en.Wedoany.com Reported - The aerospace fastener market has maintained growth in recent years, driven primarily by increased commercial aircraft production, rising demand for maintenance services, and the expanded application of standardized fastening solutions in civil, military, and space sectors. The growing use of lightweight and advanced materials requires fasteners to ensure structural integrity under severe flight vibrations while reducing weight to optimize fuel efficiency.
Against this backdrop, Growermetal has transformed from a high-quality washer manufacturer into an AS/EN/JISQ 9100 certified aerospace partner, launching the G-Collars product line to offer corrosion-resistant, lightweight, high-performance fastening technologies for the industry.
G-Collars are breakable rings used to connect aerospace structural components, working with threaded pins to form a fastening system that bears shear and tensile loads in aircraft joints. During installation, when the predetermined joint load is reached, a portion of the ring is sheared off in a controlled manner, ensuring correct clamping force without the need for torque control tools. The system achieves a self-locking mechanism through controlled thread deformation or crimping, ensuring anti-loosening under severe vibration conditions and maintaining constant preload throughout the structure's lifecycle.
The G-Collar product portfolio is divided into the standard G-Collar Lock (GWCL) and the lightweight G-Collar Light (GWCST). The standard type provides controlled preload and high strength in joints, suitable for high-load structures; the lightweight type features a reduced profile, offering the same mechanical performance but with lower mass. Leveraging its fully integrated in-house framework, Growermetal can customize special G-Collars according to customer drawings. Weight optimization is achieved through a high-performance material matrix, covering aluminum alloys 2024-T6, 7075-T73, A-286 alloy, as well as 300 series and 17-4PH stainless steel, paired with aerospace coatings such as solid film lubrication, anodizing, aluminum coating, cadmium plating, and silver plating.
After participating in the 2024 exhibition, Growermetal will return to the 2026 Farnborough International Airshow to showcase its full range of fastening innovations in civil aviation, defense, and space sectors. Industry professionals can contact the company's engineering team from July 20 to 24, 2026, at Booth 1014 in Hall 1.
