Edward W. Daniel Machinery Eyebolts are manufactured to ASME B18.15 and tested to ASTM A489 specifications. The minimum threaded shank length of Eyebolts must be one thread diameter to attain the rated capacity. No greater load should be applied to an Eyebolt than the Rated Capacity listed. Angular lifts significantly reduce Shoulder Eyebolt Rated Capacities. Shoulder Eyebolts should not be used for angular lifts greater than 45º.
