Metallics JMSW03 – Frequently Asked Questions
1) What size screw do Metallics JMSW03 flat washers fit?
The JMSW03 is an M3 flat washer, so it is sized for M3 metric machine screws and bolts. If your fasteners are imperial, M3 is close to a #4 screw but not an exact substitute, so stay with metric hardware for a proper bearing surface under the head or nut.
2) Are the Metallics JMSW03 M3 washers zinc plated for corrosion resistance?
They are zinc plated steel. That plating handles dry indoor work, panel builds, enclosures and fixture assembly fine. For damp, exterior or washdown locations, zinc plated steel will eventually corrode, so stainless is the better call there.
3) How many M3 washers come in a jar of Metallics JMSW03?
Each jar holds 100 M3 flat washers. The jar is the pack format, which keeps them contained on a service cart or in a van drawer instead of loose in a bin, and 100 pieces covers a typical panel or fixture job without a bulk box.
4) Can I use M3 flat washers like the JMSW03 in electrical panel and fixture assembly?
Yes, that is the usual use. The JMSW03 is stocked as electrical fastener hardware, and an M3 flat washer spreads the load under a small screw head or nut so you are not digging into sheet metal, a device plate or a fixture housing. It is a flat washer, not a lock washer, so it does nothing to resist loosening from vibration, pair it with a lock washer or a nylon insert nut where that matters.
5) What is the exact part number to order these M3 zinc flat washers?
Order Metallics part number JMSW03. That number covers the M3 flat zinc plated steel washer in the 100 piece jar, and it is the only configuration offered under it, so there is no finish or pack option to specify.
6) What does a jar of 100 M3 flat washers weigh and how much space does it take up?
The jar comes in at 0.08 lbs with dimensions of 3 x 3 x 2.15 inches. Light and small enough to drop into a tool bag or stock on a shelf alongside other small fastener jars.
7) Where are Metallics JMSW03 washers made?
Manufactured in China. Worth knowing up front if you are buying against a domestic-origin or Buy American requirement on a government or institutional job, since this part would not satisfy that clause.
