Synopsis on Multi-Nut opener



Multi-nut opener


A nut is a type of fastener with a threaded hole. Nuts are almost always used opposite a mating bolt to fasten a stack of parts together. The two partners are kept together by a combination of their threads’ friction, a slight stretch of the bolt, and compression of the parts. In applications where vibration or rotation may work a nut loose, various locking mechanisms may be employed: Adhesives, safety pins clockwise, nylon inserts, or slightly oval-shaped threads. The most common shape is hexagonal, for similar reasons as the bolt head – 6 sides give a good granularity of angles for a tool to approach from (good in tight spots), but more (and smaller) corners would be vulnerable to being rounded off. Other specialized shapes exist for certain needs, such as wing nuts for finger adjustment and captive nuts for inaccessible areas.
Nuts are graded with strength ratings compatible with their respective bolts; for example, an ISO property class 10 nut will be able to support the bolt proof strength load of an ISO property class 10.9 bolt without stripping. Likewise, an SAE class 5 nut can support the proof load of an SAE class 5 bolt, and so on.
A wide variety of nuts exists, from household hardware versions to specialized industry-specific designs that are engineered to meet various technical standards.

Material Required:

  • Dc motors
  • Angle frame
  • metallic structure
  • nut openers
  • Two way switches
  • wires
  • 12 volts dc battery


When give power supply to the dc motors by using 12 volts dc battery the dc motors start rotating in anti-clock directions so that we could be able to open the nuts with ease. The dc motors are attached with the angle frame. We have attached a nut opener structure with the Dc motors. Which is exactly of the same size of the nuts so that can open them in a right manner. So when the dc motors removes in anti-clock direction simultaneously nut opener also start moving in the same direction and start loosening the nuts and at the end the open the nuts in a fine way.


Multi nut opener can be used to open ups the tyres of the cars, trucks and in many places. It will save the time and the cost of the man power and consumer less human energy. It is widely used in industries for nut opening mechanism.


Money saving

Time Saving

Efficiency increasing

More output in less time


After all the testing we are successful in representing our idea of the project in practical way. The project on which we are working is working with very ease and efficient way. We are able to open the multi nuts on the same time.
