Complete abolition of lower hole processing and welding processes, and environmental measures.
When using widely recognized welded nuts, there are many challenges, including the burden on the work environment during the welding process, CO2 emissions issues, and various tasks related to processes before and after welding, as well as material handling. Our pierce nuts do not require pre-drilled mounting holes; instead, they pierce the metal panel while being crimped and installed during the pressing process, eliminating the need for welding and the associated CO2 emissions. 【Application Scenarios】 - Mass production lines for automotive parts: Areas where fastening is desired for pressed components such as body structure parts and seat frames. - Thin-walled enclosures for distribution boards and control panels: Compatible with plated steel and aluminum sheets. Products that want to avoid "burns" and "paint peeling" caused by welding. - Automated lines using progressive presses: Completing fastening simultaneously with press forming, aiming to completely eliminate standalone insertion processes and handling (material handling). - Worksites struggling with finishing tasks (post-process): Production sites that require significant labor for removing spatter and burrs after spot welding and correcting thermal distortion. - Worksites facing issues with dependency on skilled labor: Installation requires only the ability to operate the press machine. Consistently high-quality installation is possible regardless of who performs the work.

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 and plate thickness. 【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.
