Metallics JSSW181 – Frequently Asked Questions
1) Are Metallics JSSW181 washers stainless steel, and can they be used outdoors?
Stainless steel is the material, which is why they hold up in damp and outdoor settings where plain or zinc plated washers rust. Common uses are exterior strut and conduit support, rooftop equipment, and wash-down areas.
2) How many washers come in a jar of Metallics JSSW181?
Each jar holds 100 pieces of the 7/16 inch stainless flat washer. The jar pack is sized for a service van or an MRO shelf rather than a single install, so one jar covers repeat work without reordering.
3) Should I use a flat washer or a lock washer with 7/16 bolts?
They do different jobs and are often used together. The JSSW181 flat washer spreads load and protects the mating surface; a split or tooth lock washer resists the nut backing off under vibration. On equipment that vibrates, a common stack is the flat washer against the material and the lock washer under the nut. If all you need is bearing area on strut or sheet metal, the flat washer alone is the right call.
4) What does a 7/16 flat washer actually do in an electrical install?
A flat washer spreads the clamping load of the nut or bolt head over a wider area, so it keeps the fastener from pulling through sheet metal, strut, or an enclosure wall and protects the surface from being chewed up as the nut turns. The JSSW181 is the 7/16 inch stainless version, used with 7/16 inch hardware on hangers, brackets, and support steel.
5) How much does a jar of 100 Metallics 7/16 stainless flat washers weigh, and how big is the jar?
The packed jar weighs 1.3 lbs and measures 3 x 2.7 x 3 inches. That matters if you are stocking a truck bin or a parts drawer and need to know what footprint it takes.
6) Where are Metallics JSSW181 washers made?
Country of origin is China. Worth checking against your spec if you are buying for a government or institutional job with domestic sourcing requirements.
