Description:FIELD OF INVENTION
The present invention relates to the bolt and nut makeup machinery field. More particularly the invention relates to the structure of a square tower bolt and its unique function of moving a square rod inside the square section.

BACKGROUND OF THE INVENTION
A tower bolt is a fastener to secure a first structure to a second structure. The first structure may include doors, gates, and windows, and the second structure may include walls and frames. The tower bolt is mounted on the first structure and includes a rod attached to a knob. The knob may displace the rod into a strike plate mounted on the second structure, thereby securing the first structure to the second structure. Manufacturing process of the tower bolt from a cylindrical shaped tower bolt can be a bit time consuming and hard.
Cylindrical tower bolts may have limitations in torque transmission. The circular cross-section of a cylindrical bolt provides less surface area for applying force, resulting in potentially lower torque transmission. This can make it more challenging to tighten or loosen the bolt with the same level of torque as a square-shaped bolt. Also, the cylindrical tower bolts are more prone to rotation or slippage during use. Due to their cylindrical shape, they may have a tendency to rotate or turn unintentionally, especially if there are external forces or vibrations acting on the bolt. This can potentially lead to a loss of alignment or a weakened connection, affecting the overall strength and functionality of the bolt. The circular cross-section requires additional clearance or gaps around the bolt to accommodate its shape. In certain applications where space optimization is crucial, such as compact designs or close proximity installations, the cylindrical shape may result in wasted space or inefficient utilization of available area.
Owing to the above disadvantages the present inventors have come up with a unique square shaped tower bolt, which is free from any defects, finished to the correct shape and have smooth action. In the present invention the efficiency improved and the labor strength is reduced. Moreover, the sleek and unique appearance makes it more appealing.
