Metallics JWW83PL – Frequently Asked Questions
1) What bolt size does the Metallics JWW83PL flat washer fit?
The JWW83PL is a 1/2 inch USS flat washer, so it is sized for 1/2 inch bolts, all-thread rod, and hex screws. USS pattern means it has the wider outside diameter and the looser hole of the two common flat washer patterns, so it clears a 1/2 inch bolt with a little slop rather than fitting snug.
2) USS or SAE flat washers for 1/2 inch bolts in a strut or channel install?
Go USS when you want the bigger bearing surface. The Metallics JWW83PL is the USS pattern in 1/2 inch, with a larger outside diameter that spreads load over sheet metal, wood, or slotted channel better than an SAE washer of the same bolt size. Pick SAE instead when the washer has to sit inside a counterbore or under a small nut flange where a USS washer would overhang.
3) Do these 1/2 inch flat washers meet an ANSI dimensional standard?
Yes, the JWW83PL 1/2 inch USS flat washer is built to ANSI dimensional standard, which is what lets you mix it with other ANSI-dimensioned 1/2 inch USS washers already on a job without an OD or hole mismatch at the connection.
4) Can I use a Metallics 1/2 inch USS washer under a hanger rod nut on an electrical or mechanical hang?
That is the normal use. A 1/2 inch USS flat washer goes between the nut and the material to spread the clamp load, and it is the standard pairing for 1/2 inch threaded rod used to hang conduit racks, strut, and boxes. The plain steel finish means it belongs indoors and dry; the washer itself is uncoated.
5) How many washers come in a jar of Metallics JWW83PL?
Each jar holds 100 of the 1/2 inch USS plain steel flat washers. The jar pack is the countable shop format, so it suits a service van or a tool room bin where you draw a handful at a time, rather than bulk box quantities for a single large install.
