Metallics JG8N1881 Nuts 1-14 G8 Hx Nut St-zn (Jar 25)

It's a 1 inch nut with 14 threads per inch, so 1-14 UNF (fine thread). That matters: a 1 inch coarse rod or bolt is 1-8 UNC and will not thread into this nut. Confirm your rod or bolt is fine pitch before ordering.

Grade 8, hardened steel, tested at Rockwell C26-34. That puts it in the right class for Grade 8 bolting in structural and high-tension connections, where a lower grade nut would strip before the bolt reached full torque.

Both the Buy American and ARRA compliance flags are marked C on the JG8N1881, with country of origin China. Institutional and government buyers working to a domestic-content clause should read those two flags together before submitting.

Across the flats the nut measures 1.450 to 1.500 inches, so a 1-1/2 inch wrench or socket is the size to bring. Across the corners it runs 1.653 to 1.732 inches, which is the clearance you need in a tight pocket or inside a strut channel.

Dimensions follow ANSI/ASME B182.2, and the steel is AISI 1021-1045. If your drawing calls out a B18.2.2 heavy or finished hex nut in Grade 8, those are the two callouts a submittal usually asks for.

They ship 25 to a jar, and 25 count is the order minimum, so the jar is the smallest unit. Other sizes and quantities are available by request if you need a different pitch or a larger count for a repeat job.

The finish is zinc plating over hardened steel, which handles indoor and sheltered conditions and short term weather exposure. For sustained wet, coastal, or buried service, zinc plating is not the finish to specify; hot dip galvanized or stainless is the usual move there. Note that galvanized rod needs an oversized tapped nut, so keep plating consistent across the joint.

6.89 lbs for the jar of 25. The jar itself is listed at 7.25 in. high and 4.5 by 4.5 in., which is worth knowing if you're stocking a service van drawer or a shop bin.
