Features
Unbrako Socket Head Cap Screws are suitable for all high tensile applications. Compared to other threaded fasteners, Unbrako's Socket Head Cap Screws have higher tensile strength, tighter tolerances and reduced fatigue resistance for greater performance and savings. Deep accurate non-slip sockets provide maximum key engagement for full tightening without marring the surrounding surface.
- Total Traceability: Patented E-CODE™ head marking system allows tracing of test records for each production lot.
- Specially designed elliptical fillet doubles the fatigue life at critical head-shank juncture.
- Increased bearing area of head for greater load carrying capability and precision forged for symmetrical grain flow providing greater strength.
