Hobson NN08ZCM30 M30 Nyloc Insert Lock Nut, Class 8, Zinc

This page covers one Hobson nyloc insert lock nut, size M30; zinc finish. A nylon insert lock nut carries a nylon ring in one end; the bolt or stud threads through the ring as the nut is tightened.

The supplier names these nuts Class 8. The Hobson guides publish strength tables for bolts, not nuts, so no nut strength figure is published here.

In its assembled kits the Hobson stock list pairs Class 8.8 bolts with Class 8 nuts (manufacturer-stated).

The supplier lists the finish as zinc.

The pitch shown for each size is the coarse pitch from the Hobson thread table (manufacturer-stated).

Each item is supplied as a box of 25.

Key specifications

Selecting the right option

Choose the thread form first: the nut and its bolt or stud must match in thread form, diameter and pitch. Sizes are the nominal diameter in millimetres; compare the pitch in the table with your bolt. The Hobson spanner chart does not list this nut style, so the across-flats size is not published here.
