The "Aluama PT" is a high-strength aluminum alloy tapping screw developed specifically for resin, capable of tapping into hard resins like PPS as well as soft resins like PP. Not only does it contribute to weight reduction, but it is also effective in preventing a decrease in axial force after heat cycle loads due to the aluminum's coefficient of linear expansion being closer to that of resin than iron. 【Features】 ■ Safe material, lightweight, high strength ■ Capable of tapping into hard resin materials ■ Developed a specialized shape as an aluminum fastener for resin ■ 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/
Thin appliances and lightweight cars! No idling, resistant to loosening, and easy torque setting!
"Shinka(R)" is a tapping screw that can accommodate 0.3mm thin plates. Due to its four-thread design, it makes contact with the thin plate at four points, achieving stable fastening. This results in high breakaway (slip) torque, preventing slippage during screw tightening. Additionally, it works effectively with large pitches, allowing for quick fastening. It minimizes damage to valuable thin plate components and reduces product waste due to screw stripping or poor fastening, thereby improving yield. 【Features】 ■ Does not slip or loosen despite fastening thin steel plates ■ Eliminates the need for nut and burring processing ■ Achieves cost reduction and weight savings in fastening *For data and material requests, please feel free to contact us through the Yamashina website: http://www.yamashina.ne.jp/
A rivet stud that allows for strong assembly due to the stop protrusion and retention groove.
"Strux(R)" is a rivet stud that can be easily assembled with a simple press-in device for various metals. The counterpart material flows into the retention groove between the Torx-shaped protrusion and the sizing ring, securing it in place. High retention strength and anti-rotation effects can be expected. It can be manufactured from various carbon steels and stainless steels, and the counterpart materials can include steel, copper, and aluminum. Additionally, designs tailored to customer needs are possible. [Features] - Usable with plating - No special tools required - Compatible with various materials and designs *For data and material requests, please feel free to contact us through the Yamashina website: http://www.yamashina.ne.jp/
Tapping fasteners that provide a strong locking effect when used with all types of resin materials.
"Jushitaito®" is a tapping screw for resin that exhibits high anti-loosening performance even in harsh environments such as thermal changes and vibrations. By placing flutes at positions that divide the circumference into three or four equal parts, almost perpendicular to the screw lead, the screw threads become serrated. After tightening the screw, the resin springs back into these serrations, making it highly resistant to loosening. 【Features】 ■ Screw threads with flutes that are resistant to loosening ■ Low burden on resin due to flutes ■ Large screw pitch ■ Larger screw outer diameter ■ Trust and proven track record *For data and material requests, please feel free to contact us through the Yamashina website: http://www.yamashina.ne.jp/
