Abstract
754,170. Screw-sockets. BOOTS, N. J. June 18,1954, No. 17976/54. Class 89 (1). A screw-socket comprises an internallythreaded tubular body 9, Fig. 2, with a flanged head 8 and longitudinal slots 10, the inner end 11 of the body being bevelled and there being above this end a band of diamond knurling 13. On insertion into a hole 12, of slightly less diameter than the body, the body collapses slightly, but is restored to substantially original size 'when a screw 14 is driven home, thus embedding the knurlings in the wall of the hole. The screw may have a bevelled lead 15. The head 8 may be closed or the threads may extend completely through the insert, which frictionally engages the screw. In another arrangement, the insert 116, Fig. 7, is headless for insertion into a blind hole in a part 112.
