Features

Unbrako Socket Set Screws can withstand tightening torques as much as 40% higher than other set screws, giving you extra holding power and additional safety and reliability. Since holding power is proportional to seated torque, Unbrako Socket Set Screws are the most effective by producing a strong clamping action which resists the relative motion between the assembled parts. Unbrako Knurled Cup Point Set Screws offer exclusive counterclockwise locking knurles that resist screw loosening or most severe vibration.

  • Counterbored knurled cup self-locking point provides greater vibrational holding power, even in poorly tapped holes.
  • Rounded corners resist cracking and allow set screws to withstand high tightening torques.
  • Key fits deeply into the socket to provide extra wrenching area for secure tightening without reaming the socket or rounding off corners of the key.
