Hobson NC10ZCM06 M6 Metric HCL Cone Locking Hex Nut, Class 10, Zinc Plated

There are 14 sizes of the Hobson metric HCL cone locking hex nut: M6 to M48; zinc plated finish. The supplier names this style an HCL cone lock nut. The published product details do not describe the locking action or give nut dimensions, so none are published.

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.

ZP means zinc, usually referencing zinc plating (zinc with clear chromate) (manufacturer-stated).

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

The April 2011 Hobson High Tensile Stock List prints 8 of these 14 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. 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.
