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 weight reduction 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 radio waves and is not affected by magnetic fields. It is well-suited for automobiles and robots, where weight reduction and electronic control, such as in autonomous driving, are advancing. 【Features】 - Lightweight aluminum alloy - Steel 10.9 bolts break at the threads - From inserts to outserts - Compatible with thermoplastics and thermosetting resins - Blocks radio 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/

basic information
【Other Features】 - A5052, A6056, and A7075 are standard materials, and we can make suggestions based on the required strength and cost. - We can also accommodate other aluminum materials. - A6056 is a high-strength material with proven safety and reliability for automotive bolts. - When inserting a steel bolt with a strength classification of 10.9 into materials like PA66 GF-30 through insert injection molding, the failure mode confirms that the bolt breaks at 10.9. - The adhesion strength with the resin and the strength of the nut itself are sufficient. - We offer various shapes according to molding methods, including insert molding from injection molding or SMC to outsert to bosses. - For outserts, we primarily use ultrasonic press-fitting, along with heat press-fitting and screw-in insertion. - Being made of aluminum alloy, it blocks radio waves and is not affected by magnetic fields. - When used in conjunction with aluminum bolts, it can be effectively utilized in products that need to consider the influence of radio waves and magnetic fields, such as various sensors for autonomous driving and medical devices. - We can accommodate materials including PP and PA, as well as those containing glass fibers and carbon fibers. - We also provide shapes that can be outserted into very hard materials like epoxy resin.

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.
