Metallics JMSW12SS316 – Frequently Asked Questions
1) Are the Metallics M12 flat washers 316 stainless or 18-8?
They are stainless steel, and the part number JMSW12SS316 carries the 316 designation. 316 is the grade electricians and marine or coastal installers specify when 18-8 would pit, such as wash-down areas, exterior rooftop equipment, or chemical exposure.
2) How many washers come in a jar of Metallics JMSW12SS316?
The JMSW12SS316 ships as a jar of 100 M12 flat washers. The jar is the packaging unit, so one order line gets you 100 pieces for a panel build or a run of strut and anchor work. Jar weight is listed at 1.2 lbs.
3) Can I mix 316 stainless washers with galvanized or plated steel bolts?
You can, but watch the dissimilar metal contact. Stainless against zinc-plated or hot-dip galvanized steel in a damp or coastal setting will drive galvanic corrosion of the zinc coating. For exterior or wash-down work where you are buying 316 washers for the corrosion resistance, match the bolts and nuts in stainless too.
4) What is a flat washer used for in an electrical install versus a lock washer?
A flat washer like the M12 Metallics spreads the clamp load of the bolt head or nut over a wider area, which keeps the fastener from pulling through sheet metal or crushing a soft surface. It does not resist loosening from vibration. If the connection sees vibration, pair it with a split lock washer or a locking nut; the flat washer still goes against the work surface.
5) Is the Metallics M12 washer made to a recognized dimensional standard?
The JMSW12SS316 is built to ANSI dimensional standards. Country of origin is listed as multiple, so sourcing can vary between production runs while the dimensional spec holds.
6) How much shelf or van space does a jar of Metallics M12 stainless washers take?
The jar measures 3 x 3 x 2.15 inches and weighs 1.2 lbs, so it drops into a service van bin or a parts drawer without repackaging. Useful if you are stocking several metric sizes side by side on a truck.
