Metallics W120M – Frequently Asked Questions
1) What bolt size does the Metallics W120M fender washer fit?
The W120M is a 1/2 inch fender washer, so it takes 1/2 inch bolts, lag screws, or threaded rod. The 1-1/2 inch outside diameter gives you three times the bearing surface of the bolt hole, which is the point of a fender washer: spreading load over thin sheet metal, drywall, plywood, or an oversized or slotted hole.
2) Are Metallics W120M washers zinc plated steel, and can they be used outdoors?
Material is zinc plated steel. Zinc plating handles dry interior and protected exterior work, but it is a sacrificial coating, not stainless. For direct weather exposure, wet locations, pool or coastal environments, or anywhere in contact with treated lumber, specify a stainless or hot dip galvanized fender washer instead.
3) How many washers come in a box of Metallics W120M, and how much does the box weigh?
They ship 1000 per box, and the full box weighs 35.33 lbs. Worth knowing before you send someone up a lift or a ladder with it, and worth splitting into a bucket for the job. Carton footprint is 9 x 9 x 6.13 inches.
4) Should I use a fender washer or a standard flat washer for 1/2 inch strut and hanger work?
Use a standard flat washer when you are simply protecting the surface under a nut on a properly sized hole. Go to a fender washer like the W120M when the hole is oversized, slotted, or punched through thin material, or when the substrate is soft. The 1-1/2 inch OD bridges the gap instead of letting the nut pull through. For strut, the proper strut nut and channel washer is still the right part for the channel itself.
5) Will a 1/2 inch fender washer work with 1/2 inch threaded rod on hanging electrical and conduit supports?
Yes. The 1/2 inch inside size of the W120M takes 1/2 inch all-thread, used with a nut on each side where the rod passes through a box, channel, or sheet metal bracket. It is a bare washer only, so nuts, rod, and anchors are ordered separately.
6) Is the Metallics W120M a single item or does it come in multiple sizes?
It is one part number, W120M, in the 1/2 x 1-1/2 size only. If you need a different bolt diameter or a larger OD, that is a different Metallics fender washer part number, not an option on this one.
