Situo Hardware specializes in manufacturing 304 stainless steel hinge rivets, window sliding stay rivets, smart lifting support pins, and precision articulated fasteners. Our products serve system windows, broken bridge aluminum windows, smart window openers, electric lifting supports, and intelligent window hardware systems.

This product series comprises professional integrated precision fasteners designed for window sliding stay hinges and smart lifting mechanisms. All components are CNC machined from solid 304 stainless steel, ensuring high concentricity, uniform fitting clearance, and smooth, silent operation. Optimized for dynamic working conditions, these fasteners provide high-strength fastening and flexible articulation for casement windows, hung windows, curtain wall window hinge joints, and smart lifting support mechanisms.

• Premium 304 Stainless Steel: Genuine SUS304 stainless steel with excellent rust resistance, oxidation resistance, and salt spray corrosion resistance for outdoor, humid, and coastal environments.
• Precision CNC Integrated Machining: One-time CNC turning and milling ensures tight tolerances, burr-free surfaces, and smooth operation with excellent anti-fatigue performance.
• Dual Functions of Load-Bearing & Articulation: Solid integrated structure provides rigidity for bearing sash weight and lifting loads while ensuring flexible joint rotation and telescopic adjustment.
• Wide Versatility: Suitable for sliding stay rivets, hinge rivets, and smart lifting support positioning pins across various window types and intelligent hardware systems.
• High-Precision Positioning: Strict dimensional tolerance control eliminates shaking, uneven gaps, and poor closing problems while maintaining operational accuracy.
• Full Non-Standard Customization: Customizable diameter, length, step structure, eccentricity, head shape, and limit grooves to meet specific requirements.
• Strict Quality Control: Comprehensive quality assurance including material inspection, dimensional verification, concentricity detection, and dynamic operation testing.

• Articulated fixing rivets for sliding stay hinges of broken bridge aluminum casement windows, hung windows, and curtain wall windows
• Movable joint connecting pin accessories for architectural window hardware and ordinary aluminum alloy windows
• Positioning pins for smart window openers and electric lifting window automatic support mechanisms
• Limit articulated fasteners for intelligent window lifting support rods and telescopic support arms
• Rust-proof weather-resistant hinge pins and rivets for outdoor engineering windows and coastal salt spray environments
• Precision connecting parts for intelligent automatic window equipment and dynamic transmission mechanisms

We specialize in custom processing of precision window rivets and smart equipment shaft pins, supporting both machining and cold forging processes. Our comprehensive workflow includes material screening, CNC precision machining, polishing, dimensional inspection, dynamic performance sampling, and packaging.
