Metallics JW117 – Frequently Asked Questions

1) Will a 3/8 fender washer fit a 3/8 inch bolt or threaded rod?
Yes. The Metallics JW117 fender washer has a 3/8 inch inside diameter, so it slips over 3/8 inch bolts, screws and 3/8-16 threaded rod used for conduit and duct hangers. The 1-1/2 inch outside diameter gives you four times the bearing width of the hole itself, which is the point of a fender washer.
2) What is a fender washer good for that a standard flat washer isn't?
Pull-through. A standard 3/8 flat washer has a small outside diameter and will sink into sheet metal, drywall, or thin panel when you torque it down. The Metallics 3/8 x 1-1/2 fender washer spreads that same load across a 1-1/2 inch face, so it holds on duct, enclosure sheet metal, and soft substrates. If you are bolting into structural steel or a tapped boss where the surface can take the load, a standard flat washer is the right part and the fender is overkill.
3) Is the zinc chromate finish on these washers okay for outdoor or damp locations?
The JW117 is steel with a zinc chromate finish, which is a corrosion-resistant plating meant for general electrical, plumbing and HVAC work, including damp interior spaces and mechanical rooms. It is a plated coating, not stainless, so for continuous wet exposure, coastal air, or wastewater environments, specify stainless.
4) Can I use these washers in a grounding or bonding connection?
The washer is plated steel, and the zinc chromate finish is conductive, so it will pass current in a bonding path. It is a load-spreading washer, not a listed grounding washer or paint-piercing bonding washer, so where the NEC calls for a bonding bushing or a paint-penetrating washer on an enclosure, use the part specified for that. For clamping a bond lug flat against a panel, it does the job.
5) How many fender washers come in a jar, and how much does it weigh for shipping?
Each jar holds 100 pieces of the 3/8 x 1-1/2 fender washer. The packed jar weighs 2.82 lbs and measures 3 x 3 x 4.57 inches, so it drops into a van bin or a gang box without taking a shelf.
6) Are these washers made to a recognized dimensional standard?
Yes, the Metallics fender washer is manufactured to ANSI dimensional standards, which is what keeps the 3/8 bore and 1-1/2 inch outside diameter consistent jar to jar when you are standardizing a stock room across multiple buildings. Country of origin is listed as multiple.
