Hexagonal tube
Key Design Features:
1. Optimized Hexagonal Geometry
Superior Torsional Rigidity – Hexagonal profile provides 25-35% greater resistance to twisting compared to round tubes of equivalent weight
Six-Point Wrenching Surfaces – Precision-machined flat faces enable secure tool engagement and eliminate slippage during installation or maintenance
Even Load Distribution – 120° angular spacing ensures uniform stress distribution across all six vertices under dynamic loading
Self-Locking Anti-Rotation – Flat surfaces prevent relative rotation without additional keys, pins, or splines in mating components
2. Precision Manufacturing Process
CNC Cold-Drawing or Extrusion Technology – Automated forming ensures consistent across-flat dimensions (±0.05mm) and precise angular tolerances (±0.3°)
High-Strength Materials – Manufactured from ST52, 42CrMo, 20CrMnTi alloy steel, or 6061-T6/6063-T5 aluminum alloys
Seamless or Welded Construction – Options include DOM seamless steel tubing, ERW welded construction, or seamless extruded aluminum with complete structural integrity
Surface Finish Options – Available in cold-drawn finish, precision-ground, phosphated, black oxide, anodized, or polished surfaces per application requirements
3. Superior Mechanical Properties
Wall Thickness Range – 2.0mm to 12.0mm customizable to torque and structural requirements
High Torque Capacity – Optimized hex geometry enables torque transmission efficiency up to 95% with minimal backlash
Excellent Bending Resistance – Six distinct moment of inertia axes provide uniform strength in all radial directions
Operating Temperature Range – -50°C to +250°C for alloy steel, -40°C to +150°C for aluminum variants
4. Application-Specific Engineering
Driveline and PTO Components – Ideal for power take-off shafts, drive couplings, and torque transmission assemblies
Hydraulic Cylinder Rods – Precision hex profile for anti-rotation piston rods and cylinder barrels
Machine Tool Spindles – High-precision hex tubes for collet systems, tool holders, and spindle housings
Construction Equipment – Heavy-duty torque tubes for excavators, loaders, and drilling rigs
Agricultural Machinery – Robust hex shafts for tillage equipment, harvesters, and tractor implements
5. Versatile Configuration Options
Standard Hex Profile – Classic six-sided geometry with sharp or chamfered edges (0.5mm-2mm)
Tapered Hex Sections – Gradual dimensional changes along length for self-centering or progressive fit applications
Combination Designs – Hex profile integrated with round, square, or splined end sections for hybrid mechanical systems
Internal Hex Profile – Precision internal hex for specialty tooling interfaces or torque tube applications
End Treatment Options – Precision-machined faces, drilled mounting holes, welded flanges, or threaded transitions available
