Specification

SEODescription

The Φ25-28 Expansion Bolt 8x200mm is a heavy-duty anchoring solution designed for industrial structural applications, featuring a 25-28mm diameter range and 200mm embedment depth. Compatible with standard 8mm installation tools, it supports direct integration into concrete, masonry, or steel substrates without additional adapters. Operating effectively in temperatures from -30°C to +80°C, this ordinary expansion bolt 8x200 excels in construction, bridge engineering, and machinery mounting due to its 25kN+ load capacity and corrosion-resistant coating. Its 25-28mm expansion range ensures versatility across material tolerances, though precise hole alignment is critical. While lacking electrical interfaces, its mechanical design prioritizes shear strength and vibration resistance, making it ideal for permanent installations requiring high stability in harsh environments.
