Hobson NC10ZFM10 M10 Metric Fine HCL Cone Lock Nut, Class 10, Zinc Plated

This page lists 5 sizes of the Hobson metric fine HCL cone lock nut: M10 to M20; zinc plated finish. The supplier names this style an HCL cone lock nut. The supplier file does not describe the locking action or give nut dimensions, so none are published here.

The supplier names these nuts Class 10. The Hobson guides publish strength tables for bolts, not nuts, so no nut strength figure is published here.

Hobson's acronym list defines ZP as zinc, usually referencing zinc plating (zinc with clear chromate) (manufacturer-stated).

The pitch shown for each size is the pitch printed in the Hobson stock list where the part appears there, and otherwise the single fine pitch the Hobson thread table lists for that diameter (manufacturer-stated).

The April 2011 Hobson High Tensile Stock List prints 4 of these 5 items under a heading that names DIN 980; the other sizes are not printed in that list, so no standard is published for them (manufacturer-stated).

Pack quantity is shown for each item in the table.

Common specifications

Key specifications

Pack weights are as printed in the Hobson High Tensile Stock List, April 2011 (manufacturer-stated); a dash means the part is not printed in that list.

Selecting the right option

Choose the thread form first: the nut and its bolt or stud must match in thread form, diameter and pitch. The thread pitch matters as much as the diameter on a fine pitch nut, so check both. The Hobson spanner chart does not list this nut style, so the across-flats size is not published here.
