Quantity
The Qishine M20 Threaded Rod is a high-strength fastening solution engineered for critical connections in heavy-duty infrastructure, industrial equipment, and seismic-resistant structures. Manufactured in Suzhou to strict quality controls, this threaded rod combines precision rolling, superior metallurgy, and a robust corrosion-protection system to deliver reliable performance in demanding environments. With a compact 85 mm length and standard M20 coarse pitch, it offers exceptional clamping force while maintaining ease of installation in confined spaces.
Material & Mechanical Properties
Produced from ASTM A193 B7 chromium-molybdenum alloy steel, the M20 threaded rod delivers a minimum tensile strength of 860 MPa and a yield strength of 720 MPa, ensuring resistance to static loads, vibration, and impact stresses. The B7 material also exhibits good toughness at low temperatures, making it suitable for outdoor and seasonal applications. Every batch undergoes tensile, hardness, and dimensional verification to meet ASTM and international fastener standards.

Protective Coating – Hot Dip Galvanized to ASTM A153
Unlike electroplated or mechanically plated alternatives, this Hot Dip Galvanized Threaded Rod features a true metallurgical-bonded zinc coating applied per ASTM A153 – the definitive specification for hot-dip galvanizing on steel threaded components. The HDG coating thickness averages 65–85 µm on the threads, providing outstanding barrier protection and cathodic sacrificial action. This M20 threaded rod withstands salt spray, moisture, chemical fumes, and alkaline environments, delivering a service life exceeding 30 years in moderate corrosive conditions. The hot dip galvanized finish also eliminates hydrogen embrittlement risks often associated with high-strength fasteners.

Application Scenarios
- Bridge and highway construction: anchoring expansion joints, parapet rails, and sign structures.
- Transmission towers and telecom masts: securing base plates and cross-bracing members.
- Industrial platforms and walkways: connecting grating, handrails, and ladder supports.
- Water treatment plants and marine facilities: resisting chloride-induced corrosion in splash zones.
- Prefabricated concrete elements: used as embedment anchors or leveling bolts for precast panels.
- Oil and gas pipelines: supporting clamp assemblies and valve actuators in refinery environments.
