Hobson AXHC05ZCM06 M6 x 18mm Metric Hex Coupler Nut, Class 5, Zinc Plated

There are 5 sizes of the Hobson metric hex coupler nut: M6 to M36; zinc plated finish. A hex coupling nut is a long hex nut used to join two threaded rods or studs end to end.

The supplier names these nuts Class 5. 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).

Pack quantity is shown for each item in the table.

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 second figure in each size (for example 50mm in M16 x 50mm) is the nut length; choose it to suit the rods you are joining. The Hobson spanner chart does not list this nut style, so the across-flats size is not published here.
