Specification

SEODescription

The Φ8-10 expansion anchor bolt, also known as the Ordinary expansion bolt 8x90 or 8x90 expansion anchor bolts, is a mechanical fastener designed for securing heavy loads in solid base materials like concrete or masonry. With a diameter range of 8-10 mm and a length of 90 mm, it provides reliable anchoring through radial expansion upon installation. This bolt type features a simple one-piece construction, requiring no specialized tools beyond a standard drill for base preparation. Ideal for construction, industrial equipment mounting, and infrastructure projects, it operates within a temperature tolerance of -20°C to 60°C. Key advantages include high shear resistance (typically up to 12 kN in concrete) and corrosion-resistant zinc plating, though its effectiveness depends strictly on proper hole sizing (8-10 mm diameter) and substrate integrity. Limitations include reduced performance in cracked materials and non-adjustability post-installation.

SEOQandA_Product

question:What causes insufficient expansion of the anchor during installation?
answer:Incorrect hole diameter. Use recommended drill size (e.g., 8.5mm) and clean debris from hole thoroughly.
question:Why does the anchor fail to hold under load?
answer:Material mismatch. Verify base material strength and use anchors rated for specific concrete/block strength.
question:How to prevent anchor slippage during tightening?
answer:Apply proper torque. Use torque wrench as per specifications to avoid under/over-tightening expansion sleeves.
question:What causes corrosion in ordinary expansion anchors?
answer:Environmental exposure. Select stainless steel or galvanized variants for damp/high-moisture environments.
question:Why does the anchor protrude excessively after installation?
answer:Incorrect length selection. Measure base material thickness and choose anchor length matching embedment depth requirements.
