Ideal for use in inserts and outsserts for resin! 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 from aluminum alloy. Developed as dedicated components, these aluminum alloy fasteners target the lightweighting of resin applications. Not only are they lightweight, but they 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 automobiles and robots, where lightweighting and electronic control, such as in autonomous driving, are advancing. 【Features】 - High-strength lightweight nuts and collars made from aluminum alloy - A6056 is a proven high-strength material for automotive bolts, ensuring safety and reliability - 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 such as PP and PA, as well as 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 localize tapping screws in 1954. The company holds data on over 200,000 types of screws and bolts, enabling the high-quality manufacturing of various shaped products. Recently, it has focused on investing in research and development, 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. The company is committed to innovative technological development without being bogged down by history.
