Hobson NNG8ZC100 1" UNC Nyloc Hex Nut, Grade 8, Zinc Plated

A nyloc nut is a hex nut with a nylon ring fitted in its top face. The nylon ring is the locking feature of the nut. This page lists 16 Hobson UNC nyloc hex nuts (UNC 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 IFI100NE 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 UNC as Unified National Coarse 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).

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. Check the supplier details if your application has a temperature or chemical limit, because this page gives no limits for the nylon ring. 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.
