Metallics W119B – Frequently Asked Questions
1) What bolt size does the Metallics W119B fender washer fit?
The W119B is a 3/8 inch fender washer with a 1-1/4 inch outside diameter, so it takes a 3/8 inch bolt or threaded rod. The oversized OD spreads the load well beyond what a standard 3/8 flat washer covers, which is what you want on sheet metal, drywall, strut backing, or any soft or oversized hole.
2) What is the difference between a fender washer and a standard flat washer for 3/8 inch hardware?
Same bore, much bigger face. The W119B pairs a 3/8 inch hole with a 1-1/4 inch outside diameter, where a standard 3/8 flat washer is roughly 7/8 to 1 inch across. Use the fender washer when the hole is oversized, slotted, or in thin or soft material and you need the clamp load spread out. If the hole is tight and the material is solid steel or concrete, a standard flat washer is the cheaper, lower-profile choice.
3) Are Metallics W119B fender washers zinc plated, and can I use them outdoors?
They're zinc plated steel. Zinc plating handles indoor and protected-exterior work and resists corrosion in dry conditions, but it isn't stainless or hot-dip galvanized. For direct weather exposure, wet locations, or coastal air, step up to stainless or hot-dip galvanized washers instead.
4) How many washers come in a box of Metallics W119B?
5,000 washers per box, shipped as a single box pack. That's a bulk contractor quantity, not a hardware-store blister pack, so it suits electrical rough-in crews, MRO cribs, and anyone standardizing 3/8 fender washers across a facility. The full box weighs 75.5 lbs.
5) Will 3/8 fender washers work on 3/8 threaded rod for hanging electrical and HVAC supports?
Yes. A 3/8 inch bore clears 3/8-16 rod, and the 1-1/4 inch face gives a nut or coupling something to bear against on strut, channel, or sheet metal trapeze supports. These are catalogued on the electrical side, which is where they typically get used for rod hangers, box and panel mounting, and strut backing.
6) Are Metallics W119B washers made to a dimensional standard?
They're built to ANSI dimensions, so the 3/8 bore and 1-1/4 outside diameter follow the standard fender washer sizing rather than a proprietary pattern. That matters if you're mixing stock from more than one supplier on the same job and need the faces to match.
