Design and fabrication of adjustable spanner / Muhammad Amyrul Azri Mohd Zain

An adjustable spanner is a tool that used to tighten or loosen a bolt and nut. The idea to fabricate adjustable spanner come because of workers require spanners of different sizes to tightening or loosening nut and bolt. Besides, workers need a lot of tools to carry to workplace as there are no tools that can facilitate them. The objectives of this project are to design an innovation of existing adjustable spanner and to fabricate a spanner that can speed up the work of tightening and loosening. As a result of this project, the objectives were achieved, and the project went as planned but this innovation also has its own advantages and disadvantages. So new innovations must always be created in order to produce a quality and efficient adjustable spanner based on existing innovations.
