A4-70 Stainless Steel Threaded Rod
A4-70 Stainless Steel Threaded Rod is a fully threaded fastening component manufactured from A4 stainless steel, which is equivalent to 316 stainless steel. The threaded rod is produced according to DIN 975 or DIN 976 dimensional requirements, providing standardized thread dimensions and reliable compatibility with stainless steel nuts and other fastening components.
With a minimum tensile strength of 700 MPa according to ISO 3506 requirements, A4-70 Threaded Rod combines excellent corrosion resistance with enhanced mechanical performance. It is suitable for applications requiring long service life and reliable fastening in marine, chemical, outdoor, and industrial environments. Available in various diameters, lengths, and thread configurations, A4-70 Stainless Steel Threaded Rod can be supplied for standard applications as well as customized projects requiring specific dimensions or surface conditions.
Specification of A4-70 Threaded Rod:
A4-70 Stainless Steel Threaded Rod is manufactured according to ISO 3506 requirements for stainless steel fasteners and DIN 975 / DIN 976 dimensional standards for fully threaded rods. The material grade is A4 stainless steel (SS316 equivalent), with a chemical composition mainly consisting of chromium (Cr), nickel (Ni), and molybdenum (Mo). The A4-70 property class requires a minimum tensile strength of 700 MPa and is suitable for applications requiring reliable mechanical performance and corrosion resistance.
The threaded rods are available in metric sizes from M3 to M48 or according to customer specifications, with coarse thread and fine thread options available. Standard lengths include 1000 mm, 2000 mm, and 3000 mm, while customized lengths can be produced according to project requirements. Thread accuracy, diameter tolerance, and straightness are controlled during the manufacturing process to ensure proper assembly with matching nuts and components.
Surface conditions include cleaned finish and passivation treatment according to customer requirements. Passivated A4-70 Stainless Steel Threaded Rod provides a clean surface condition and helps maintain the corrosion resistance of the stainless steel material. Inspection documents such as material certificates, dimensional inspection reports, and mechanical test reports can be provided when required.

Applications of A4-70 Stainless Steel Threaded Rod:
A4-70 Stainless Steel Threaded Rod is widely used in applications requiring continuous threaded connections, corrosion resistance, and reliable mechanical performance. Unlike standard bolts, threaded rods provide flexible cutting and installation options, allowing users to create customized fastening lengths for different assembly, support, and anchoring requirements.
These stainless steel threaded rods are commonly used in marine equipment, chemical processing facilities, water treatment systems, construction projects, industrial machinery, electrical installations, and outdoor structures. Their resistance to moisture, salt spray, and corrosive environments makes them suitable for applications where long service life and reduced maintenance are important.
Typical applications include threaded connections for pipe supports, equipment mounting, suspended systems, structural supports, anchor assemblies, and custom fastening solutions. With standard metric dimensions according to DIN 975/DIN 976 and A4-70 stainless steel performance according to ISO 3506, these threaded rods provide a reliable solution for OEM manufacturers, contractors, and industrial users.
Quality Control:
Quality control is implemented throughout the manufacturing process of A4-70 Stainless Steel Threaded Rod to ensure consistent dimensions, thread accuracy, and reliable mechanical performance. Before production, A4 stainless steel raw materials are inspected and verified to ensure compliance with ISO 3506 material and performance requirements.
During manufacturing, key processes including cutting, thread rolling, straightness control, and surface treatment are carefully monitored. Dimensional inspections are performed on critical parameters such as rod diameter, thread pitch, length, and surface condition to ensure compatibility with matching nuts and fastening components.
With experienced production teams and reliable manufacturing resources, we are capable of supplying both standard and customized A4-70 Stainless Steel Threaded Rod orders. Before shipment, finished products are inspected according to customer requirements, and documents such as material certificates, inspection reports, and mechanical test reports can be provided to support industrial and engineering projects.
