- D (Thread Diameter): M10 – Standard ISO Metric thread, ensuring compatibility with standard M10 nuts.
- W (Inside Width C-C): 42.0 mm – This dimension is designed to perfectly fit DN32 (1 1/4″) pipes with an outer diameter of approximately 32mm-42mm.
- H (Inside Height): 85.0 mm – The total internal clearance from the top of the bend to the base of the fastener.
- T (Thread Length): 35.0 mm – Ample threading provided to accommodate mounting plates, washers, and double-nutting if required.
- R (Inside Radius): 21.0 mm – Precision bending radius to ensure a snug fit around cylindrical piping.
- d (Wire Diameter): 9.0 mm – The thickness of the bolt body before threading, providing structural rigidity.
- P (Thread Pitch): 1.5 mm – Standard coarse pitch for secure fastening and vibration resistance.
- C (Center-to-Center Distance): 51.0 mm – Distance between the center points of the two threaded legs, critical for pre-drilling mounting holes in plates or beams.
