For High-End International System Windows and Doors • Multi-Functional: Rivetable & Adjustable

In the assembly of high-end international system windows and doors, traditional fasteners often face limitations including single function, restricted installation, and inconvenient adjustment. Standard bolts only achieve connection through tightening, lacking riveting and positioning capabilities, which makes assembly accuracy difficult to control.

Solid rivet bolts can be riveted but feature heavy structures requiring high riveting force, potentially causing damage or deformation to profiles. Additionally, they cannot be readjusted after riveting, negatively impacting sealing performance, opening/closing accuracy, and service life of windows and doors.

To meet strict standards for high-end system windows and doors, STOL Hardware has developed the Stainless Steel Semi-Hollow Rivetable Bolt for global markets, available in M8 and M10 sizes. The innovative design combines semi-hollow structure with adjustable threads, providing dual advantages of rivet fixing and thread adjustment.

• Easier Riveting: Semi-hollow structure requires less pressure, minimizing impact on aluminum profiles and hardware notches
• Stable Positioning: Firm, stable positioning after riveting without shifting
• Post-Rivet Adjustment: Precise fine-tuning of tightness, position, and alignment through standard M8/M10 threads
• Enhanced Durability: High-quality stainless steel construction with excellent corrosion resistance and anti-aging performance
• Multi-Functional: Integrates riveting, locking, and adjusting functions in one fastener

Manufactured from high-quality stainless steel, this product withstands harsh outdoor environments including humidity, temperature changes, and sunlight exposure without rusting, breaking, or failing. It complies with international standards for durability, safety, and appearance in high-end system windows and doors.

Widely applied in various high-end thermal-break aluminum windows, casement windows, sliding windows, lift doors, and other hardware systems.
