Further weight reduction of resin parts has been achieved! Made of aluminum alloy, it blocks radio waves, is unaffected by magnetic fields, and is suitable for electronic control!
"Alki-Pa" is a series of high-strength, lightweight nuts and collars made from aluminum alloy. It is a fastener developed as a dedicated component targeting the lightweighting of resin applications. Not only is it lightweight, but it also adheres 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, it blocks electromagnetic waves and is not affected by magnetic fields. It is well-suited for automobiles and robots where lightweighting and electronic control, such as in autonomous driving, are advancing. 【Features】 ■ Lightweight aluminum alloy ■ Steel grade 10.9 bolt breaks at the threads ■ From inserts to outserts ■ Compatible with thermoplastics and thermosetting resins ■ Blocks electromagnetic waves and is non-magnetic *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.
