Product details

Our galvanized carbon steel toggle bolt belongs to core construction Bolt fastener series, specially engineered for hollow substrate fixing scenarios that regular expansion anchors cannot support. Equipped with flexible metal spring butterfly wings, this anchor bolt automatically expands inside hollow walls after installation to form a firm locking structure, providing stable heavy-load fixing force on gypsum drywall, hollow brick, ceiling board and cavity partition walls. All raw materials adopt high tensile carbon steel, matched with standardized bolt thread processing, zinc plating anti-rust surface treatment, fully compliant with international construction fastener standards for wholesale importers, hardware distributors and engineering brand OEM cooperation. As factory direct supply fastener, we provide complete size series and customized service for global bulk procurement customers, effectively reducing downstream purchasing cost and shortening supply cycle.

✔ Built-in elastic steel spring wing, automatic opening inside hollow cavity for double-sided clamping fixing

✔ Multi-size thread specification coverage M4-M10, customizable bolt length for different wall thickness

✔ Double anti-rust galvanized surface treatment, long service life in humid indoor and semi-outdoor environment

✔ High tensile carbon steel raw material, strong load bearing capacity for lamp, cabinet, decorative bracket mounting

✔ Simple installation process, only one drill hole needed without secondary wall reinforcement

✔ Complete OEM private label service, customizable packaging and logo marking for brand merchants

✔ Stable mass production capacity, continuous bulk order delivery without stock shortage risk

This spring wing toggle bolt is manufactured from high-quality cold drawn carbon steel wire and cold rolled steel sheet as raw materials, all incoming materials pass tensile strength and anti-rust laboratory test before entering production line. The production flow includes precise thread rolling, wing stamping forming, spring bending assembly and automatic galvanizing treatment four core working procedures. Thread rolling processing ensures uniform thread pitch, smooth screwing without sliding teeth during installation; butterfly wing adopts integrated stamping molding technology, no welding gap, strong spring resilience after repeated compression. Surface electro galvanizing process forms compact zinc protective film on bolt and wing surface, effectively isolate air moisture to avoid rust and oxidation, greatly extend service life in damp construction environment.

Strict multi-stage quality control system is implemented throughout production: first inspection of raw material hardness, semi-finished thread size sampling inspection, finished product load pull test before packaging, each batch retains test report for customer inspection. Compared with plastic expansion plugs, metal toggle bolt owns higher load bearing limit, not easy to break or fall off under heavy object weight, which makes it the preferred cavity wall fastener for construction hardware wholesale merchants. For special environment demand, we can switch raw material to 304 stainless steel to upgrade corrosion resistance for coastal high humidity export markets.

This industrial Bolt toggle anchor widely fits multi B wholesale procurement scenarios:

Hardware Wholesale Merchants: Bulk stock supply for offline hardware retail shops, building materials market distributors
Global Retail Chain Brands: Standard size assort packaged fastener sets for supermarket hardware shelf sales
Construction Engineering OEM Manufacturers: Custom specification fastener matching wall decoration, ceiling lamp, wall cabinet installation kits
Furniture & Decoration Factories: Supporting fixed fasteners for suspended cabinet, wall hanging shelf, decorative light fixture assembly
Overseas Import & Trading Companies: Mixed container bulk order mixed with other Bolt and Nut hardware products to optimize container utilization rate
