Metallics JSSW131 – Frequently Asked Questions
1) What bolt size do the Metallics JSSW131 flat washers fit?
They are 5/16 inch flat washers, so they go under 5/16 inch bolt heads and nuts. Each jar holds 100 pieces, which is the quantity most crews want on a strut or channel job rather than a loose handful.
2) Are the JSSW131 washers stainless steel or plated steel?
Stainless steel, not zinc-plated carbon steel. That matters for exterior conduit runs, rooftop equipment, wash-down areas and anywhere a plated washer would rust-streak the surface it is bolted to.
3) Can I use these 5/16 stainless flat washers for metal-to-metal connections on equipment and channel?
Yes. The application for the JSSW131 washer is metal to metal, so it is intended to spread load between metal parts, for example strut and channel hardware, enclosure and equipment mounting, and bonding hardware where a 5/16 bolt is used.
4) Will a 5/16 stainless flat washer work with a stainless bolt to avoid mixed metals?
It will. Pairing the stainless JSSW131 washer with stainless bolts and nuts keeps the fastener stack one material, which is the usual practice outdoors to avoid galvanic corrosion between a plated washer and a stainless bolt.
5) How many 5/16 washers come in a jar of Metallics JSSW131, and how much does the jar weigh?
One hundred washers per jar, and the packed jar weighs 0.5 lbs. The jar format keeps them from scattering in a gang box or on a service truck.
6) Is this a flat washer or a lock washer?
Flat, not split-ring or tooth lock. A flat washer spreads bearing load and protects the surface; if you need vibration resistance on the same 5/16 bolt, you would add a separate stainless lock washer or a nylon-insert nut.
