Abstract

542,524. Wood &c. screws. HOLO-KROME SCREW CORPORATION. May 9, 1940, No. 8393. Convention date, May 26, 1939. [Class 89 (ii)] [Also in Group XXIII] Screws with sockets for receiving a driver have surfaces adjacent the bottom of the socket for engaging the driver with a wedging action. The sockets have a number of radial flutes 3, Fig. 1, the bottoms 9 and intersections 11 of which are convex. The driver, Fig. 9, is of a form corresponding to that of the socket but does not button therein so that axial pressure causes a wedging action.
