Metallics JSSW20 – Frequently Asked Questions
1) Are these Metallics 7/16 washers stainless steel or plated?
Stainless steel, not zinc-plated carbon. That matters for exterior strut runs, rooftop equipment, wet rooms and coastal work where a plated washer rusts and stains the surface under it. Pair them with stainless bolts and nuts so you are not mixing metals in the same joint.
2) How many washers come in a jar of Metallics JSSW20?
They ship 100 to a jar. The jar is the pack unit, so a single order gets you a hundred 7/16 stainless flat washers rather than a loose count, which is how most electrical and maintenance crews want them stocked on the truck.
3) Is a flat washer like this the right choice, or do I need a lock washer?
The JSSW20 is a flat washer, so its job is to spread load and protect the surface under the nut or bolt head. It does not resist loosening from vibration. On equipment that vibrates, use the flat washer against the material and add a split lock washer or a nylon-insert lock nut on top of it.
4) Will a 7/16 stainless flat washer work for bolting steel to steel?
Metal to metal is the stated application for these washers. The 59/64 inch outside diameter is a standard narrow bearing surface, fine on steel plate, angle, and strut where the material itself carries the load. For bolting through wood, sheet metal, or anything soft, step up to a fender washer with a much larger outside diameter instead.
5) Can I order 7/16 stainless flat washers by part number for a submittal?
Order them as Metallics JSSW20. One model, one configuration: 7/16 flat, stainless, 100 per jar. Country of origin is listed as multiple, which is worth noting if your spec requires a single declared origin.
6) What does a jar of 100 Metallics JSSW20 washers weigh and how big is the container?
The jar comes in at 0.77 lbs and measures 3 x 3 x 2.15 inches, so it drops into a van bin or a parts drawer without taking a shelf.
