[Technical Data Free Offer] You can understand the basics of "Screw Performance Evaluation."
We are engaged in product development and performance evaluation to shape our customers' requests. We provide testing evaluation equipment and examples of evaluations. We will teach you the basics of performance evaluation.
Screws are small components, but they play a significant role as functional parts in "fastening." Performance evaluation is essential to shape our customers' requests. For example, we have a series of screws designed for special octagonal shapes in resin. The starting point was a customer's request for a nut that wouldn't rotate when embedded in resin. Using FEM analysis, we selected the optimal shape from 40 different designs. Collaborating with the production technology and manufacturing departments, we developed an insert nut that can withstand high torque fastening. To turn requests into reality, it is necessary to have evaluation capabilities to ensure proposed performance. During the development stage, we need to consider performance requirements and mass production feasibility, and after development, we must confirm the design performance and mass production quality, among various evaluations. Our company is equipped with various testing and evaluation facilities, including those developed in collaboration with academia. You can understand the basics of screw performance evaluation, including what kind of equipment is used and what evaluations are conducted. We also provide actual evaluation examples. Please take a look at our development and evaluation tests to shape our customers' requests. More details can be downloaded, and feel free to contact us with any inquiries.

Company information
Connecting things to things. We propose the optimal fastening solutions to meet our customers' needs. Behind this proposal capability lies our technical expertise to analyze and evaluate everything from materials to fasteners, our development and manufacturing capabilities to design and produce both bolts and nuts, and our procurement strength with partnerships with 200 cooperating manufacturers. Through the small component of screws, we contribute to the development of various industries. At Daiichi Kogyo, we manufacture both bolts and nuts. Although they are both "screws," the manufacturing processes, equipment, and materials for bolts and nuts are different. We possess the processing equipment and know-how for both. With 60 years of experience in screw manufacturing, as a specialized group that produces both bolts and nuts, we leverage our accumulated know-how to provide the bolts and nuts that our customers need.
