SITUO Hardware – Stainless Steel Semi-Hollow Rivetable Bolt (M8/M10)
For High-End International System Windows and Doors • Multi-Functional: Rivetable & Adjustable
In the assembly and application of high-end international system windows and doors, traditional fasteners often suffer from limitations such as single function, restricted installation, and inconvenient adjustment.
Standard bolts can only achieve connection by tightening, without riveting and positioning functions, making it difficult to control assembly accuracy. Solid rivet bolts, although able to be riveted, feature a heavy structure that requires high riveting force, easily causing damage or deformation to profiles. Moreover, they cannot be readjusted after riveting, which seriously affects the sealing performance, opening/closing accuracy, and service life of windows and doors.
To meet the strict standards of high-end system windows and doors, STOL Hardware has specially developed the Stainless Steel Semi-Hollow Rivetable Bolt for the global market, available in M8 and M10.
With its innovative design combining a semi-hollow structure and adjustable threads, it breaks through the limitations of traditional fasteners and delivers the dual core advantages of rivet fixing + thread adjustment, making it the ideal fastening solution for high-end window and door assembly.
Featuring a semi-hollow structure, this bolt is easier to rivet, more stable in forming, and more efficient in assembly compared with solid rivet bolts.
The semi-hollow design effectively reduces the pressure required for riveting, minimizing impact and damage to aluminum profiles and hardware notches.
After riveting, it provides firm, stable, and non-shifting positioning, perfectly matching the high-precision, high-efficiency requirements of automated production lines for high-end system windows and doors, greatly improving production efficiency and product yield.
Unlike standard bolts that only tighten and cannot rivet, STOL’s rivetable bolt enables the innovative workflow: rivet first, adjust later via threads.
Even after riveting, precise fine-tuning of tightness, position, and alignment can still be made through the standard M8/M10 threads.
This solves the industry pain point that traditional riveted components are fixed permanently and cannot be modified, facilitating accuracy correction, sealing adjustment, and maintenance during production, installation, and later use, significantly enhancing overall stability and user experience.
Manufactured from high-quality stainless steel, this product provides excellent corrosion resistance, anti-aging performance, and high strength.
It withstands harsh outdoor environments including humidity, temperature changes, and sunlight exposure without rusting, breaking, or failing, fully complying with the high international standards for durability, safety, and appearance in high-end system windows and doors.
It is widely applied in various high-end thermal-break aluminum windows, casement windows, sliding windows, lift doors, and other hardware systems.
From production and assembly to on-site installation, from initial commissioning to long-term use, one fastener integrates riveting, locking, and adjusting functions.
It reduces component variety, improves installation efficiency, and optimizes usability.
While standard bolts can only tighten and solid bolts are hard to rivet,
STOL Semi-Hollow Rivetable Bolts stand out with:
easier riveting, adjustable performance, multi-functionality, and higher durability.
