A simple, reliable, easily fitted and removed bolt securing system for a through-bolt (1) with a hexagonal (multiple-flat) nut (2) and with, at the end of its threaded shank, an additional smaller thread turning in the opposite direction, whereby the securing nut (3), which has a thread opposite to that of the retaining nut (2), and an annular securing plate (4) secure the retaining nut (2) and securing nut (3) together, preventing rotation, so that finally also the through-bolt or retaining bolt (1) is absolutely prevented from becoming accidentally loose. Since even connections which have not been screwed tight can be secured with this system, further applications are possible, namely for adjusting bearing clearances (e.g. in tapered roller bearings) or for fitting (e.g. spring forces). |
