Brief Description (with Parameters and MOQ)

Expansion Bolts (also known as expansion anchors) are mechanical fasteners that secure objects to concrete, brick, or stone by expanding a sleeve or plug when tightened. Ideal for heavy-duty applications, they consist of a threaded bolt, expansion sleeve, and nut, providing secure hold in non-wood substrates. Manufactured from carbon steel (zinc-plated), stainless steel (304/316), or galvanized steel for durability.

- Stainless Steel (304/316 for corrosion-prone environments).
Size Range:
- Diameter: M6–M24 (metric) / 1/4"–1" (imperial).
- Length: 30–200 mm (embedment depth varies by substrate).
Design:
- Sleeve Types: Split sleeve (standard), drop-in anchor, or wedge anchor.
- Head Style: Hex head, countersunk, or flat head.
Load Capacity:
- Tensile Strength: 500–2,000 kg (depending on size and material).

Factory Advantages: ISO-certified production, load test reports, support for non-standard lengths, corrosion-resistant coatings (e.g., Dacromet), and bulk orders with lead times of 10–25 days.
