From soft resin to hard resin! High-strength aluminum fasteners clad in armor.
The "Alu-Arma PT" is a high-strength aluminum alloy tapping screw developed specifically for plastics, capable of tapping into hard resins like PPS and soft resins like PP. Not only does it contribute to weight reduction, but it is also effective in preventing the decrease in axial force after thermal cycle loads, due to aluminum's coefficient of linear expansion being closer to that of plastics than that of iron. 【Features】 ■ Safe material, lightweight, high strength ■ Capable of tapping into hard resin materials ■ Developed a specialized shape as an aluminum fastener for plastics ■ Prevents decrease in axial force due to thermal environmental changes ■ Not affected by magnetic fields *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.
