How do you investigate the quality and performance of screws? We will introduce it in the "Screw Peripheral Technology Handbook [Inspection and Evaluation Edition]"!

第一工業 第一工業 鋲螺事業部(ネジ・ボルト・ナット等締結部品 製造販売. 静岡県浜松市)
We have published a handbook summarizing "Inspection and Evaluation," which plays an important role in ensuring the performance and quality of screws. Screws are mechanical elements used in various machine structures, and if even one becomes loose, it can lead to damage to the machine structure and pose a risk of serious accidents. Therefore, ensuring the "performance" and "quality" of screws is extremely important to prevent such situations. The "Inspection and Evaluation Edition" of the Screw Peripheral Technology Handbook introduces evaluation tests to ensure the "performance" of screws and inspections to ensure their "quality." If you want to learn more about screw inspection and evaluation tests, please take a look. We have also published the "Material Edition" and "Processing Method Edition" of the "Screw Peripheral Technology Handbook," which were well-received in our newsletter. If you are interested, please check the related information on this page. As a precision screw manufacturer, we handle a wide variety of bolt and nut products. Please feel free to consult us regarding product inquiries or any other concerns you may have. [Contents published *For details, please refer to the catalog.]

Hot press-in type insert (outsert) nut "SSOO nut"

Suppresses deformation of resin products. Special shape that is less likely to slip even under high torque. High pull-out strength also reduces the number of screw components and contributes to weight reduction.

The "SSOO Nut" features fine irregularities on the surface of the shaft to enhance torque resistance performance. It is a heat-pressed insert nut that achieves "difficulty in rotation" and "high pull-out strength." Even when tightened with high torque, it does not slip, preventing damage to resin products. Additionally, its excellent pull-out strength contributes to weight reduction by reducing the number of components. Available sizes include M4, M5, M6, and M8. 【Features】 ■ Shape designed to prevent slipping and rotation, protecting resin products from damage ■ Contributes to weight reduction through the reduction of components and downsizing ■ Torque strength and pull-out strength have been verified through testing ■ Proven track record as an automotive component *You can download PDF materials such as verification test data. For more details on specifications and pilot holes, please feel free to contact us.

SSOI Nut "High Torque Insert Nut"

This is a strong insert nut that prevents slippage (co-rotation and idling) caused by bolt tightening and protects resin products from damage.

Insert nuts for resin (plastic) have traditionally utilized knurled, square, and hexagonal shapes, which have raised concerns about the nuts deforming the resin and spinning freely (slipping or idling) when bolts are tightened with high torque. As a result, we received strong requests from customers to develop insert nuts with shapes that can withstand high torque (high torque strength). We conducted research, development, and prototyping in-house and devised an original shape of insert nut that can handle high torque. It is designed for use during resin molding and also boasts excellent tensile strength (pull-out strength). 【Features】 - Strong nuts that prevent spinning (slipping or idling) and protect resin products from damage. - A unique octagonal shape that enables "high torque tightening," which has not been available before. - We have realized a shape that is difficult to spin, as requested by many customers. For more details, please contact us or download the catalog.

Research, development, testing, and evaluation of fastener products.

Through research and development, we are striving to improve the safety, performance, and quality of our screw products!

Mechanical structures such as automobiles, home appliances, and buildings are assembled by joining multiple parts together. Therefore, joining is common across all industries and is the most fundamental technology for maintaining performance and quality. Joining can be broadly classified into welding through the melting and solidification of metals, chemical adhesion, and mechanical fastening through screws. Each of these methods has many advantages and is an important joining technique, but the only method that allows for high strength and the possibility of disassembly and reuse is mechanical fastening with screws, which is also considered to play an important role in today's environmental issues. Screws are a representative mechanical component that was standardized by ISO early on as a key element of globalization and are widely distributed in the market; however, there are significant differences in safety, performance, and quality among manufacturers. Through diligent research activities to meet users' needs for screw fastening, we are committed to improving the safety, performance, and quality of screw products.
