Abstract

789,039. Bolts. VERTRIEB-UND VERKAUF-AKT.-GES. Dec. 23, 1955 [Dec. 24, 1954], No. 36969/55. Class 89(1) [Also in Group XXIII] A screw-bolt for use with a socket - wrench, (Group XXIII), has a profiled-disc 20 separated from the hexagonal-head 18 by an annulargroove 19. The disc 20 has six lateral projections 23 which coincide with the corners of the hexagon 18 and prevent removal of the bolt-head from the socket until the latter has exerted the required amount of tightening-torque to the bolt.
