Metallics W119V Washers 3/8 X 1-1/4 Fender St-zn (Box 500)

The W119V is a 3/8 inch fender washer, so it goes over 3/8 inch bolts, rods, or threaded rod. The 1-1/4 inch outside diameter is what makes it a fender washer rather than a flat washer: it spreads the clamping load over a much wider area than a standard 3/8 flat washer, which is why it gets used on sheet metal, strut, electrical boxes, and oversized or slotted holes where a regular washer would pull through.

They're zinc plated steel, which gives corrosion resistance for indoor, dry, and light damp work. Zinc plating is not the same as hot dip galvanized or stainless, so for sustained outdoor exposure, wet locations, or coastal air, step up to a stainless or hot dip galvanized fender washer instead.

They ship 500 per box, packaged as a box rather than loose or carded. At 11.65 lbs for the full box, it's a bulk quantity meant for shops doing repeat 3/8 inch hanger and strut work, not a handful for one fixture.

That's the main reason to reach for one. The 1-1/4 inch OD on the W119V bridges slots and oversized holes that a standard 3/8 flat washer would pull straight through, so it's a common pick for hanging conduit, boxes, and equipment off strut or punched metal.

Order Metallics W119V. That's the manufacturer part number for the 3/8 x 1-1/4 zinc plated steel fender washer in the 500 piece box, and it's the only configuration under that number.

Yes, and it's standard practice. A 3/8 fender washer under the nut on 3/8 threaded rod spreads the load across the channel, bracket, or sheet it bears on. For overhead support work, confirm the load rating required by your spec is carried by the rod and anchor; the washer's job here is bearing area, not load rating.
