Our spring toggle wing anchor (butterfly toggle bolt) is made of high‑strength carbon steel (Grade 4.8/8.8) or 304/316 stainless steel (A2-70). The gravity‑activated spring folding wings – after passing through the hollow wall, the spring drives the wings to automatically unfold like a butterfly, spreading the load over a large area against the wall back. The extended threaded shank accommodates various wall thicknesses; the self‑centering anti‑jam mechanism ensures smooth wing deployment. Sizes M4‑M12, shank lengths 50‑200mm custom. Suitable for heavy loads on drywall, hollow bricks, ceiling suspensions, and bathroom hardware. Installation: drill → insert anchor → spring wings deploy automatically → tighten the screw.

01
Spring Toggle Wings Provide Large Bearing Area
Built-in gravity spring drives the wings to automatically expand into a butterfly shape after passing through hollow walls (drywall, hollow bricks, lightweight partitions), closely hugging the back surface with an oversized load-bearing area that evenly distributes weight over a wide wall region. Unlike ordinary expansion sleeves that rely on local friction, this anchor prevents wall crushing or tearing – securely holding heavy bathroom hardware, wall cabinets, or lamps without any risk of pullout.
01
Extended Threaded Shank + Self-Returning Anti-Jam
The extended threaded shank (50-200mm) allows adjustable depth to accommodate wall thicknesses from thin drywall to thick hollow bricks. The patented self-returning anti-jam mechanism ensures smooth wing folding and unfolding even in narrow holes – no tilting or jamming. Simply drill, insert, and the wings deploy automatically – no extra steps, one-person installation, greatly improving on-site efficiency.
01
Multi-Layer Corrosion Protection – Long-Lasting Weather & Wear Resistance
The self-drilling tip features a sharp point design, allowing direct drilling, tapping, and fastening on materials such as metal or wood without pre-drilling, significantly improving construction efficiency. The drilling process is stable with smooth chip removal, minimizing material damage. After fastening, it offers excellent pull-out resistance and vibration resistance, ensuring connections are not easily loosened, ideal for vibration environments or high-strength applications.
