Metallics JMSWS012 – Frequently Asked Questions
1) What size bolt does the Metallics JMSWS012 flat washer fit?
It's an M12 flat washer, so it's sized for M12 metric threaded rod, bolts, or screws. If your rod is 1/2 inch imperial rather than M12, use an imperial 1/2 inch washer instead; the two are close but not the same bore.
2) Is the JMSWS012 a small OD or regular OD washer?
Small outside diameter. It's the narrower-footprint M12 flat washer, which matters when you're washering into a tight channel, strut, or a bracket slot where a standard-OD washer overhangs. If you need more bearing surface to spread load on sheet metal or soft material, go with a regular or fender-style M12 washer instead.
3) Are these M12 washers zinc plated for corrosion resistance?
Steel with a zinc plating, which is the standard finish for interior electrical and mechanical work. It handles normal indoor humidity, but for exterior, wet, or corrosive locations spec stainless or hot-dip galvanized hardware instead.
4) How many washers come in a jar of Metallics JMSWS012?
100 pieces per jar. The jar pack is the handy size for a service van or a shop bin, since the lid keeps them contained instead of loose in a drawer.
5) Can I use these M12 flat washers with threaded rod hanging conduit or strut?
Yes, that's the common use. An M12 flat washer sits between the nut and the strut, channel, or bracket so the nut doesn't pull through the slot and the load spreads over a larger area. Keep in mind it's a small-OD washer, so on wide strut slots check that the washer still bridges the opening.
6) What is the Metallics part number I should order for M12 small-OD zinc flat washers?
Metallics JMSWS012. That's the manufacturer part number for the M12 small outside diameter zinc-plated steel flat washer in the 100-piece jar.
7) Will a flat washer alone keep the nut from backing off?
No. A flat washer only spreads load and protects the surface, it does nothing against vibration. If the connection sees movement, add an M12 split lock washer or a nylon-insert lock nut on top of the flat washer.
