Nitto Seiko Co., Ltd. (Headquarters: 20 Umegahata, Ikura-cho, Ayabe City, Kyoto Prefecture, President: Makoto Araga, Tokyo Stock Exchange Prime, https://www.nittoseiko.co.jp/) has newly added a super low thrust model to its single-axis automatic screw tightening machines, which will be available for sale starting February 14, 2025. This product is a single-axis automatic screw tightening machine compatible with small diameter screws in the M2 to M5 class. By minimizing the thrust during screw tightening, it contributes to reducing the load on the workpiece and decreasing issues such as seizing and tightening failures. Additionally, it has advanced thrust control, achieving a reduction in cycle time. 【Features】 1. Reduction of load on the workpiece and decrease in tightening failures 2. Shortened cycle time through advanced thrust control 3. Improved usability and maintenance features

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.

Nitto Seiko Co., Ltd. will add a new low torque model to its high-precision, high-function nut runner: the NX Driver T3 series, with orders starting on August 1, 2024. This product is a nut runner designed for low torque ranges from 0.2 Nm to 0.8 Nm, compatible with small diameter screw sizes of M2 and M3 classes. By implementing data collection and field network functions of the NX Driver T3 series, it will be possible to easily support IoT in low torque screw tightening applications, including ECU boards, home appliances, and precision equipment. Our company will continue to actively develop various high-function models aimed at further improving screw tightening quality.

Nitto Seiko Co., Ltd. has updated two models of the collaborative robot screw tightening unit: PD400 series to comply with CE marking specifications, and will begin sales on February 1, 2024. Among the "Collaborative Robot Screw Tightening Unit: PD400 series," which has been well received since its launch, two models have been updated to CE marking compliant specifications. When launching products within the EU, completed products as machinery require the issuance of CE marking and a Declaration of Conformity, while partially completed machinery requires the issuance of a Declaration of Incorporation. The PD400 series falls under the category of "partly completed machinery" according to the EU Machinery Directive (2006/42/EC). This time, we have prepared Declarations of Incorporation for two models that are in high demand in the European market for Universal Robots and Techman Robots.

Nitto Seiko Co., Ltd. has released the flange-type locking bolt "Cup Bolt TM," which allows for the replacement of bolts incorporating spring washers and flat washers. This new product, which demonstrates a high locking effect, is currently under patent application. Additionally, this product will be sold by both the manufacturer, Kyoei Seisakusho Co., Ltd. (a group company), and our company. The expansion of the product lineup, ranging from small diameter screws to large bolts, embodies the synergy effects of our group, and we will continue to leverage the strengths of a comprehensive fastener manufacturer in our production activities.
