Metallics WW832M – Frequently Asked Questions
1) What size bolt does the Metallics WW832M flat washer fit?
The WW832M is a 1/2 inch USS flat washer, so it is sized for 1/2 inch bolts, threaded rod, and anchors. USS pattern means a larger outside diameter and bigger hole than the SAE pattern of the same nominal size, which is what you want when you are spreading load on strut, wood, or slotted steel rather than seating against a machined surface.
2) Can I use these USS washers with 1/2 inch strut and threaded rod for conduit supports?
Yes. A 1/2 inch USS flat washer is the standard piece for bearing a nut against strut, channel, or a slotted fitting where the hole is oversized. The wide USS outside diameter bridges the slot instead of pulling through it. For 1/2 inch all thread drops carrying conduit racks, this is the pattern most electrical specs call out.
3) Are these Metallics 1/2 inch washers plated for corrosion resistance?
They are zinc plated steel. That plating handles dry interior work, indoor electrical rooms, and normally protected mechanical spaces. For sustained wet or exterior exposure, step up to hot dip galvanized or stainless of the same 1/2 inch USS pattern.
4) How many washers come in a box of Metallics WW832M?
Each box holds 2,000 pieces of the 1/2 inch USS flat washer. That is bulk quantity aimed at a contractor hanging strut, all thread, and conduit racks across a whole job, not a counter pack. If you only need a few dozen, a small bag quantity is the better buy.
5) What is the difference between a USS and an SAE flat washer in 1/2 inch?
Same nominal bolt size, different proportions. USS, which is what the WW832M is, has the wider outside diameter and the looser hole, so it spreads clamp load over softer or slotted material and tolerates sloppy hole alignment. SAE is narrower with a tighter hole, used where the washer has to sit inside a small counterbore or against a finished machine surface. If a drawing just says flat washer on structural or strut work, USS is normally what is meant.
6) Is the Metallics WW832M made to a recognized dimensional standard?
It is built to the ANSI dimensional standard for the 1/2 inch USS flat washer pattern, so the outside diameter, hole, and thickness interchange with any other ANSI pattern USS washer of that size from another supplier. That matters for an MRO stockroom standardizing one washer bin across multiple trades.
7) How heavy is a full box of these 1/2 inch flat washers?
A full box runs 64 lbs, measuring 9 x 9 x 6.13 inches. Worth knowing before someone carries it up a ladder or loads a cart: it is a two hand lift, and stacking several on a shelf is a real load.
