Metallics JWW86 – Frequently Asked Questions
1) What bolt size does the Metallics JWW86 flat washer fit?
The JWW86 is a 7/8 inch USS flat washer, so it is sized for 7/8 inch diameter bolts, rods, or anchors. USS pattern means it has a wider outside diameter and larger bore than the SAE pattern in the same nominal size, which is what you want when you are spreading load across a strut, channel, or wood member rather than seating against machined steel.
2) Can I use a 7/8 USS flat washer where the drawing calls for an SAE washer?
Not interchangeably. The JWW86 is the USS pattern, which has a larger outside diameter and bore than a 7/8 SAE washer. If the spec calls for SAE, the USS washer may overhang a machined face or let the bolt shift more than the detail allows. Where the callout is just for load spreading over a soft or oversized hole, the USS pattern is the one you want.
3) Are the Metallics 7/8 inch USS washers plated for corrosion resistance?
They are zinc plated steel. That is a standard indoor and protected-exterior finish, fine for electrical rack and strut work, mechanical rooms, and general building fastening. For continuous wet exposure, direct weather, or coastal sites, step up to hot dip galvanized or stainless instead.
4) How many washers come in a jar of Metallics JWW86?
One jar holds 100 pieces of the 7/8 inch USS flat washer. The jar pack is the shop-bin format, so it is a single unit to order and stays organized on a van shelf or a bench rather than loose in a bag.
5) Is the Metallics JWW86 washer made to a recognized dimensional standard?
Yes, it is built to the ANSI dimensional standard for 7/8 inch USS flat washers, which is what lets you substitute it into a job that specifies a 7/8 USS washer without checking the bore and OD piece by piece.
6) What is the Metallics part number to order for 7/8 inch zinc plated USS flat washers?
Order Metallics JWW86. That number covers the 7/8 inch USS flat washer in zinc plated steel, 100 pieces to the jar, and it is the only configuration the part number carries, so there is no finish or pack option to specify.
