摘要:
A fastener driving tool (300, 900, 900') includes a shaft (902, 902', 902'', 1016, 1216, 1312, 1512, 1612) with a working region (304, 904, 908, 904', 908', 904'', 908'', 1020, 1220, 1316) disposed at a first end of the shaft (902, 902', 902'', 1016, 1216, 1312, 1512, 1612) and configured to drive a fastener (54), a shank portion (302, 476, 558, 840) disposed proximate a second end of the shaft (902, 902', 902'', 1016, 1216, 1312, 1512, 1612) and configured to couple the shaft (902, 902', 902'', 1016, 1216, 1312, 1512, 1612) to a power tool (2), and a reduced diameter torsion zone (306, 912, 912', 912'', 914, 914', 914'', 934'', 572, 561, 1010, 1011, 1012, 1014) disposed between the shank portion (302, 476, 558, 840) and the working region (304, 904, 908, 904', 908', 904'', 908'', 1020, 1220, 1316), the torsion zone (306, 912, 912', 912'', 914, 914', 914'', 934'', 572, 561, 1010, 1011, 1012, 1014) extending from a first shoulder (916', 916'', 918') closer to the working region (304, 904, 908, 904', 908', 904'', 908'', 1020, 1220, 1316) to a second shoulder (920', 920'', 922') closer to the shank portion (302, 476, 558, 840). A length (L) and a radius (c) of the torsion zone have been optimized so that approximately half of breakages occur in the working region (304, 904, 908, 904', 908', 904'', 908'', 1020, 1220, 1316) and approximately half of breakages occur in the torsion zone (306, 912, 912', 912'', 914, 914', 914'', 934'', 572, 561, 1010, 1011, 1012, 1014).
