Metallics JG8N168 – Frequently Asked Questions
1) What thread size and pitch is the Metallics JG8N168 hex nut?
It's a 3/4-10 nut: 3/4 inch nominal diameter with 10 threads per inch, which is the standard UNC coarse pitch for 3/4 inch rod and bolts. If your threaded rod or anchor bolt is 3/4-10, this mates with it. Fine-thread 3/4-16 hardware will not.
2) Is the JG8N168 strong enough to pair with Grade 8 bolts or all-thread?
Yes. The JG8N168 is a Grade 8 hardened steel nut, heat treated to Rockwell C26-34, so it is matched to Grade 8 fasteners and won't be the weak link when you torque a high-strength joint. Dropping a Grade 2 or Grade 5 nut onto a Grade 8 bolt is what strips threads; this avoids that.
3) Will the JG8N168 meet a Buy American or ARRA requirement on a federal job?
No. The JG8N168 is not Buy American compliant and is not ARRA compliant, with multiple countries of origin. On a federally funded project with domestic-content language, specify a domestic-sourced Grade 8 nut instead.
4) What wrench or socket size do I need for these 3/4-10 Grade 8 nuts?
Across the flats the nut measures 1.088 to 1.125 inches, so a 1-1/8 inch wrench or socket is the one to grab. Across the corners it runs 1.240 to 1.299 inches, which matters if you're checking clearance in a tight channel or strut run.
5) How thick is the Metallics JG8N168 nut? I need to know how much rod to leave protruding.
Nut thickness is 41/64 inch (just over 5/8). Leave at least that much thread past your plate or strut plus a thread or two of stick-out so the nut fully engages.
6) Is the zinc finish on these nuts suitable for outdoor or damp locations?
The finish is zinc plating over hardened steel, which handles indoor mechanical rooms, ceiling hangers and strut runs well. It is a plating, not hot-dip galvanizing or stainless, so for direct weather exposure, wet wells, or coastal work you want a hot-dip or stainless nut instead.
7) What standard do these Metallics hex nuts conform to?
Dimensionally they're built to ANSI/ASME B182.2, with steel per AISI 1021-1045. That's the spec to quote if a submittal or engineer's drawing calls out a dimensional standard for the nut.
8) How many nuts come in a jar of JG8N168, and is there a minimum order?
They ship in a jar of 25, and 25 each is the order minimum. Jar weight is 2.87 lbs. Other sizes and quantities can be requested if 25 doesn't match your take-off.
9) Are these hex nuts only for electrical work, or can I use them on mechanical and plumbing jobs?
They're catalogued for the electrical, plumbing, heating and air conditioning trades, so the same 3/4-10 Grade 8 nut works for conduit and cable tray hangers, pipe supports, and HVAC equipment mounting. The grade and thread, not the trade, decide whether it's right for the joint.
