Metallics JG8N163L – Frequently Asked Questions
1) What thread size and pitch is the Metallics JG8N163L hex nut?
It's a 1/4-20 nut, so 20 threads per inch on a 1/4 inch coarse thread. That mates with standard 1/4-20 UNC bolts, rod, and screws, which is the common coarse pitch for 1/4 inch fasteners.
2) Will a 1/4-20 Grade 8 nut work with a Grade 5 or Grade 2 bolt?
Yes. The JG8N163L is a Grade 8 hardened steel nut, hardness Rockwell C24-32, so it exceeds the strength of a Grade 5 or Grade 2 bolt and will not be the weak point in the joint. Pairing down in bolt grade is fine mechanically; what you should not do is run a lower-grade nut on a Grade 8 bolt, because the nut strips first.
3) Do these nuts meet a recognized dimensional standard for government or institutional specs?
Dimensions conform to ANSI/ASME B182.2 and the material is AISI 1021 to 1045 steel. The nuts are flagged ARRA compliant and Buy American compliant, with China given as the country of origin, so a federally funded job should confirm which of those provisions governs the contract.
4) Are these zinc plated nuts OK outdoors or in damp locations?
The finish is zinc on hardened steel, which is a general-purpose plating for dry indoor and sheltered use. It handles incidental moisture, but it is not a long-term exterior or wet-location coating. For sustained outdoor exposure, washdown areas, or coastal sites, go to hot-dip galvanized or stainless.
5) How many nuts come in a jar of Metallics JG8N163L?
They ship 50 nuts to a jar, and 50 count is the order minimum, so one jar is the smallest buy. Jar packaging keeps them contained on a service truck or in a parts bin instead of loose in a bag.
6) Will a Grade 8 hex nut hold on vibrating equipment, or do I need a locknut?
A plain Grade 8 hex nut like the JG8N163L carries the load but has no locking feature, so on equipment that vibrates you pair it with a lock washer, a jam nut, or thread locker, or switch to a nylon-insert or all-metal prevailing-torque locknut. Grade 8 rates the strength, not the resistance to backing off.
7) Can I get this 1/4-20 Grade 8 nut in other sizes or larger quantities?
Yes, the JG8N series is offered in other sizes and pack quantities by request, so if you are standardizing a shop or a maintenance crib on one grade across several diameters, ask rather than buying a single jar size.
