Abstract

1296887 Taking threaded fasteners - SIMMONDS SA 25 June 1970 [30 June 1969] 30870/70 Heading B3A [Also in Division F2] An internally or externally threaded fastener devise is formed by screw-threading a cylindrical annulus, machining an annular groove 8 in the unthreaded cylindrical wall substantially medially of the ends of the annulus and then milling notches 4 on an axial end face to the depth of the groove to leave projections 5. The projections are bent inwardly or outwardly so that they can resiliently engage the member on to which the devise is screwed.
