Add strong, clean threaded mounts to tubing or plate
These 5/16"-24 TPI threaded weld washers make it easy to add a durable threaded mounting point where tapping isn’t practical—perfect for thin-wall tubing or flat plate. Just drill a 3/4" hole, drop one in, and weld it in place. They fit 1.25" or larger tubing as well as flat surfaces, making them ideal for mounting tabs, panels, or accessories without using questionable hardware fixes.
