Ideal for use in inserts and outsserts for resins! Compatible with both thermoplastics and thermosetting resins, and we also offer shapes that can be outsserted into very hard materials.
"Alki-Pa" is a series of high-strength lightweight nuts and collars made of aluminum alloy. Developed as dedicated components targeting the weight reduction of resin applications, these aluminum alloy fasteners are not only lightweight but also adhere very strongly when molded into resin, achieving strength that surpasses brass and steel nuts in pull-out and rotation resistance. Additionally, due to the properties of aluminum, they block radio waves and are not affected by magnetic fields. They are well-suited for vehicles and robots where weight reduction and electronic control, such as in autonomous driving, are advancing. 【Features】 - High-strength lightweight nuts and collars made of aluminum alloy - A6056 is a proven high-strength material that is safe and reliable for automotive bolts - For insert applications, ultrasonic press-fitting is primarily used, along with thermal press-fitting and screw-in insertion - Being made of aluminum alloy, they block radio waves and are not affected by magnetic fields - Compatible with materials including PP, PA, and even those containing glass fibers and carbon fibers - Shapes that can be inserted into very hard materials like epoxy resin are also available *For data and material requests, please feel free to contact us through the Yamashina website: http://www.yamashina.ne.jp/

Company information
Established in 1917, during the dawn of mass production of screws in Japan, the company succeeded in producing the first domestic cross-recessed screws in 1949 and cooperated with the government to domesticate tapping screws in 1954. We hold data on over 200,000 types of screws and bolts, enabling us to manufacture a variety of products with high quality. Recently, we have been focusing on research and development investments, working on tapping bolts with a diameter of 6mm or more, high-strength aluminum bolts, tapping screws for thin steel plates, and tapping screws for CFRP, which will support the next generation. We are committed to challenging innovative technology development without being bound by history.
