SUS304 Stainless Steel High Precision Articulated Rivet and Lifting Pin for

Situo Hardware manufactures high-quality SUS304 precision articulated rivets, smart support lifting pins and casement window sliding stay pins. These products are specially developed for system window hardware assembly, intelligent window lifting structures and mass window hardware supporting projects, widely used in residential decoration, architectural engineering and intelligent window equipment assembly.

This series of SUS304 precision window fasteners integrates articulated riveting, sliding positioning and lifting support functions. Made of genuine SUS304 stainless steel, it features low tolerance, high coaxiality and smooth movement. Optimized professionally for window hardware assembly stability and lifting positioning accuracy, it effectively solves common assembly problems such as jamming, shaking, offset and uneven sealing after window installation.

With excellent weather resistance and rust resistance, it adapts to indoor and outdoor window working conditions. Supported by dual production processes of machining and cold forging, the products support standard mass production and non-standard custom processing, serving as high-precision matching fasteners for high-end window hardware assembly.

Manufactured strictly in accordance with system window hardware assembly standards, the products perfectly match mainstream sliding stays, support arms, window openers and hinge structures. No secondary grinding or hole expansion is required, which greatly improves the mass assembly efficiency of window factories and adapts to pipeline batch production.

Adopting high-precision coaxial processing technology, the pins maintain uniform and smooth rotation. Batch assembled windows present consistent opening and closing handfeel without jamming or stuck points, effectively reducing after-sales debugging pressure and improving overall project installation quality.

Optimized for intelligent window lifting and telescopic working conditions, the positioning surface is flat and the limit accuracy is high. It ensures no offset, no jitter and no displacement during window lifting, stretching and hovering, precisely matching the stroke of electric window openers and maintaining long-term stable operation of intelligent lifting systems.

Made of original SUS304 stainless steel with pure texture, it has excellent salt spray resistance, moisture resistance and oxidation resistance. It is not easy to rust or jam after long-term outdoor and wall exposure, ensuring long-term stable operation of window hardware and meeting high-standard supporting needs of fine decoration and architectural engineering projects.

Support dual production modes: cold forging for standard specifications with fast delivery and high cost performance for mass orders; CNC machining for high-precision and special-shaped non-standard products to meet personalized structural requirements. The specific production cycle can be confirmed with customer service according to the order situation.

Unified batch precision and strong interchangeability realize quick assembly without repeated debugging. It fundamentally avoids common after-sales problems such as window shaking, abnormal noise, air leakage and poor closing, helping manufacturers save labor assembly cost and after-sales maintenance cost.
