Metallics JMSW8SS – Frequently Asked Questions
1) What size bolt does the Metallics JMSW8SS flat washer fit?
The JMSW8SS is an M8 flat washer, so it pairs with metric 8mm bolts, machine screws, and threaded rod. It is not a fit for imperial 5/16 inch or 3/8 inch hardware, so if the fastener on your job is inch-series, you want a SAE or USS washer instead of this one.
2) Are the Metallics M8 washers stainless steel, and will they hold up outdoors or in a damp electrical room?
Stainless steel is the material, which is why electricians reach for these over plain or zinc-plated washers on exterior strut runs, rooftop equipment, pump rooms, and wash-down areas. Stainless resists rust where plated steel starts bleeding at the washer face.
3) How many M8 washers come in the Metallics JMSW8SS jar?
One hundred M8 flat stainless washers, supplied in a jar rather than a loose bag. The jar is the handier format for a van or a shop bench since it reseals and the count stays intact. Total weight of the packaged jar is 0.4 lbs.
4) Can I mix these stainless M8 washers with galvanized strut and hardware?
Mechanically yes, but be deliberate about it. Stainless in direct contact with galvanized steel in a wet location sets up galvanic action and the zinc coating sacrifices first. For dry interior strut runs it is a non-issue; for exterior or damp work, keep the whole stack stainless.
5) What is the Metallics JMSW8SS flat washer actually used for on an electrical install?
It spreads the load under an M8 nut or bolt head so the fastener does not pull through or dig into the material it is clamping. Typical use is anchoring strut, hanging conduit supports, mounting enclosures and panels, and anywhere a metric 8mm bolt lands on sheet metal or a slotted channel. A flat washer does not resist loosening on its own, so add a lock washer or a nylon insert nut where vibration is a factor.
6) What part number do I order for Metallics M8 stainless flat washers?
Order Metallics JMSW8SS. That single part number covers the M8 flat stainless washer in the 100-count jar, so there are no size or finish options to pick through at order time.
7) What are the jar dimensions for the Metallics JMSW8SS washers, for shelf or bin storage?
The packaged jar measures 3 x 3 x 2.15 inches, so it drops into a standard small parts bin or a van drawer without repackaging. Useful if you are standardizing a fastener wall and need the footprint before you order.
8) Is the Metallics JMSW8SS washer dimensioned to an ANSI standard?
The JMSW8SS is built to ANSI dimensional standards in the M8 size, which is what lets a procurement buyer drop it into a spec that calls for standardized flat washers rather than an unspecified commercial part.
