Metallics JW1271SS – Frequently Asked Questions
1) What size bolt does the Metallics JW1271SS fender washer fit?
The JW1271SS is a 3/8 inch fender washer, so it goes over a 3/8 inch bolt or threaded rod. The 1 inch outside diameter is what makes it a fender washer rather than a flat washer: you get a much wider bearing surface to spread load over sheet metal, drywall, strut backing, or an oversized hole.
2) Are these Metallics 3/8 fender washers stainless steel or plated?
Solid stainless steel, not zinc plated carbon steel. That matters for outdoor runs, rooftop equipment, wash-down areas, and coastal jobs where a plated washer will rust and streak the surface it sits on. If your fastener is stainless, match it here so you are not putting dissimilar metals together.
3) How many washers come in a jar of Metallics JW1271SS?
100 pieces per jar, packed in a jar rather than a loose bag, so they stay sorted on the truck or the bench. Total shipping weight for the jar is 0.9 lbs.
4) Should I use a fender washer or a standard flat washer for mounting electrical boxes and strut?
Use the fender washer when the material under the fastener is thin or the hole is oversized, which is most sheet metal box, enclosure, and unistrut backing work. The 1 inch OD on a 3/8 inch bolt spreads clamp load far enough that the head will not pull through. A standard 3/8 flat washer has a much smaller OD and is the right call when you are bolting into solid steel or another washer-faced nut and only need bearing under the head.
5) What is the exact part number and brand for these 3/8 x 1 stainless fender washers?
Metallics part number JW1271SS. That single number covers the complete jar of 100 stainless 3/8 x 1 fender washers, so it is what to quote on a purchase order or a counter pickup.
6) Will a jar of 100 fender washers fit in a van bin or tool drawer?
The jar measures 3 x 3 x 2.15 inches, so it drops into a standard parts bin or a tool bag pocket without decanting. Small enough to keep several sizes on the truck at once.
