Clinching stud bolt with Flush head "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 products become more functional and the number of components increases, 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 tightened 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 manufacturing 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.
