Stone Expansion Anchor
These stone expansion bolts are made from high-strength metal materials, providing excellent load-bearing performance and secure fastening. Suitable for stone, marble, concrete, brick walls, and other hard surfaces, they expand firmly after installation to ensure long-lasting stability. Ideal for railings, brackets, curtain walls, machinery mounting, and home improvement projects. 🏗️

PRODUCT FEATURES
- 💪Heavy-Duty Load Capacity
Made from thickened high-strength metal, these expansion bolts offer excellent tensile and compression resistance. Once installed, they expand evenly for a stronger grip, ensuring stable fastening even under heavy loads or vibration conditions.

- 🔩Precision Expansion Structure
The precision-engineered expansion sleeve expands quickly and evenly during tightening, greatly increasing friction against the wall surface. This provides stronger fixation and prevents loosening or slipping over time.

- 🛡️Rust & Corrosion Resistant
The whole body is finely processed by hot galvanizing to isolate air and water vapor erosion, resist humid and rainy environment, effectively prevent rust and oxidation, keep intact for long-term indoor and outdoor use, and greatly extend service life.

- 🔧Easy & Efficient Installation
The smart geometric design allows for a higher tolerance in hole circularity. Simple drilling, cleaning, hammering, and tightening are all it takes to complete the fixture. It significantly boosts installation efficiency for both large commercial construction sites and home DIY projects.

- ⚙️Wide Application Range
Suitable for stone, marble, concrete, brick walls, and other hard surfaces. Perfect for railings, machinery fixing, signboards, brackets, air-conditioner mounts, and various construction or home installation projects.

HOW TO USE
1. Drill a 6mm hole in the wall with a matching drill bit.
2. Insert the expansion anchor fully into the drilled hole.
3. Tighten the screw into the anchor with a screwdriver to expand and secure it.
4. Installation is complete — your anchor is ready for use.
