Metallics JSW76D – Frequently Asked Questions
1) What bolt size do the Metallics JSW76D flat washers fit?
The JSW76D is a 1/2 inch flat washer, so it is sized for 1/2 inch bolts, machine screws, threaded rod, and anchors. Pair it with 1/2-13 rod or hardware and it seats flat under the nut.
2) Are these 1/2 inch flat washers plated for corrosion resistance?
Yes. The JSW76D washers are zinc plated steel. That plating handles normal indoor and protected outdoor electrical work (strut, hangers, panel mounting), but zinc is not the choice for direct weather exposure, wash-down, or coastal sites. For those, go stainless.
3) How many 1/2 inch flat washers come in a jar of Metallics JSW76D?
Each jar holds 100 washers. Metallics packs them in a jar rather than a loose bag, which is what makes them practical to keep on a service cart or in a job box without spilling.
4) Will 1/2 inch flat washers work with 1/2 inch threaded rod and strut hangers?
That is the normal use. A 1/2 inch flat washer spreads the nut load across the strut or channel surface so the nut does not pull through or dig in, and it goes under the nut on 1/2 inch rod drops for conduit and cable tray supports.
5) Are Metallics JSW76D washers made in the USA?
Country of origin is the United States, which matters on public work and institutional jobs carrying domestic sourcing requirements for fasteners.
6) Are these washers built to a standard dimensional spec?
The JSW76D is an ANSI dimensioned 1/2 inch flat washer, so the outside diameter and thickness follow the standard rather than a proprietary pattern. That means it interchanges with other ANSI 1/2 inch flat washers already on the job.
7) Do I need a lock washer too, or is a flat washer enough?
A flat washer like the JSW76D distributes load and protects the mating surface; it does not resist loosening. On assemblies that see vibration, add a split lock washer or a locknut and keep the flat washer against the material.
8) How much does a jar of 100 Metallics 1/2 inch flat washers weigh and how big is the jar?
The packed jar weighs 1.77 lbs and measures 3 x 2.7 x 3 inches, so it drops into a van bin or tool drawer easily. Useful if you are stocking several sizes side by side on a shelf.
