Metallics JW113D – Frequently Asked Questions
1) What bolt size does the Metallics JW113D fender washer fit?
The JW113D is a 1/4 inch fender washer with a 1 inch outside diameter, so it takes a 1/4 inch bolt or screw shank. The oversized 1 inch OD spreads the load far wider than a standard 1/4 inch flat washer, which is why it gets used on sheet metal, panel, and thin-material connections where a standard washer would pull through.
2) Are Metallics JW113D fender washers zinc plated for corrosion resistance?
Yes. The JW113D is steel with a zinc plating. That makes it suitable for dry interior electrical and general fastening work, and it gives some protection in damp conditions, but zinc plated steel is not a stainless substitute for direct outdoor exposure or wet, corrosive environments.
3) Are Metallics JW113D washers made in the USA?
Yes, country of origin on the JW113D fender washer is the United States. That matters for Buy American and domestic-preference line items on government, institutional, and federally funded projects where origin has to be documented on the submittal.
4) Should I use a fender washer or a standard flat washer on strut and sheet metal work?
Use the fender washer when the material under the head is thin or the hole is oversized. The JW113D's 1 inch outside diameter on a 1/4 inch bolt gives roughly four times the bearing diameter of the bolt, which is what you want over slotted strut, sheet metal enclosures, drywall, or an enlarged hole. A standard 1/4 inch flat washer is the right choice when you are bearing on solid steel or a machined surface and only need to protect the finish and distribute a modest load.
5) Can I use these 1/4 inch fender washers for electrical panel and box mounting?
That is the intended use. The JW113D is stocked as electrical fastening hardware, and the wide 1 inch bearing surface on a 1/4 inch fastener is what keeps a bolt head from pulling through the thin sheet steel of a panel, enclosure, or outlet box. Zinc plated steel also keeps it compatible with the plated hardware already in most panel assemblies.
6) Is the Metallics JW113D fender washer built to a dimensional standard?
The JW113D is produced to ANSI dimensional standards, so the 1/4 inch bore and 1 inch outside diameter will interchange with other ANSI-spec 1/4 x 1 fender washers already on the job. Useful when you are topping up a bin rather than starting fresh.
