Abstract

583,250. Helical screw inserts. AIRCRAFT SCREW PRODUCTS CO., Inc. Sept. 4, 1944, No. 16801. Convention date, Dec. 16, 1943. [Class 89 (i)] [Also in Group XXII] A helix of round, square &c. wire to serve as an inserted screw thread, as described in Specification 497,309, has the leading end notched at 3 to form a radial or undercut edge 4 to engage an inserting tool. The end 5 of the helix may be bevelled to produce a sharp point 7 that tends to dig into the bolt and prevent unscrewing. To facilitate the formation of the notch after coiling the end turn may be to a less radius or the end may be,bent inwards resiliently or otherwise and restored after notching. The notch extends for about half the depth of the wire.
