Hobson NCGCZF043 7/16" UNF HCL Cone Locking Nut, Grade C, Zinc Plated
Available
This page lists 17 items of the Hobson UNF HCL cone locking nut: 1/4" to 2"; 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.
Grade C is the supplier's name for these nuts. It is not defined in the Hobson guides, so no strength level is published.
Hobson's acronym list defines ZP as zinc, usually referencing zinc plating (zinc with clear chromate) (manufacturer-stated).
The threads per inch shown are from the Hobson thread table, which defines TPI as threads per inch, for the sizes the table lists (manufacturer-stated).

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 nominal diameters in inches; compare the threads per inch with your bolt. The Hobson spanner chart does not list this nut style, so the across-flats size is not published here.
