A Threaded Rod (also known as All Thread Rod or Fully Threaded Rod) is a headless cylindrical fastener with continuous external threading along its entire length. Unlike bolts with a fixed head, threaded rods allow nuts to be positioned anywhere along the rod, providing unmatched flexibility for adjustable fastening, anchoring, and structural connections. They can be easily cut to custom lengths on-site, making them an essential component across construction, infrastructure, mechanical assembly, and heavy machinery industries. [19†L2-L6]

At Shanghai Malaxy Industry Co., Ltd. , we manufacture precision-engineered threaded rods conforming to DIN 975, ASTM A307, and ASTM A193 standards, with ISO 9001:2015 quality management certification. As a leading fastener manufacturer based in Shanghai—one of the world’s largest fastener production and export hubs—we offer competitive pricing, rapid lead times, and full compliance with international standards.

Key Specifications

Material & Strength Grades

Carbon Steel Threaded Rods

• Grade 4.6 / 4.8: General purpose, tensile strength 400–580 MPa, suitable for light to medium structural applications (hanging systems, conduit supports, general fastening).

• Grade 8.8: High-strength, tensile strength 800–900 MPa, ideal for heavy machinery, structural steel connections, and industrial equipment.

Alloy Steel Threaded Rods – ASTM A193 Grade B7

Grade B7 is a heat-treated chromium-molybdenum alloy steel (AISI 4140/4142) quenched and tempered. It is the industry standard for high-temperature and high-pressure bolting applications in the petroleum, petrochemical, and power generation sectors. [20†L13]

Mechanical Properties:

• Tensile Strength: 125 ksi (862 MPa) min

• Yield Strength: 105 ksi (724 MPa) min

• Hardness: 35 HRC max

• Service Temperature: -40°C to +450°C

ASTM A193 B7 covers approximately 90% of standard oil and gas bolting applications, and is also widely used in pressure vessels, valves, flanges, and fittings. [20†L2-L6]

Stainless Steel Threaded Rods

• A2-70 (SS304) : General corrosion resistance, suitable for food processing, medical equipment, chemical plants, and architectural applications.

• A4-80 (SS316) : Enhanced corrosion resistance with molybdenum content, ideal for marine environments, coastal construction, saltwater exposure, and chlorine-containing settings.

Surface Finishing Options

Applications

Threaded rods are indispensable fastening components across a wide range of industries:

• Construction & Infrastructure: Concrete anchoring (chemical and mechanical anchors), structural steel connections, formwork systems, seismic retrofitting, curtain wall support systems.

• HVAC & Plumbing: Hanging ductwork, pipes, sprinkler systems, and equipment from ceilings or walls using threaded rod hangers and trapeze supports.

• Heavy Machinery & Industrial Equipment: Securing machine components, mounting industrial equipment, and creating adjustable frameworks.

• Oil & Gas / Petrochemical: High-pressure piping systems, valve and flange bolting (ASTM A193 B7), pressure vessel assembly, offshore platforms.

• Electrical & Telecom: Conduit hangers, cable tray supports, antenna mast mounting, solar panel racking systems.

• Automotive & Transportation: Engine mounts, chassis assembly, trailer hitches, rail fastening systems.

• Marine & Offshore: Boat docks, shipbuilding components, offshore platform anchoring (Stainless Steel 316).
