Metallics JG8WW83 – Frequently Asked Questions
1) Will the Metallics JG8WW83 flat washer work with a 1/2 inch bolt?
Yes. The JG8WW83 is a 1/2 inch USS pattern flat washer, so it pairs with 1/2 inch bolts, all-thread rod, and anchors. USS pattern means a wider outside diameter and a larger hole than the SAE pattern in the same nominal size, which is what you want when you are spreading load on strut, sheet metal, or wood rather than mating a machined surface.
2) Are these hardened washers, or plain mild steel?
Hardened steel. The JG8WW83 is a Grade 8 washer, so it is heat treated to resist being dished or crushed under a high torque bolt. Plain mild steel washers deform under Grade 8 fastener loads and let the joint lose clamp force; that is the whole reason to spec the hardened version.
3) What finish are the Metallics 1/2 inch Grade 8 washers, and can they go outdoors?
They carry a zinc chromate finish over hardened steel. That gives general corrosion protection for indoor and protected exterior work, mechanical rooms, and damp locations. For direct weather exposure or a coastal site, stainless or hot dip galvanized hardware is the usual call.
4) How many washers come in a jar of Metallics JG8WW83?
100 washers per jar. Metallics packs them in a jar rather than a bag, which is what makes them practical on a service van or a shop bench shelf, and the filled jar weighs 3.77 lbs.
5) Do I still need a lock washer if I use these 1/2 inch Grade 8 flat washers?
The JG8WW83 is a flat washer. It spreads the clamp load and protects the surface under the nut or bolt head, but it does not resist loosening on its own. If the assembly sees vibration, add a split lock washer, a serrated flange nut, or a nylon insert lock nut in the same 1/2 inch size.
