Nothing in this document, however, supersedes applicable laws and regulations unless a specific exemption has been obtained.
After removal of oxide as in 3.3.3, the head-to-shank fllt radius of parts having the radius complete throughout the circumference of the part shall be cold rolled. Cold rolling shall be sufficient to remove all visual evidence of grinding or tool marks. Distortion due to cold rolling shall conform to Figure 1, unless otherwise specified on the part drawing. It shall not raise metal more than 0.002 inch above the contour at“A” or depress metal more than 0.002 inch below the contour at“B” as shown in Figure 1; distorted areas shall not extend beyond “C” as shown in Figure 1. In configurations having an undercut connected with the fllet radius, the cold rolling will be required only for 90° of fllet arc, starting at the point of tangency of the fllet radius and the bearing surface of the head. For shouldered bolts having an unthreaded shank diameter larger than the thread major diameter and having an undercut connected with a fllet between the threaded shank and the shoulder of the unthreaded shank, the cold rolling will be required only for 90° of fllet arc, starting at the point of tangency of the fllt radius and the shouldered surface of the unthreaded shank. The shank diameter on full shank close tolerance bolts shall not exceed the nominal thread diameter after cold rolling the head-to-shank fllet radius.SAE AS 4877F pdf free download.
