Solid pressed wheel nut with bearing plate - has inner cone face and slots in clamping portion formed by pressing and inner thread formed by non-cutting process

摘要

Both the inner tapering surface (12) and the slots (8) of the sleeve (3) are formed by solid-shaping. The entire thread (11) can be formed without cutting, e.g. by rolling, whirling etc., typically in a numerically-controlled lathe. There can be a peripheral groove at the join between the parallel and tapering threads. Where the pressure plate is added to the nut, this can be a solid pressing and secured to the nut so as to turn in relation to it. ADVANTAGE - Will not work loose even after being used many times.
