The study aims to provide industrial equipment such as an AC-powered torque
multiplier. This prototype addresses the problem encountered by mechanics in terms of
loosening and fastening the lug nuts of light vehicles. The objective of this study is to
design and develop an AC-powered Torque Multiplier that can perform tightening and
loosening heavy-duty fasteners with upgraded safety, great precision, and higher levels of
efficiency and productivity. This equipment can help mechanics work smarter through
the customized rotation process that can be designed depending on the needs of the user.
It can be used effectively in areas where space is limited since it is portable and compact.
It is also less expensive than any kind of torque multiplier in the market. Furthermore, it
decreases the damage to threads, nuts, and studs as it’s a much safer alternative to
extended handles or "cheater bars". Furthermore, it has the features of electric operation,
reversible rotation, and ease of operation. It is composed of major components such as a
torque multiplier, gearbox, ac motor, control buttons, and frame.

The result of this study determines that using AC powered torque multiplier
provides a better understanding in terms of its functionality and importance in that
system. The research work was done using the quantitative research method. The study
was conducted on all automotive industry students at the Technological University of the
Philippines Lopez Extension Campus in Lopez, Quezon. Questionnaires were used to
collect data from the students in automotive engineering students of TUP Lopez, Quezon.
