Metallics JW115SS – Frequently Asked Questions
1) Will a 5/16 fender washer work with a 5/16 bolt or threaded rod on an electrical strut mount?
The Metallics JW115SS is a 5/16 inch fender washer with a 1-1/4 inch outside diameter, so it slips over 5/16 inch bolts, machine screws, or 5/16-18 threaded rod. The oversized outside diameter spreads the load over a much larger bearing surface than a standard flat washer, which is why it gets used on strut, sheet metal, and thin panel work where a standard washer would pull through.
2) Are the Metallics JW115SS fender washers stainless steel or plated?
Stainless steel, not zinc plated. That matters if you are mounting outdoors, in a damp mechanical room, or anywhere a plated washer would bleed rust onto a finished surface. Pair it with stainless fasteners to avoid mixing metals at the joint.
3) How many fender washers come in a jar of Metallics JW115SS?
100 washers per jar, packed in a screw-top jar rather than a bag or box, so it stays closed in a gang box or on a service truck shelf. The jar weighs 1.46 lbs.
4) Should I use a fender washer or a standard flat washer for mounting a box to drywall or thin sheet metal?
Use the fender washer when the material is thin or soft. A standard 5/16 flat washer has an outside diameter close to the bolt head, so under load it can crush or pull through drywall, thin steel panel, or an oversized hole. The JW115SS fender washer runs 1-1/4 inches across on the same 5/16 bore, which is the larger bearing surface it is built for. For a bolted steel-to-steel connection where the hole is tight, a standard flat washer is the normal choice.
5) Are these washers suitable for plumbing and HVAC work, or electrical only?
The JW115SS is sold for electrical, plumbing, heating and air conditioning work. It is a general-purpose stainless fender washer, so hanging duct strap, mounting a pump bracket, or backing up a conduit support are all in scope.
6) Do Metallics JW115SS fender washers meet ANSI dimensional standards?
Yes, the JW115SS is built to ANSI dimensional standards for the 5/16 x 1-1/4 fender size, so it interchanges with other ANSI-dimensioned 5/16 fender washers already on the job.
