DIN 975 is a German industrial standard specifying technical requirements for fully threaded rods (also called continuous threaded studs), designed for applications requiring uniform threading along the entire length.

1. Key Features
Thread Type: Metric threads (e.g., ISO-compliant), predominantly right-hand; left-hand threads available for special orders.
Materials: Carbon steel (strength classes 4.8, 8.8), stainless steel (A2/A4), etc., balancing strength and corrosion resistance.
Surface Treatments: Zinc-plated (electro-galvanized or hot-dip), Dacromet, phosphated, etc., for diverse environmental conditions.

2. Dimensions
Diameter: Standard range M6 to M36 (larger sizes customizable).
Length: Up to 3 meters typically; longer lengths available upon request.

3. Applications
Industrial: Mechanical assemblies, equipment frameworks, pipe supports.
Construction: Steel structures, bridge anchorages, seismic reinforcement.
Automotive/Rail: Heavy-duty component rigging, rail fastening systems.

4. Advantages & Notes
Pros: Full-length threads enable flexible adjustment; compatibility with metric fasteners.
Alternatives: May overlap with ISO 4762 or EN standards; confirm project specifications.
Updates: Verify latest DIN or harmonized EN versions for compliance.

Summary: DIN 975 threaded rods offer versatility for cross-industry fastening solutions. Selection should prioritize load capacity, environmental exposure, and installation requirements.
