摘要： A self-reacting center wheel nut assembly includes a reaction ring (120) formed between a center wheel nut (110) and a lock collar assembly (130). The self-reacting center wheel nut assembly may also include a washer (140) and O-rings. The self-reacting center wheel nut assembly improves and simplifies wheel bolt tightening; uses the lock collar assembly as a reaction point by transferring opposing torque generated during installation and removal through the reaction ring, which is reacted on by a dual sleeved drive assembly; may be used with HYTORC electric battery powered torque multiplier gun/tools to deliver quick, accurate and precise torque; eliminates the need for external reaction points such as the rim or ground, thereby eliminating side loads and damage to the wheel; is fully sealed and lubricated; eliminates vehicle movement and the need to lock the brakes; reduces operator fatigue, chances of injury and saves operator time and energy.

摘要： According to a first aspect of the invention we provide an apparatus (1) for use with a threaded fastener including: —an inner sleeve member (100) having an internal surface threadedly engagable with the fastener and a tapered external surface; and an outer sleeve member (200) having an inversely tapered internal surface rotatably engagable with the tapered external surface of the inner sleeve member. Advantageously, the invention allows for an increased load bearing surface area between the inner sleeve member (100), which is clamped, and the outer sleeve members (200) without increasing the overall diameter of the apparatus (1) 6; a three dimensional load bearing surface area rather than a conventional two dimensional plane; more efficiently and evenly distributed load stress distribution over the load bearing surface area; higher torsion strength; and apparatus with lower mass, dimensions and volume.
