Metallics JMSW12SS – Frequently Asked Questions
1) Are these M12 washers stainless steel or plated steel?
Stainless steel, not zinc-plated carbon steel. That matters if the hardware is going outdoors, in a damp vault, on rooftop equipment, or anywhere a plated washer would bleed rust onto the finish. Pair them with stainless bolts and nuts to avoid mixing dissimilar metals at the joint.
2) How many washers come in the Metallics JMSW12SS jar?
The JMSW12SS is a jar of 100 M12 flat washers. They ship in a jar rather than a loose bag, so you can keep the count on a cart or in a van bin without spills. Total packed weight is 1.31 lbs.
3) What is the exact part number to order M12 stainless flat washers from Metallics?
Order Metallics part number JMSW12SS. The J prefix marks the jar pack; it is the M12 flat stainless washer in a 100 count jar. Country of origin is China.
4) Can I use these M12 stainless washers outdoors or in a wet location?
Stainless steel construction is what makes them suitable for damp and exterior mounting, where a plated washer would eventually rust and streak. Keep the whole joint stainless, since a stainless washer under a plated bolt still leaves the bolt as the thing that corrodes first.
5) What are M12 stainless flat washers used for on an electrical job?
Flat washers spread the clamp load of a nut or bolt head so it does not pull through or dig into the material underneath. On electrical work that is typically strut and channel mounting, hanging threaded rod for cable tray or conduit racks, anchoring enclosures and panels, and bonding or grounding hardware where a stainless washer is wanted for corrosion resistance. The JMSW12SS is a Metallics electrical fastener item, so it is stocked for exactly that kind of installation.
6) How much shelf or bin space does the jar of 100 M12 washers take up?
The jar measures 3 x 3 x 2.7 inches and weighs 1.31 lbs, so it drops into a standard small-parts bin or a van drawer alongside other jarred fastener counts. Useful if you are standardizing a fastener wall and want a consistent footprint across sizes.
