Octa Lobular Series SSOO Bolt SSOO Nut PLUS SSOO Nut SSOI Nut
Are you having trouble with "fastening resin"? You can fasten resin with "bolts + nuts." You will gain basic knowledge about screws specifically for resin.
Are you struggling with "fastening of resin"? With resin, you can achieve fastening using "bolts + nuts" by utilizing dedicated screws. Dedicated screws include insert nuts and insert bolts that are embedded in the resin. In softer resins compared to iron, embedded bolts or nuts can rotate together, leading to deformation or breakage of the resin. Have you ever experienced deformation of resin products due to "nut rotation"? Our original development of dedicated screws for resin (Octa Lobular(R) series) features a special octagonal head shape that ensures high torque resistance and high pull-out strength. Even when tightened with high torque, it prevents "rotation" and "pull-out," protecting resin products. You can choose from various types of insert nuts (simultaneous molding type, press-fit type, and both with caps) and insert bolts (both simultaneous molding and post-embedding options) according to your specifications. If you're wondering, "What is an insert nut?" please refer to our technical document "Basic Knowledge of Insert Nuts." It clearly explains the usage of insert nuts and compatible resins, covering the "basics of insert nuts." You can view it via PDF download.

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.
