Eliminate concerns about head jumps during and after construction!! Transform traditional sensory construction into a stable and reliable process.
As a background to the current construction, with the evolution of tightening tools, high rotation and high torque have become possible, leading to a reduction in work time. However, this has also resulted in a greater burden on screws, and issues such as head stripping or screw spinning have become more common. With current tightening tools, it is quite difficult for the operator to maintain a fixed position while tightening, as the fastening force reaches its peak instantaneously. In response to this era of construction difficulties, we have developed a product that can cover these issues with screws. *For more details, please download the catalog or feel free to contact us.*
