Shinjo Manufacturing Co., Ltd. emerged as a pivotal supplier of nuts to the automotive sector after World War II. Their groundbreaking initiative involved pioneering the cold forming process for weld nuts, a global first that gradually evolved to support large-scale production. Presently, they achieve a remarkable monthly capacity of 100 million units through this innovative cold-forming method.
Their innovation further addressed the industry's need for weight reduction, leading to the development of the PIAS NUT. This solution reinforced thin sheets with exceptional strength, positioning the company as the primary global manufacturer with an automated feeding system. Their market presence extended across Europe and the USA.
In the 1960s, diversifying beyond nuts, the company embarked on manufacturing male screws, marking a historic milestone in screw production. Simultaneously, they secured a patent for self-drilling screws, famously known as PIAS Screw, esteemed globally for its exceptional quality.
The 1990s witnessed another milestone with the introduction of the groundbreaking Bi-Metal Screw, PIASTA, the world's inaugural stainless steel drilling screw penetrating steel sheets, gaining instantaneous global recognition.
Despite the common emergence of competitors with innovative products, Shinjo Mfg. Co., Ltd. remains steadfast in their commitment to continuous innovation, recognizing it as the linchpin in meeting global demands. Their unwavering dedication to elevating quality and honing management capabilities has solidified their status as a premier company.
Operating as the Shinjo Group, they oversee nut manufacturing, while QP Fastening Works Co., Ltd. specializes in screws. Embracing globalization and envisioning their trajectory, they strategically founded Shinjo International Co., Ltd.
While they take pride in delivering world-class products, their paramount focus remains adapting to the evolving landscape and fortifying their capabilities. In pursuit of this goal, they embrace a global perspective, aspiring for Shinjo International Co., Ltd. to act as a conduit to the future, fostering mutual growth and making positive contributions worldwide.
