Metallics JSSW781 – Frequently Asked Questions
1) What bolt size do the Metallics JSSW781 flat washers fit?
The JSSW781 is a 7/8 inch flat washer, so it is sized for 7/8 inch bolts, rod, or threaded studs. Use it under the nut or bolt head to spread load and protect the surface on strut, panel, and equipment mounting.
2) Are the Metallics JSSW781 washers stainless steel or plated steel?
Stainless steel, not zinc-plated carbon steel. That matters for outdoor runs, wet wells, wash-down areas, and coastal sites where a plated washer will bleed rust and stain the substrate. It also pairs correctly with stainless hardware, avoiding the mixed-metal corrosion you get from plated washers on stainless bolts.
3) How many washers come in a jar of Metallics JSSW781?
100 washers per jar. The jar pack keeps loose 7/8 washers contained on a service truck or MRO shelf instead of spilling through a bag, and 100 pieces is a stocking quantity for a crew doing repeat strut or anchor work rather than a one-off repair.
4) Will a 7/8 flat washer work as a lock washer to keep a bolt from backing out?
No. A flat washer like the JSSW781 distributes clamp load and protects the mating surface; it does not provide any anti-vibration locking. If the joint sees vibration you need a split lock washer, a serrated flange nut, or a nylon-insert lock nut in the same 7/8 size, used along with the flat washer, not instead of it.
5) How much does a jar of 100 Metallics 7/8 stainless flat washers weigh and how big is the container?
The jar weighs 7.25 lbs and measures 5.75 x 3.5 x 3.5 inches. Worth knowing if you are loading several jars into a van bin or allocating shelf space in a parts room.
6) Is the Metallics JSSW781 washer made to a standard dimensional spec?
It is an ANSI-dimensioned 7/8 flat washer, so the outside diameter and thickness follow the standard pattern rather than a proprietary one. That means it interchanges with other ANSI 7/8 flat washers already on the job.
7) Where is the Metallics JSSW781 washer manufactured?
Country of origin is China. Useful if your project carries domestic-sourcing requirements on fasteners, since this one will not satisfy a Buy American clause.
