Metallics JG5WW85 – Frequently Asked Questions
1) What size bolt does the Metallics JG5WW85 flat washer fit?
The JG5WW85 is a 3/4 inch USS flat washer, so it pairs with 3/4 inch diameter bolts, anchors, and all-thread rod. USS pattern means it runs a larger outside diameter and bigger hole than the SAE pattern in the same nominal size, which is what you want when you are spreading load on strut, channel, or wood rather than against a machined surface.
2) Is the JG5WW85 washer grade 5 hardened or just a standard flat washer?
It is a Grade 5 washer, not a plain commercial flat washer. That matters when you are torquing a 3/4 inch Grade 5 or higher bolt down: a soft washer dishes or embeds under the nut and you lose preload. Finish is zinc plated steel for general indoor and protected outdoor electrical work.
3) How many washers come in a jar of Metallics JG5WW85?
50 washers per jar. The jar pack is the reason electrical contractors buy these by the model number rather than loose count, it keeps the 3/4 inch size separated on the truck from the smaller washers in a hardware kit.
4) Can I use these 3/4 inch zinc washers outdoors or in a wet location?
Zinc plated steel is a light corrosion coating, fine for indoor runs, mechanical rooms, and dry or damp protected locations. For direct weather exposure, rooftop strut, coastal air, or anything washed down, step up to hot dip galvanized or stainless 3/4 inch USS washers instead, since zinc plating will eventually rust through at the plated edges.
5) Do I need a flat washer under both the nut and the head on 3/4 inch threaded rod hangers?
For trapeze and strut hangers on 3/4 inch rod, a flat washer like the JG5WW85 goes under every nut that bears on channel, angle, or wood so the nut does not pull through or crush the material. On steel to steel with a proper hole, a washer under the turned element is the usual practice. The JG5WW85 covers the 3/4 inch size only, so size any smaller rod separately.
