It's been over half a century since the birth of the embedded screw. We offer a variety of combinations!
We would like to introduce our company's "composite components (fasteners + α)." Starting with the "O-ring waterproof screw," which features a groove for setting an O-ring at the bottom of the screw neck to enhance waterproof performance, we also offer products such as the "rubber valve shaft," which has rubber molded onto the head of a metal screw, and the "steel ball press-fit assembly," which incorporates steel balls. Please feel free to consult us when you need assistance. 【Product Lineup (Partial)】 <Fasteners + Resin/Rubber Parts> ■Washer set screws ■Decorative screws ■Heat-resistant screws *For more details, please refer to the PDF document or feel free to contact us.
