Product Overview

Hot-dip galvanized expansion screws are high-performance anchoring fasteners made of premium carbon steel. All products are finished with standard hot-dip galvanized surface treatment and manufactured in full compliance with GB/T national standards. Boasting outstanding anti-rust and anti-corrosion capability, they come in complete specifications ranging from M8 to M24 to meet different on-site installation demands. They are widely applied in industrial construction parts, medical equipment, ship and vehicle fittings as well as home decoration projects, playing an essential role in securing overall structural stability and usage safety.

Core Advantages

• Reliable Raw Material: Adopt high-quality carbon steel with strict layered raw material inspection and source quality control. Fine forging processing effectively ensures outstanding structural strength and long service durability.
• Professional Galvanizing Treatment: The integrated hot-dip galvanized layer can well isolate air, moisture and corrosive substances, greatly improving rust resistance and effectively prolonging service life in harsh environments.
• Strict Standard Production: Produced strictly following GB/T industry standards, stable performance and unified specification make quality fully trustworthy.
• Full Range of Sizes: Complete specifications from M8 to M24 are available, matching different drilling apertures and load-bearing standards for flexible installation in various working scenes.
