Multi Multi nut remover is a special special purpose tool made to open3close open3close all the nuts of a wheel in one time less effort. lthough various methods of opening nuts are used, but they re1uire a lot of effort to open a single nut one by one. +ith the help of Mult Multii nut nut rem remover over we made made arra arrang ngem emen entt to open open3c 3clo lose se all all the the nuts nuts by amplifying the tor1ue. Different types of gears 4 sprockets are arranged in such a way that if we apply 56m tor1ue with air gun, then we get 7&6m tor1ue as output for combined operation. 8n the work, we concentrate only one application domain i.e. +heels of car" Maruti (wift. 0he main objective of work is to develop a mechanism in one assembly, which can be made in automobiles. 8t can be successfully used as a standard tool  provided with a new new vehicle. lso it can be used in assembly line of automobiles, workshops and service stations. Design is simple, easily workable, and economical and try to satisfy all the aspects of design consideration.
