Abstract

1,269,611. Lock-nuts. PATEREX Ltd. 5 Jan., 1971 [5 Jan., 1970], No. 500/70. Heading F2H. A lock-nut has two coaxial internally threaded parts 1, 2 joined by a frangible wall portion 4 of reduced thickness defined between internal and external annular grooves 3, 5, the internal groove 3 housing a sealing ring 8 of resilient or compressible material (e.g. an O-ring of silicone rubber) which is compressed to lock against a coacting bolt thread when the portion 4 shears under a predetermined torsional force during application of the nut. The nut preferably has a head 9 provided with wrenching faces and connected to the part 1 by a thin walled portion 10 of greater shear strength than the portion 4 so, that, after locking of the nut, the head may be broken away and discarded. The part 2 and head 9 may be provided with counterbores 7 and 12 respectively; and the nut is preferably made of an aluminium alloy and has an anodized surface.
