What Is an Anchor Bolt? A Complete Introduction

An anchor bolt is a heavy-duty fastener designed to attach structural elements to concrete. It transfers loads from a steel frame, column, or machine base into the concrete foundation. Common types include cast-in-place bolts, expansion anchors, wedge anchors, and chemical (epoxy) anchors. They are critical in construction, infrastructure, and industrial applications where safety and load-bearing capacity are non-negotiable. Anchor bolts come in various materials—carbon steel, stainless steel, and galvanized finishes—depending on environmental exposure and load requirements.

Key Factors When Choosing a Chinese Anchor Bolt Manufacturer

质量认证

Ensure the factory holds ISO 9001, CE, or ASTM certifications. These indicate consistent manufacturing processes and material traceability.

材料采购

Verify that the steel used meets your required grade (e.g., Grade 4.6, 8.8, 10.9, or stainless steel 304/316). Ask for mill test certificates.

生产能力

Check minimum order quantities (MOQs) and lead times. Large projects require factories with annual capacities above 10,000 tons.

Surface Treatment Options

Hot-dip galvanizing, zinc plating, Dacromet, or plain finish—choose based on corrosion resistance needs. Confirm in-house or outsourced treatment.

Testing Facilities

Reputable manufacturers have tensile testing, hardness testing, and salt spray testing equipment on-site.

出口经验

Look for factories that regularly export to North America, Europe, or the Middle East. They understand international packaging and documentation requirements.

为何从中国制造商处购买？- 主要优势

  • 成本效益： Chinese anchor bolts are typically 30–50% cheaper than Western equivalents due to lower labor and raw material costs.
  • 大规模生产： China produces over 60% of the world’s fasteners, ensuring supply stability and short lead times.
  • 定制能力： Chinese factories accept custom lengths, diameters, thread types, and head styles with minimal tooling charges.
  • 集成供应链： From steel mills to heat treatment and galvanizing, everything is available within a few hundred kilometers.
  • 灵活的付款条件： Many Chinese suppliers accept T/T, L/C, or even partial credit for long-term buyers.

How to Find a Professional Anchor Bolt Manufacturer in China?

在线 B2B 平台

Use Alibaba, Made-in-China, or Global Sources. Filter by “Verified Supplier” and check transaction history.

Industry Exhibitions

Attend the China Fastener Show (Shanghai) or Canton Fair. Face-to-face meetings build trust and allow factory visits.

第三方审计

Hire inspection companies like SGS, Bureau Veritas, or TÜV to audit the factory before placing large orders.

Sample Orders

Always request samples first. Test the bolt’s tensile strength, thread fit, and coating thickness.

Trade Associations

Contact the China Fastener Industry Association (CFIA) for a list of reputable member factories.

应用场景和解决方案

Industrial Machinery Mounting

Heavy equipment needs precise alignment. Solution: Use chemical anchor bolts with threaded rods and epoxy resin for zero movement.

Solar Panel Mounting Systems

Ground-mounted solar arrays require durable anchors. Solution: Stainless steel expansion anchors with EPDM sealing washers.

Wind Turbine Towers

Extreme loads demand highest reliability. Solution: Custom high-strength anchor cages with Grade 10.9 bolts and ultrasonic inspection.

Top 10 Frequently Asked Questions About Anchor Bolts

  1. What is the difference between a wedge anchor and a sleeve anchor? Wedge anchors expand along the entire length; sleeve anchors expand only at the bottom.
  2. Can anchor bolts be reused? Mechanical anchors lose holding power after removal. Chemical anchors are single-use.
  3. What is the minimum edge distance for anchor bolts? Typically 5 times the bolt diameter for concrete, but check manufacturer specifications.
  4. How do I choose between zinc-plated and hot-dip galvanized? Zinc-plated for indoor use; hot-dip galvanized for outdoor or corrosive environments.
  5. What torque should I use for an M12 wedge anchor? Usually 50–60 ft-lbs, but always refer to the product data sheet.
  6. Are stainless steel anchor bolts stronger than carbon steel? No, carbon steel Grade 8.8 is stronger than stainless 304. Stainless offers better corrosion resistance.
  7. Can I install anchor bolts in wet concrete? Only cast-in-place bolts. Expansion anchors require cured concrete.
  8. What is the shelf life of chemical anchor adhesive? Typically 12–18 months if stored below 25°C.
  9. How deep should an anchor bolt be embedded? Minimum 8 times the bolt diameter for concrete.
  10. Do anchor bolts come with nuts and washers? Most suppliers include them, but confirm in the quotation.

Procurement Considerations for Anchor Bolts

  • Thread Specification: Confirm UNC, UNF, or metric threads. Most international projects use UNC or metric coarse.
  • Length Tolerance: Allow ±2mm for standard bolts. Tighter tolerances increase cost.
  • 包装: For export, demand wooden pallets with steel strapping and waterproof wrapping to prevent rust.
  • Inspection Reports: Request material certificates, tensile test reports, and coating thickness reports before shipment.
  • 交货时间： Standard production takes 20–30 days. Custom orders may take 40–50 days.
  • 付款条款： 30% deposit, 70% against copy of shipping documents is standard.

  10. Can anchor bolts be used in wood? No, use lag bolts or through-bolts with washers for wood.

Customs Data and Tariff Rates for Anchor Bolts

Anchor bolts fall under HS Code 7318.15 (Threaded screws and bolts). The general MFN tariff rate for import into the USA is 0% for most carbon steel bolts. However, Section 301 tariffs may apply if the product originates from China, adding 25% duty. For the EU, the duty rate is typically 3.7% for steel fasteners. Always verify with a customs broker, as rates change with trade agreements and anti-dumping measures. China’s export VAT rebate for fasteners is currently 13%.

为什么选择中小型工厂？与大型工厂的区别
