Metallics W1135M – Frequently Asked Questions
1) What size bolt does the Metallics W1135M fender washer fit, and how wide is the washer itself?
The W1135M is a 1/4 inch fender washer with a 1 inch outside diameter. The 1/4 inch inner hole takes a 1/4-20 bolt or screw, and the 1 inch OD spreads the load over roughly four times the bearing area of a standard 1/4 inch flat washer. That extra face is what you want over an oversized hole, sheet metal, drywall, or soft material that a standard washer would pull through.
2) Are Metallics W1135M fender washers plated for corrosion resistance, and can they be used outdoors?
They are steel with a zinc plating. Zinc gives ordinary indoor and protected-exterior corrosion protection, so they hold up in mechanical rooms, panel work, and covered exterior runs. For continuous wet, coastal, or chemical exposure, specify stainless rather than zinc-plated steel.
3) How many washers come in a box of Metallics W1135M, and how much does the box weigh?
One box holds 5,000 washers and weighs 54.19 lbs. Box measurements are 9 x 9 x 6.13 inches. That is a bulk MRO or jobsite quantity, not a contractor pack, so plan shelf space and factor the weight if it is going on a truck or a parts cart.
4) Should I use a fender washer or a standard flat washer for mounting electrical boxes and strut hardware?
Use a fender washer like the W1135M when the hole is oversized, the material is thin or soft, or the load needs spreading, mounting a box to drywall or sheet metal, bridging a slotted or burned-out hole, backing up a through-bolt in wood. A standard 1/4 inch flat washer is the right call on a drilled hole in steel or when you need the washer to sit inside a narrow strut channel or under a nut in a tight pocket, since the 1 inch OD will overhang. Fender washers are thinner relative to their diameter, so they are a load-spreader, not a structural washer for high-torque bolted connections.
5) Is the Metallics W1135M washer an ANSI dimensional standard part?
The W1135M is listed to an ANSI dimensional standard, so the 1/4 inch ID and 1 inch OD follow published inch-series washer dimensions rather than a proprietary pattern. For a facility or institutional spec calling out inch-series washers, it interchanges with other ANSI-dimensioned 1/4 x 1 fender washers.
6) What is the exact part number to order 1/4 x 1 zinc fender washers from Metallics?
Order Metallics part number W1135M. That number covers the 1/4 x 1 inch zinc-plated steel fender washer supplied 5,000 to the box. There is one configuration under that number, so there is no finish or length option to specify on the purchase order.
