1,125,071. Nuts. UNITED-CARR Inc. 3 March, 1967 [3 March, 1966], No. 10220/67. Heading F2H. [Also in Division B3] A nut adapted to engage a bore 9 in a support 8 comprises an internally screw-threaded barrel 2 having a laterally extending flange 3 and prongs 4. When the nut is driven into the bore the prongs 4 bite into the wall of the bore to lock the nut in the support. A punch shapes the portion of the barrel between the flange and the prongs to a hexagonal form and another punch shears material from the barrel to form the prongs, leaving holes 5.
