile Stock List, April 2011, and are shown only where the catalogue pack quantity matches the pack quantity here (manufacturer-stated).

The pack, box or bag quantity for each size is shown in the table.

Common specifications

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. For the items with a spanner size shown, the size is from the Hobson spanner chart (manufacturer-stated). Choose the class or grade to suit the bolt you are fastening, and confirm the pairing with your specification if the joint is load-critical.
