The known art of nuts & bolts / screws (which are the essential components of most of the mechanical fastenings) have serious drawbacks in tightening / loosening the same. The 4 variations of invented winged nuts (Ref. Drawing No.4) have optional perpendicular / parallel positioning & proportionate extension of wings, added feature of square / hexagonal headed base of the nut to facilitate its manoeuvre-ability by spanner also, have thumb-shaped more comfortable grip & an overall ‘easier & more torque producing’ economical design.
The dual engraving design of the invented bolts & screws (Ref. Drawing No.5) facilitates additional manoeuvre-ability
Thus, these invented nuts & bolts / screws are more easily manoeuvreable, with or without tools, have more economical values (will save trillions of rupees in just few years of mass production) & mechanically more effective designs, provides effective solutions to user’s problems, are easily implementable & test-able, thus, have tremendous utility & business values, & thus, a huge scope for industrial application as well.
