Metallics WW83M – Frequently Asked Questions
1) What size bolt does the Metallics WW83M flat washer fit?
The WW83M is a 1/2 inch USS flat washer, so it is sized for 1/2 inch bolts, all-thread rod, anchors and studs. USS pattern means the outside diameter and hole are the wider of the two common flat washer patterns, which spreads load better on wood, sheet steel and slotted strut than an SAE washer of the same nominal size.
2) Are Metallics WW83M washers zinc plated for damp or outdoor use?
They are zinc plated steel, which handles indoor electrical work, mechanical rooms and covered exterior conditions. Zinc plating is a sacrificial coating, not stainless, so for continuous wet, coastal or corrosive-chemical exposure step up to stainless or hot dip galvanized instead.
3) How many washers come in a box of Metallics WW83M?
One box holds 1,000 pieces of the 1/2 inch USS flat washer, packed as a box rather than a bag or carded pack. That is a bulk quantity meant for stocking a truck or a shop bin on conduit hanging, strut and rod jobs, not a count-out for a single fixture.
4) Should I use a USS or SAE flat washer on 1/2 inch threaded rod?
For 1/2 inch rod hanging conduit, strut or trapeze supports, the USS washer like the WW83M is the usual pick because its larger outside diameter bridges strut slots and oversized holes. An SAE 1/2 inch washer has a tighter hole and smaller OD, which is what you want under a bolt head on a machined surface or where clearance is tight. Same bolt size, different bearing area.
5) How much does a box of 1,000 Metallics 1/2 inch flat washers weigh?
A full box runs 38.65 lbs, with box dimensions of 7.25 x 6.25 x 6 inches. Worth knowing before you send a helper up a ladder or load a job cart with several boxes.
6) Is the Metallics WW83M washer made to a dimensional standard?
It is an ANSI dimensional washer in the 1/2 inch USS pattern, so hole size and outside diameter follow the standard pattern rather than a proprietary one. That matters on spec work where a submittal calls out a standard flat washer under nuts and bolt heads.
