Since changing my design philosophy, I no longer need single thread worms. These worms were custom designed for me, made in brass, 32P .500" dia. o/a length 13/16", thread block 9/16" drilled for .125 shaft also drilled for two set screws 90 degrees apart. PD .438". I have 100 pcs. and another 100 at the vendors shop. The pricing will be based upon the quantity ordered. I would rather sell the whole lot, but realize most would not have a need for such a large number. Individually, they are $15.00 each plus shipping.
