Our customer requested these modified steel coupling nuts in plain steel finish and at just 56 pieces. We began with an off-the-shelf coupling nut measuring 5/8-11 for the internal thread, 1" across the flats, and 3.13" in overall length. Material was grade 5 plain steel. Our customers drawing specifications required the internal cavity to be machined to a .65" diameter opening at 1" in depth for both sides, leaving approximately 1.13" of internal 5/8-11 thread in the middle for the mating part to engage. Overall a relatively simple process completed within 1 week of order confirmation.
