Developed the clinching stud bolt "JOISTUD(R) -FH"!
Nitto Seiko Co., Ltd. will begin selling the head-embedded clinching stud bolt "JOISTUD(R)-FH," which does not protrude from the fastening member after press-fitting, starting December 1, 2024. *A patent for this product has already been filed.
Clinching stud bolts are widely adopted in many industries, particularly in the automotive sector, and as the functionality of products increases and the number of components rises, there is a growing demand for miniaturization and space-saving designs. Additionally, commercially available low-head clinching stud bolts have experienced issues where the head deforms or sinks when fastened with high torque or subjected to external forces.
In response to this background, we have developed the head-embedded clinching stud bolt "JOISTUD(R)-FH," which leverages the manufacturing technology of industrial fasteners (screws) and mold-making technology cultivated by our company through extensive research. This new product ensures high safety during fastening and prevents the head from protruding after press-fitting into the fastening member. Like conventional products, the new "JOISTUD(R)-FH" can be press-fitted into the fastening member, suppressing head protrusion and reducing head sinking due to axial force during fastening, thereby strongly supporting our customers' manufacturing processes.
