Metallics JSWBR68 – Frequently Asked Questions
1) What size screw does the Metallics JSWBR68 flat washer fit?
The JSWBR68 is a #4 flat washer, so it pairs with #4 machine screws or #4 wood screws. If you're fastening #6 or #8 hardware, this one's bore is too small and you'll need the matching washer for that screw size.
2) Are these Metallics #4 washers solid brass or brass plated?
Brass is the stated material for the JSWBR68 washer. That matters on two counts for electrical work: brass is non-magnetic and it won't rust the way a plain steel washer does, which is why it gets used on brass terminal hardware, ground screws, and anywhere you don't want galvanic mismatch against brass or bronze fittings.
3) How many washers come in a jar of Metallics JSWBR68?
100 washers per jar, and the jar is the pack format, not a loose bag. The screw-top jar is what MRO and service-van buyers want it for, since a #4 washer is small enough to disappear out of a torn poly bag.
4) Will a brass #4 flat washer hold up in a damp or outdoor enclosure?
Brass is the material here, so it won't corrode the way bare steel does in humid, coastal, or washdown locations. That makes the JSWBR68 a reasonable pick for exterior fixtures, pool and fountain equipment covers, and damp mechanical rooms where a plated steel washer would bloom rust around the screw head.
5) Why use a flat washer under a #4 screw instead of just driving the screw?
A flat washer spreads the clamp load of the screw head over a wider area and gives the head a clean bearing surface. On a #4 screw the head is tiny, so without a washer it can pull through sheet metal, soft plastic device plates, or thin gasket material. The JSWBR68 brass washer also keeps a brass screw head from chewing into the finish on a brass or bronze plate.
6) Is the Metallics JSWBR68 washer made to an ANSI dimensional standard?
ANSI is the dimensional standard cited for the JSWBR68, so the #4 washer's inside and outside diameter follow standard ANSI flat washer proportions rather than a proprietary pattern. Practically, that means it interchanges with other ANSI-dimensioned #4 flat washers already in your hardware stock.
7) What is the shipping weight and jar size on the Metallics JSWBR68?
The jar of 100 is listed at 0.09 lbs and measures 3 x 2.15 x 3 inches. Small enough to live in a bin drawer or a van parts tray rather than on a shelf.
