Abstract

1392360 Screw driver and screw J W BARLOW 19 July 1972 30167/72 Heading B3N [Also in Division F2] A screw driver comprises a handle 12 and a blade 13 having a bit 14 and keys 16, 17. A screw has a cross-slot 24 with keyways 26, 27 to accept the keys 16, 17. The base of the slot and the keyways slopes downwardly from an apex 28. Thus the slot and each keyway slopes along its length and across its width.
