Specification

SEODescription

The Φ48-51 expansion bolt is a robust mechanical anchoring solution designed for heavy-duty applications in construction and industrial sectors. This 8x200 expansion anchor features a standard 8mm diameter carbon steel bolt with zinc-plated surface, ensuring corrosion resistance and durability. It supports direct installation into concrete, brick, or masonry substrates within a borehole range of Φ48-51mm. The 200mm length provides deep embedment for high load capacity, delivering up to 12kN tensile strength and 8kN shear strength. Operating temperature ranges from -30°C to +120°C, suitable for both indoor and outdoor environments. Its key advantages include quick installation via hammer-set expansion mechanism and reliable performance in solid base materials, though effectiveness decreases in porous or low-density substrates. Widely used in structural steel connections, machinery mounting, and infrastructure projects requiring secure fastening.
