Hobson NFG8ZC050 1/2" UNC Serrated Hex Flange Nut, Zinc Plated

This page covers one Hobson UNC serrated hex flange nut, size 1/2"; zinc plated finish. A flange nut has a round flange formed on one end, so the nut bears on a wider face than a plain hex nut.

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

Hobson's acronym list defines "serrated" as locking serrations on the bearing face of a bolt or nut (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).

Each item is supplied as a box of 100.

The store title and supplier description say Grade 5, but the part code carries an 8 in the grade position. Because the two disagree, no grade is published here: confirm the grade with Hobson before ordering.

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 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.
