Project Description
These custom carriage bolts were produced to our customer’s drawing to class 10.9 characteristics with black oxide finish. Approximately 27MM of M10-1.5MM 6G thread was rolled underneath the square shoulder and a 3MM hole was drilled through one side of the shoulder. The square shoulder was produced to 10MM across the flats. Under the head a R45 radius was maintained to match the mating washer.
