- Advantages built into every detail
- 1
- Higher Tensile Strength
- Unbrako tensile specifications are 10,000 psi higher than industry standard - while maintaining the core hardness range.
- 2
- E-CODE™ Head Marking
- The ultimate in fastener traceability - from its original manufacturing lot, raw material chemistry to performance test results.
- 3
- Compound Fillet Radius
- This design change alone is responsible for doubling fatigue life at critical head-shank juncture.
- 4
- Radiused Root Runout (3R)
- Provides a smooth form that distributes stress and increases fatigue life of thread run-out as much as 300% in certain sizes.
- 5
- Wide Root Thread Form
- An Unbrako development that doubles the fatigue life compared to flat root thread forms.
- 6
- Etching for Thread Laps
- The only method to detect thread laps is that random samples of rolled threads are etched in heated acid, and then examined under a stereo microscope.
- 7
- Forged Heads
- The flow lines of the material are continuous, resulting in increased strength, better installation ability, and a longer product life.
- 8
- Rolled Threads
- Roll threading compresses the material’s grain flow and enhances fatigue resistance.
- The Largest Industrial Fasteners Manufacturer in India and the proud worldwide owner of the brand Unbrako,
