Metallics JSW69 – Frequently Asked Questions
1) What size screw do Metallics JSW69 flat washers fit?
The JSW69 is a #5 flat washer, so it pairs with #5 machine screws and sheet metal screws. If you are working with #6 or #8 hardware, which is far more common in device and box mounting, the #5 washer will be undersized on the shank clearance side and you want the matching #6 or #8 flat washer instead.
2) Are the Metallics JSW69 washers plated for corrosion resistance?
They are zinc plated steel. That is a standard indoor and dry-location finish, fine for panel work, device boxes and general interior fastening. For sustained wet, exterior or corrosive exposure, step up to stainless flat washers rather than zinc plated steel.
3) How many washers come in a jar of Metallics JSW69?
One hundred #5 flat washers per jar, packed in a screw-top jar rather than a bag, so partial counts stay contained on a cart or in a van bin. The filled jar weighs 0.14 lbs.
4) Is the Metallics JSW69 washer made to a dimensional standard?
Yes, it is an ANSI dimensional washer, so the inside and outside diameters follow the published #5 flat washer dimensions rather than a proprietary pattern. That matters if you are mixing stock from more than one supplier on the same job.
5) What part number do I order for Metallics #5 zinc flat washers?
Order Metallics JSW69. That number covers the #5 flat, zinc plated steel washer in the 100-piece jar, and it is the only configuration under that part number, so there is no size or finish suffix to specify.
6) Will a jar of JSW69 washers fit in a standard parts bin or van drawer?
The jar measures 3 x 3 x 2.15 inches, so it drops into most small-parts drawers and bin dividers without decanting. Useful for MRO shops standardizing loose fastener stock into labeled jars.
7) What are flat washers actually for on an electrical install?
A flat washer spreads the clamping load of the screw head over a wider area and protects the surface underneath it. On electrical work that means keeping a screw head from pulling through thin sheet metal, a plastic device body or an oversized or slotted hole in a box, cover or strut fitting. If you need the fastener to resist loosening from vibration, a flat washer alone will not do it, use a lock washer or add one under the flat.
8) Where is the Metallics JSW69 washer manufactured?
Country of origin is China. Worth confirming against your spec if you are buying for a government or federally funded project with domestic sourcing requirements.
