Metallics JG5WW83 – Frequently Asked Questions
1) What bolt size do the Metallics JG5WW83 flat washers fit?
The JG5WW83 is a 7/16 inch USS pattern flat washer, so it goes under 7/16 inch bolts and nuts. USS pattern means a wider outside diameter and larger hole than the SAE pattern in the same nominal size, which is what you want when you are spreading load on wood, sheet metal, or an oversized hole in strut or a panel. If you need a tighter fit against the bolt shank in a machined hole, an SAE pattern washer is the better call.
2) Are these Metallics washers zinc plated for outdoor or damp locations?
They are steel with a zinc plating, which is a general purpose corrosion finish for dry and normally protected indoor work. Zinc plated steel handles damp and occasional exposure but it is not a substitute for hot dip galvanized or stainless in direct weather, wet wells, or corrosive environments. For a rooftop or exterior run, specify galvanized or stainless hardware instead.
3) How many washers come in a jar of the Metallics JG5WW83?
Each jar holds 100 of the 7/16 inch USS flat washers. The jar pack is what makes it useful on a van or a job cart, one container per size rather than loose washers in a bin, and the whole jar weighs 3.53 lbs.
4) What does the G5 in the Metallics 7/16 washer description mean for load?
G5 is the Grade 5 designation, a hardened steel washer rather than a soft low carbon one. That matters when you are torquing a Grade 5 or stronger bolt: a soft washer will dish or cup under the nut and you lose clamp load. Pair these with 7/16 Grade 5 bolted connections in strut, equipment mounting, and hanger work.
5) Is this washer suitable for electrical equipment and strut mounting work?
Yes. The JG5WW83 is stocked as electrical fastener hardware, and a 7/16 USS flat washer is a standard piece for hanging strut, mounting panels and enclosures, and anchor work where the bolt passes through a slotted or oversized hole. The wide USS bearing surface is exactly what a slotted strut channel needs.
6) Where are the Metallics JG5WW83 washers made?
Country of origin is China. For jobs carrying a domestic sourcing requirement such as Buy American on federal or transit work, this part will not satisfy that clause and you will need a domestically produced washer.
7) What is the size of the jar the Metallics washers ship in?
The container measures 3 x 3 x 4.57 inches, so a jar of 100 fits on a standard parts shelf or in a van bin without repacking. Shipping weight of the filled jar is 3.53 lbs.
