Brass Plain Anchors
Brass Plain Anchors are precision-engineered fastening components designed for strong, reliable, and corrosion-resistant fixings in concrete, solid brick, and stone surfaces. Manufactured from high-grade brass, these anchors offer excellent durability, uniform expansion, and dependable holding strength—making them ideal for electrical, mechanical, and construction applications.
The anchor expands internally when a screw is tightened, creating a firm grip inside the drilled hole. This simple yet effective mechanism ensures high pull-out resistance and secure installation, even in harsh environments or locations exposed to moisture.
Brass Plain Anchors are widely used for mounting electrical switchboards, cable trays, pipe clamps, brackets, and fixtures across commercial, industrial, and residential projects. Their polished brass finish ensures long-lasting performance and a clean, professional installation.
Brass Plain Anchors Key Features
Premium Brass Construction: Rust-free, corrosion-resistant, and suitable for long-term use.
Simple Expansion Design: Ensures firm grip and reliable anchorage in concrete and solid walls.
High Durability: Withstands vibration, moisture, and temperature variations.
Versatile Application: Ideal for electrical fittings, hardware fixtures, support systems, and interior/exterior installations.
Uniform Expansion: Provides strong pull-out resistance and excellent load-carrying capacity.
Easy Installation: Requires only drilling and tightening—no complex tools needed.
