- Well controlled forging and latheing processes followed by careful fine-tuning of heat treatment yields sockets containing desired Martensite structure with HRC in the range of 42 ~ 48.
- All of Crossman’s sockets and wrenches pass torsion test with tolerable limits at least 20% higher than those given by ANSI (American National Standard institute).
- Final finishing:
- (a) Mirror finishing: possessing the smoothest surface with electroplated
- (a) chromium over nickel layers.
- (b) Matt finishing:
- (c) zSatin finishing: possessing the largest resistance to scratching
- (d) Zinc phosphate finishing: possessing acid-resistance black zinc phosphate layer
