U-bolt | M10-M12 | A2 | DIN 3570-A
Stainless steel U-bolt is intended for the mounting and fastening of pipes in industrial and outdoor installations. The product complies with DIN 3570-A and is used where stable and corrosion-resistant pipe mounting is required. It is suitable for professional installations where long service life and consistent performance are crucial.
NOTE! The design is adapted for pipe dimensions according to NPS (Nominal Pipe Size), where the size is specified in inches but does not correspond to the actual outer diameter of the pipe. U-bolts are therefore specified by nominal pipe dimension and not by the internal width of the bolt. See the size chart for exact measurements.
APPLICATION AREA
The product is used in plumbing, the process industry, and technical piping systems. It is intended for applications where secure pipe fixation is required and where the material choice provides the necessary protection against corrosion and mechanical stress.

FREQUENTLY ASKED QUESTIONS (FAQ)
What is a DIN 3570-A U-bolt used for?
The U-bolt is used for fastening pipes against walls, profiles, beams, or other structural surfaces in pipe installations and industrial applications.
What does NPS mean for pipe dimensions?
NPS (Nominal Pipe Size) is a standardized inch-based system for pipe dimensions where the designation does not correspond to the actual outer diameter of the pipe.
Why does the inch size not match the bolt's measurement in millimeters?
Pipe dimensions according to NPS are based on nominal size. The U-bolt is therefore manufactured to fit the pipe's actual outer diameter, including the necessary mounting clearance.
What does material grade A2 mean?
A2 is a stainless steel with good corrosion resistance for outdoor environments and normal industrial settings.
Can the U-bolt be used in marine environments?
No, A2 (AISI 304) is not acid-resistant and is not recommended for marine environments or saltwater. For such environments, an acid-resistant A4 (AISI 316) U-bolt should be chosen.
