Abstract
1290562 Making screws AMP Inc 9 July 1971 [24 July 1970] 35910/70 Heading B3A [Also in Division F2] A stick of screws is formed from extruded stock of cruciform cross-section. The ribs 1 are cut away to define tapering leading edges 2, portions 5 of reduced height, and heads 6. The rib portions 5 are serrated by teeth 7 forming an interrupted screw-thread. Slots 8 are provided to weaken the connection between adjacent screws and to serve as screw-driver slots. Tongues 9 may be provided as locking members.
