Metallics JW1191SS – Frequently Asked Questions
1) What bolt size does the Metallics JW1191SS fender washer fit?
The JW1191SS is a 3/8 inch fender washer with a 1-1/4 inch outside dimension, so it takes a 3/8 inch bolt, screw, or threaded rod. The wide body is the point: it spreads the load across a much larger bearing surface than a standard 3/8 flat washer, which is what you want on sheet metal, thin panel, or an oversized or slotted hole.
2) Are these 3/8 fender washers stainless, and will they hold up outdoors or near salt air?
They're 316 stainless steel. 316 is the marine grade, so coastal, wash-down, roof-mounted, and chemical-exposure work is where it earns its keep over 304 or plated steel. No coating to chip, so no rust bleed streaking down a finished panel.
3) How many washers come in a jar of Metallics JW1191SS?
100 pieces per jar. It ships as a jar pack rather than a bag, which is the format that survives a job box or a parts shelf without splitting. Jar weight is 1.87 lbs.
4) Can I mix 316 stainless fender washers with galvanized or zinc-plated bolts?
You can, but it isn't good practice. Pairing 316 stainless washers with zinc or galvanized fasteners in a wet location sets up galvanic action and the plated part corrodes first. If you're specifying 316 stainless washers for the corrosion resistance, run stainless bolts and nuts with them so the whole joint matches.
5) Will a 3/8 fender washer work for mounting strut, conduit straps, or an enclosure to a thin panel?
That's exactly the use. A 3/8 fender washer gives you a 1-1/4 inch bearing face, so it keeps a nut or bolt head from pulling through sheet metal or a slotted hole when you're hanging an enclosure, a strap, or a backplate. It's a load-spreading washer, not a locking one, so add a lock washer or a nylon-insert nut if the assembly sees vibration.
6) Should I use a fender washer or a standard flat washer for 3/8 hardware?
Pick by what's under the washer. A standard 3/8 flat washer is enough on structural steel or a properly sized hole in solid material. Go to the 3/8 x 1-1/4 fender washer when the substrate is thin, soft, or the hole is oversized or slotted, because the wider body is what stops the fastener from crushing through or pulling out.
7) Does the Metallics JW1191SS meet a dimensional standard for washers?
The JW1191SS is built to ANSI dimensional standards, so the bore and body size interchange with other ANSI-spec 3/8 fender washers on a submittal or a repair.
