Metallics W117B – Frequently Asked Questions
1) What size bolt does the Metallics W117B fender washer fit?
The W117B is a 3/8 inch fender washer with a 1-1/2 inch outside diameter. It drops over any 3/8 inch bolt, lag, or threaded rod, and the wide 1-1/2 inch OD spreads the load far beyond what a standard 3/8 flat washer covers, which is the point of a fender washer on sheet metal, drywall, or soft material.
2) Why use a fender washer instead of a standard flat washer on a 3/8 bolt?
A standard 3/8 flat washer has an OD under an inch and bears on a small ring of material. The W117B's 1-1/2 inch OD spreads the clamp load over a much larger area, so it is what you reach for anchoring strut, hanging boxes, or bolting through sheet metal, gypsum, plywood, or an oversized or slotted hole where a small washer would pull through or dimple the surface. Same 3/8 bore, far more bearing surface.
3) Are these Metallics washers zinc plated for damp or outdoor use?
Material is zinc plated steel. That handles indoor electrical work, damp interior locations, and protected exterior runs. For direct weather exposure, salt, or a wet corrosive environment, step up to stainless rather than relying on zinc plating.
4) How many washers come in a box of Metallics W117B?
They ship 2,500 per box, packed as a single box. That is a stocking quantity for a shop or a service truck crib, not a job-pack of a few dozen, so plan on it as bin stock across multiple jobs.
5) Can I use these washers with 3/8 inch threaded rod for hanging conduit or strut?
Yes. The 3/8 bore clears 3/8-16 rod, so the washer slides over the rod and bears against a nut. On trapeze hangers, strut, or channel where the hole is oversized, the 1-1/2 inch OD gives the nut something to seat on. Steel zinc construction keeps it in line with standard zinc plated rod and nuts in the same assembly.
6) How heavy is a full box of 2,500 Metallics W117B fender washers?
A full box runs 61.25 lbs, with box dimensions of 9 x 9 x 6.13 inches. Worth knowing before you put it on a shelf or carry it up a ladder, and worth knowing if you are spec'ing shipping on a multi-box order.
7) Are Metallics W117B washers made to ANSI dimensions?
The W117B is listed to ANSI. For a procurement spec that calls out dimensionally standard fasteners, the 3/8 x 1-1/2 fender washer in zinc plated steel is the right line item to match.
