Metallics JSSW151 – Frequently Asked Questions
1) Are these washers stainless steel, and can I use them outdoors or in damp locations?
The JSSW151 washers are stainless steel, which is what you want for exterior strut runs, rooftop equipment, wet locations and anywhere galvanized would eventually bleed rust. Pair them with stainless bolts and nuts so you are not mixing metals at the joint.
2) How many 1/2 inch stainless flat washers come in a jar of Metallics JSSW151?
One hundred washers, packed in a jar rather than a loose bag, so the count stays intact on a service truck or a bench. Net weight of the jar is 1.62 lbs.
3) What is a flat washer like this actually for on an electrical install?
It spreads the clamping load of the bolt head or nut over a wider area so the fastener does not dig into or deform the material it is bolting. The JSSW151 is specified for metal to metal applications, the usual case being strut, channel, enclosure flanges, equipment feet and panel mounting. It is a plain flat washer, not a lock washer, so it does nothing to stop a nut backing off under vibration. Add a lock washer or a nylon insert nut where vibration is a factor.
4) What is the Metallics part number and how much shelf space does the jar take?
Order it as Metallics JSSW151. The jar measures 3 x 3 x 2.7 inches, so it drops into a standard bin or van drawer without repacking.
