Introducing common questions regarding screw structures in waterproof design and points to consider during their examination!
★★Shirutoku Report: Useful Information You Should Know★★ When designing for waterproofing, many people tend to focus solely on the gasket parts of the housing. In fact, the screw areas require even more attention than the main waterproof sections. This report discusses the screw structures in waterproof design and points to consider during their examination, addressing frequently asked questions. Please take a moment to read it. 【Contents】 ■ Services we have received inquiries about ■ Frequently asked questions - What specifications should be applied for waterproof screws? - What is the most important point to be cautious about when using waterproof screws? *For more details, please refer to the PDF document or feel free to contact us.
This is a special screw that allows for a consistent fastening, as the head of the screw will strip at the optimal torque when tightened.
This is a special fastening component that causes the screw head to shear off at the targeted torque when tightened. Since it is fundamentally a screw, it is held in place by axial force. ■ Even with variations in tightening methods, consistent fastening can be achieved. ■ It prevents over-tightening. ■ The screw head shears off at the end of fastening, allowing visual confirmation of completion. ■ Specifications can be set for easy removal with pliers or similar tools. ■ It prevents tampering or unauthorized loosening. *For data or material requests, please feel free to contact us through the Yamashina website: http://www.yamashina.ne.jp/
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/
For thinner home appliances and lighter cars! No idling, resistant to loosening, and easy torque setting!
"Shinka(R)" is a tapping screw that can accommodate thin plates of 0.3mm. With 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 waste due to screw stripping or fastening failures, thereby improving yield. 【Features】 ■ Does not slip or loosen even with thin steel plate fastening ■ 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/
Tapping fasteners that provide a strong locking effect for use with all types of resin materials.
"Jushtite®" 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 the screw is tightened, 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/
Metal thread rolling fasteners that achieve the removal of tapping processes and improve fastening quality.
The "TAPTITE 2000(R)" is a metal tapping fastener developed by CONTI/REMINC, particularly effective for tapless applications with diameters of M6 and above. The bolt cross-section has a trilobular shape, which allows for easy screwing in with low torque. After screwing in, the tight fit with the mating material and the effect of spring back make it resistant to loosening. This bolt has been standardized and widely used by many Western automobile manufacturers, including Mercedes, Volkswagen, BMW, Renault, Ford, and GM, demonstrating its proven track record. 【Features】 ■ Trilobular thread shape ■ Female thread formation through rolling ■ Prevention of diagonal entry ■ Wide range of applications *For data and material requests, please feel free to contact us through the Yamashina website: http://www.yamashina.ne.jp/
