【No welding or pilot hole required!】Pierce nuts that can be installed simultaneously with press forming.
Shinjo Manufacturing Co., Ltd. - Pierce Nut
No welding, no pre-drilling, no spatter removal! Significant reduction in man-hours, CO2, and power consumption through integrated processing in the pressing process. High torque resistance and water tightness are also achieved.
Are you struggling with the challenges of welding nuts, such as "pre-drilling," "spatter removal," "thermal distortion correction," and "high power consumption or CO2 and oil smoke"? Our "pierce nuts" open holes (piercing) while being fastened simultaneously during the pressing process. This completely eliminates individual welding and insertion processes, as well as handling (material handling), achieving overwhelming process reduction and cost savings. 【Benefits of Implementation】 - Elimination of welding: Contributes to improved working environment and reduction of CO2 emissions and power consumption. - Integrated process: No need for pre-drilling or insertion, making it ideal for automation in progressive press lines. - Stable quality: Prevents forgetting to attach nuts (missing) through electric control, ensuring consistent high quality regardless of who performs the work. - Versatile compatibility: Can be installed on plated steel sheets, aluminum sheets, and painted panels without distortion or burning. Ensures high torque resistance and water tightness, with numerous implementation results from automotive parts to thin sheet housings for distribution boards and control panels! ＼First, please take a look at the materials by downloading the catalog!

basic information
【Features】 - No pre-drilling required: The nut itself creates the hole, eliminating the need for prior processing. - No welding required: Fastening through crimping prevents the generation of welding fumes. - High fastening strength: Piercing plus crimping ensures stable mounting strength. - Labor-saving: Can be combined with automatic supply devices for unmanned installation. - CO₂ reduction: Reduces CO₂ emissions during manufacturing by streamlining processes. We will propose the optimal pierce nut based on steel type, plate thickness, and other factors. 【Our Strengths】 Since its founding in 1959, Shinjo Seisakusho has been providing high-quality products that support manufacturing sites, primarily focusing on the production of fastening components. We offer a "pierce nut system" that includes not only individual pierce nuts but also peripheral equipment such as automatic supply devices and insertion machines, enabling simultaneous rationalization of assembly lines and improvement of quality. We have obtained certifications such as IATF16949 (Quality Management System for the automotive industry) and KES (Environmental Management System), and we are also committed to quality and environmental initiatives.

Company information
Since our founding, our company has been manufacturing screws such as nuts and bolts, along with related products. Screws are functional components that join various parts together to create finished products, serving as the "supporting role." Although they may seem unremarkable, we have continuously made tireless efforts with a spirit of innovation and originality, and as a result, we are deeply grateful to have become a company that can contribute to society, albeit on a small scale. As you know, screws are functional components that gather a wide variety of parts to create finished products. Some products are following a path of advanced lightweight and compact design, while others are becoming more luxurious and larger. On the other hand, the technology for assembling parts is advancing towards high-speed, labor-saving, and even automation. Our company is committed to making continuous efforts in technological innovation, product development, and modernization of equipment to provide technologies and products that can respond to any of these situations. We sincerely ask for your continued support and encouragement.
