Metallics JW110 – Frequently Asked Questions
1) What screw size does the Metallics JW110 fender washer fit?
The JW110 is a #10 fender washer with a 3/4 inch outside diameter, so it takes a #10 machine screw, sheet metal screw, or bolt through the bore. If you are running 1/4-20 hardware, this is the wrong size - you need a 1/4 inch fender washer instead.
2) Why use a fender washer instead of a standard flat washer on sheet metal or drywall?
A fender washer has a much larger outside diameter relative to its bore, which spreads the clamping load over more surface. That is what keeps a #10 screw from pulling through thin sheet metal, a drywall or plaster ceiling, fiberglass, or an oversized hole. A standard #10 flat washer is roughly the head diameter and will dish straight through soft material.
3) Are the Metallics JW110 washers plated for corrosion resistance?
They are steel with a zinc chromate finish, which handles normal indoor and light damp duty - panel mounting, strut and box work, ceiling hangers. For sustained wet, coastal, or exterior exposure, step up to stainless; zinc plating will eventually bloom white and rust.
4) Can I use these fender washers on plumbing and HVAC work, or are they electrical only?
Metallics lists the JW110 for electrical, plumbing, heating and air conditioning work. It is a general purpose zinc plated steel fender washer, so it is equally at home backing a #10 screw on a junction box, a strap on a duct collar, or a hanger bracket on a pipe run.
5) How many washers come in a jar of Metallics JW110?
Each jar holds 100 of the #10 x 3/4 fender washers, packaged in a jar rather than a bag, which keeps them from scattering in a van or on a cart. Total jar weight is 0.7 lbs.
