Wedge Anchor Bolt — M12 / M16 / M20

1. Product Overview

The Wedge Anchor Bolt (M12/M16/M20) is a high-grade, fully threaded stud-type mechanical anchor designed for secure fastening in solid concrete and grout-filled masonry. Its primary industrial use is heavy-duty anchoring for structural steelwork, machinery mounting, pipe supports, curtain walls, and safety railings in construction and industrial facilities. The key value proposition is its uniform holding capacity that increases as tension is applied, thanks to a three-segment expansion clip ensuring reliable load distribution. Strategically, this product is critical for global infrastructure projects requiring certified, vibration-resistant anchoring with fast installation and long-term durability in C20+ concrete.

2. Key Specifications & Technical Characteristics

• Material Components: Carbon steel (grade 4.8/8.8/10.9) or Stainless Steel 304 (A2) / 316 (A4)

• Grade/Purity: Carbon structural steel per GB/ASTM/DIN/JIS standards; Stainless steel A2/A4 grade

• Physical Characteristics:

  • Form: Fully threaded stud with three-segment expansion clip, nut, and washer included

  • Diameter sizes: M12, M16, M20 (also available M6–M24)

  • Length range: 50 mm – 200 mm (customizable up to 5000 mm)

  • Surface finish: Zinc plated (≥5μm), Blue-White/Color zinc plate, or Hot Dip Galvanized (≥45μm)

  • Color: Silver (stainless), Brown/Zinc-tone (carbon steel)

  • Tensile strength: 400–800 N/mm² (grade-dependent)

  • Pull-out load capacity: 1,150–12,380 kg depending on size and concrete strength

• Packaging Options: Carton + pallet, box, or bag; bulk packaging available for 20MT orders

• Shelf Life: Indefinite when stored dry; corrosion-resistant finishes ensure long-term storage stability

3. Core Industrial Applications

Why it outperforms alternatives: Wedge anchors deliver superior pull-out strength compared to sleeve anchors in solid concrete, with uniform expansion ensuring consistent holding capacity across all installed units. The metric system (DIN/ISO/GB) ensures global compatibility, while HDG finishes extend service life in corrosive environments.

4. Competitive Advantages

• Quality Consistency: Manufactured to DIN/ANSI/GB/ISO/JIS standards with ±0.01–0.05mm tolerance; every batch tested for tensile strength and pull-out load

• Supply Reliability: MOQ of 100 pieces for samples; bulk 20MT orders fulfilled within 25–30 days from Shanghai/Ningbo ports

• Logistics Capability: Optimized container loading (20MT per 20′ container); palletized carton packaging minimizes damage during transit

• Price Competitiveness: Bulk pricing available; carbon steel variant at ₹8/piece (~$0.10) with customization options

• Sustainability Benefits: Hot-dip galvanized (≥45μm) and zinc-plated finishes reduce environmental corrosion; recyclable steel material

• Technical Support: 48-hour after-sales response; 12-month warranty; installation parameters (hole diameter, depth, torque) provided per size

This product represents a strategic sourcing decision for enterprises requiring certified, high-load anchoring with predictable performance across global projects.
