Abstract
642,917. Screws. OHIO NUT & BOLT CO. July 24, 1947, No. 19922. Convention date, March 23, 1946. '[Class 89(i)] [Also in Group XXII] Screws, particularly adjusting or levelling screws, have cold forged heads 22, Fig. 7, of greater diameter than standard, a neck portion 10, and a shank of reduced diameters 8, 21. The diameter of the part 21 is such that after rolling a thread, the crest diameter is equal to that of the part 8. Instead of the domed head 22, adjusting screws may have flat heads shaped as shown in Fig. 10 to facilitate hand grip.
