Threaded rods DIN 976 in stainless steel A2 and A4, M3-M24
This category contains 43 stainless steel threaded rods to DIN 976 with full-length metric thread. They are used for mounting photovoltaic structures and brackets, and for general construction and installation work. The range covers A2 and A4 steel, thread sizes M3 to M24 and lengths of 1000 and 2000 mm. It is intended for installers and builders.
What you will find in this category
- A2 stainless steel 1.4301 rods, M8 to M16, 1000 mm long, for photovoltaic panels and mounting brackets.
- A2-70 stainless steel rods, M3 to M24, 1000 and 2000 mm long, with tensile strength 700 N/mm² and corrosion resistance class CRC II.
- A4-70 stainless steel rods (AISI 316), M3 to M24, 1000 and 2000 mm long, with tensile strength 700 N/mm² and corrosion resistance class CRC III.
How to choose
- Material: A2-70 (CRC II) suits general outdoor and construction use. A4-70 (CRC III) contains 2-3% molybdenum for corrosive environments.
- Thread size: choose from M3 to M24 to match the load and the fixing point. Check that the size matches your nuts and washers.
- Length: rods come in 1000 mm and 2000 mm. Pick the longer length if you need to cut several pieces.
- Strength: A2-70 and A4-70 rods have a tensile strength of 700 N/mm², so the choice is mainly about corrosion resistance.
- Compatibility: the M16 A4-70 rod is listed as compatible with DIN 934 nuts and DIN 125 washers.
Typical applications
These rods are used to mount solar panels on roofs and to secure mounting brackets to surfaces. They also serve in steel structures, building installations and ventilation installations. A4-70 versions are listed for structures exposed to moisture, chlorides and other aggressive environments.
Frequently asked questions
What is the difference between A2-70 and A4-70 rods?
Both have a tensile strength of 700 N/mm². A2-70 has corrosion resistance class CRC II. A4-70 is AISI 316 steel with 2-3% molybdenum and class CRC III, for aggressive environments.
Is the thread cut along the whole rod?
Yes. The A2-70 and A4-70 rods have a metric thread along their entire length, so they can be cut and used at any point.
Which lengths are available?
The rods are available in 1000 mm and 2000 mm lengths. Thread sizes range from M3 to M24, depending on material and length.
