We supplied these custom ultra fine threaded studs to our customer in the civil engineering and construction field. They measure 5/16-32 X 1-1/4 and are manufactured domestically with a lead time of 1-2 weeks. 100 pieces were produced with each side chamfered by hand. Unlike the typical threaded studs used in construction, these ultra fine thread parts were very temperamental and required extra care during the production process and handling. Even the smallest error in the chamfering process or a small dent in the thread from handling/shipping could ruin the thread run and cause jamming on the mating parts.
