Product Info


  • Spline fasteners help tighten high strength bolts to high torque loads
  • They help lower the force required to turn standard fasteners by allowing the torque load to be moved away from the corners, helping prevent fastener rounding
  • They also turn fasteners with damaged corners
  • Spline helps reduce foreign object debris by having a precise fit between the fastening tool and its fastener
  • Full polish finish provides corrosion resistance and an easy-to-clean surface
  • Anti-slip design (ASD) open end
