Abstract

1,146,241. Locking fastener. LAMSON & SESSIONS CO. 11 Jan., 1967 [16 Feb., 1966], No. 1447/67. Heading F2H. A fastener, e.g. a lock-nut, has a locking thread convolution which differs from the basic form for mating with a co-operating standard thread 24 so as to interfere with the mating thread to provide a locking action, the thread angle being the same as for the basic form but the width of the metal convolution between the flanks 30, 32 being greater than the maximum width for a standard thread of the same basic form so as to provide uniform interference with a standard mating thread along the flanks 30, 32 of the locking thread convolution. A recess 35 is provided between adjacent threads which is axially larger than the space defined by the triangle between adjacent threads and which extends radially from the position of the crest 40, 36 of the standard mating thread. The recess 35 is designed to accommodate metal swaged due to the thread interference to prevent seizure of the threads. The locking convolutions are formed in a resilient collar portion 22 of a nut such that the collar expands outwardly due to the thread interference but exerts a force inwards on the threaded stem due to its resiliency to effect a further locking action.
