The Φ19-22 expansion bolt, specifically the Ordinary expansion 8x60 model, is a robust 8x60 steel anchor designed for heavy-duty mechanical fastening in construction and industrial sectors. It accommodates base material hole diameters of Φ19-22mm and features a 60mm embedment depth with an 8mm diameter steel shaft, ensuring high tensile strength and shear resistance. This anchor operates in ambient temperatures ranging from -20°C to +80°C and requires no electrical input or communication interfaces, relying purely on mechanical expansion for installation. Ideal for securing structural components, machinery, and fixtures to concrete or masonry, it offers rapid installation and corrosion-resistant properties. Key advantages include durability under dynamic loads and cost-effectiveness, though precise hole alignment is critical to avoid reduced holding capacity. Its simplicity suits applications requiring reliable, non-specialized anchoring solutions.

SEOQandA_Product

question:Insufficient or excessive torque during installation?
answer:Use a calibrated torque wrench and follow manufacturer's torque specifications precisely.
question:Material corrosion in harsh environments?
answer:Select corrosion-resistant materials like stainless steel or galvanized bolts for such conditions.
question:Improper pre-drilled hole sizing?
answer:Verify hole diameter matches bolt specifications (typically 1-2mm larger than bolt diameter).
question:Bolt loosening under vibration?
answer:Ensure clean installation surfaces and proper torque. Consider thread-locking adhesive if needed.
question:Inadequate load-bearing capacity?
answer:Confirm bolt specifications meet application requirements; upgrade to higher-grade hardware if necessary.
