Abstract

1417537 Screw sockets; anchored nuts A FISCHER 28 May 1974 [29 May 1973] 23513/74 Heading F2H A fastener 1 comprises a bolt 3 having a screw-threaded shank portion 2, an expansible member 5 having first and second collars 7, 4 joined together by legs 6, and a cap 9 firmly embracing the outer cylindrical surface of the first collar 7, the cap 9 diameter being slightly larger than that of a bore 8 in a structural element 13 in which the fastener is to be secured so that the first collar 7 may be frictionally retained in one end of the bore 8 while the bolt 3 is inserted from the other end of the bore to pass through the first collar 7 and into screwthreaded engagement with the second collar 4, rotation of the bolt drawing the second collar 4 towards the first and collapsing the legs 6 radially outwardly. The legs have cut-outs 6a to assist this collapse. The bolt 3 has a first shank portion 3b of approximately the same outer diameter as the collars 4, 7, and a reduced diameter portion 3a on which the screw-thread 2 is formed. The cap 9 is of plastics.
