Abstract
1,015,300. Screw-sockets; locking nuts. HELI-COIL CORPORATION. Oct. 14, 1964, No. 41823/64. Heading F2H. A screw-thread insert of coiled wire having an angular, e.g. diamond, cross section, has at least a section of a turn twisted about the axis a-a, Fig. 1, of the wire 10. Alternate sections 15, 16 of wire may be twisted in opposite directions, e.g. so that crosssections of the wire are set at 40 to 50 degrees to the untwisted cross-sections, some in one direction as at 17, Fig. 7, and others in the other direction as at 18. The twisted sections 15, 16 may be separated by untwisted sections or there may be merely sections twisted in one direction only and separated similarly. When the wire is coiled for insertion in a tapped bore, some or all of the turns may have twisted sections. When a bolt is screwed in, the twisted sections 17, 18 are moved in the direction of the untwisted positions, as indicated by the arrows in Fig. 7, to lock the insert 11 in the thread groove 13 of the tapped bore 12 and the bolt in the insert.
