The DIN 975 Threaded Rod serves as the global industrial benchmark for metric series full-thread studs. Engineered for versatility and precision, these all-thread rods are continuously threaded from end to end, providing an indispensable solution for structural suspension, HVAC installations, and heavy-duty machinery assembly. Whether used for hanging pipes or creating custom-length stud bolts, the DIN 975 system ensures seamless linear load transmission and infinite adjustability.
LONGZE Fasteners delivers high-performance DIN 975 solutions integrated into a structured engineering fastening system. By adhering to strict ISO and DIN 13 thread profiles, our threaded rods guarantee total compatibility with standard metric nuts and washers. Designed for demanding environments, our product range supports large-volume infrastructure projects across Europe and Asia, bridging the gap between technical precision and commercial scalability.

Frequently Asked Questions
DIN 975 refers specifically to full-thread rods (all-thread), whereas DIN 976-1 covers stud bolts which may have partially threaded ends. While DIN 975 has been partially replaced by DIN 976-1 in official records, it remains the industry standard term for full-thread rods.
For photovoltaic (PV) brackets, we recommend Stainless Steel A2 or A4 for maximum corrosion resistance, or Hot Dip Galvanized (HDG) steel for a balance of high strength and weather protection.
Yes, they are designed to be cut to specific lengths in the field. We strongly recommend chamfering the cut ends to prevent thread damage and ensure smooth nut engagement.
DIN 975 rods are typically paired with DIN 934 Hex Nuts for fastening, DIN 125 Plain Washers for load distribution, and DIN 6334 Coupling Nuts for extending the overall rod length.
For high-tensile industrial requirements, we offer property classes 8.8, 10.9, and 12.9, providing significantly higher yield strength than standard 4.6 or 4.8 grade steel.
Yes, LONGZE Fasteners specializes in large-volume production of DIN 975 threaded rods, serving as a primary partner for infrastructure developers across Europe and Asia with consistent quality control.
