1. FABRICATION OF MULTI NUT TIGHTER OR REMOVER
ABSTRACT:
 The main concept of the proposed system is nut fitting & removing without human help for
driving. The heart of the project is motor.. The components used here for efficient function of
individual blocks are Motor, Nut fitting arrangement (spanner) and spur gear arrangement.
WORKING OPERATION:
The project has to give the positive & negative potential to the motor. If we push the
corresponding switch for forward rotation, it helps to fix the nut, or else if we push the
corresponding switch for reverse rotation, the given polarity will be changed oppositely and it
helps to remove the nut. The motor can be operated according to the operator’s
requirement. The electric power can be given by the battery. The operator should lift the model
and place at the appropriate place to tighten or remove the nut.
ADVANTAGES
 Simple in size
 Less weight
 Low power consumption
 Can be operated easily

2. DISADVANTAGES
 It is difficult to remove if rust is formed since it requires high torque to remove nut.
APPLICATIONS
 It is applicable in automobile workshops.
