The Φ70-76 ordinary expansion anchor (8x100mm) is a robust mechanical fastener designed for heavy-duty anchoring in concrete, masonry, and solid stone substrates. This 8x100mm ordinary expansion bolt features a Φ70-76mm outer sleeve diameter range, optimized for secure installations requiring 8mm thread diameter and 100mm embedment depth. It operates under standard industrial temperature ranges (-20°C to +60°C) and withstands axial loads up to 12kN in concrete C20/25. The galvanized steel construction ensures corrosion resistance in construction, infrastructure, and industrial equipment applications. Its wedge-style expansion mechanism provides reliable vibration resistance but requires precise 8mm pilot hole drilling. While offering superior pull-out strength in dense materials, performance diminishes in porous substrates. Key applications include structural steel connections, machinery mounting, and utility bracket installations.

SEOQandA_Product

question:Installation difficulty with Φ70-76+Ordinary expansion 8*100.
answer:Ensure correct drill bit size (8mm) and use proper installation tools.
question:Mismatch between pipe and expansion sleeve dimensions.
answer:Verify pipe OD is within 70-76mm and expansion sleeve is 8*100mm.
question:Expansion sleeve material strength concerns.
answer:Use carbon steel or stainless steel sleeves for higher load capacity.
question:Insufficient anchoring force after installation.
answer:Check hole depth (≥100mm) and ensure full sleeve expansion.
question:Corrosion in harsh environments.
answer:Replace ordinary sleeves with stainless steel for corrosion resistance.
