Specification

SEODescription

The Φ38-40 expansion series includes the Ordinary expansion 8x50 model, a mechanical anchoring solution designed for heavy-duty industrial applications. This expansion bolt 8x50 features a standardized M8 thread and 50mm embedment depth, optimized for fastening in concrete, masonry, or solid stone substrates. With a load capacity of up to 12kN in static tension and corrosion-resistant zinc plating, it operates reliably in environments ranging from -30°C to +120°C. The bolt requires a 14mm pre-drilled hole for Φ38-40 diameter compatibility and integrates seamlessly with structural supports, machinery bases, and pipeline brackets. Widely used in construction, energy infrastructure, and manufacturing sectors, its key advantages include rapid installation and vibration resistance, though precise hole alignment is critical for optimal performance. Limited to non-dynamic load scenarios.

SEOQandA_Product

question:Incorrect hole size for Φ38-40 expansion bolt installation?
answer:Verify drill bit matches bolt diameter; adjust hole size to ensure snug fit for expansion.
question:Bolt slipping or failing to anchor securely?
answer:Ensure base material (e.g., concrete) is solid; avoid hollow or cracked substrates.
question:Difficulty tightening the 8*50 expansion bolt fully?
answer:Check hole depth (min. 55mm); clear debris to allow full bolt insertion and expansion.
question:Bolt corrosion in humid environments?
answer:Use stainless steel variant or apply anti-corrosion coating for moisture resistance.
question:Shearing under load after installation?
answer:Confirm load capacity matches requirements; redistribute weight or use higher-grade bolts.
