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. Plain Point Set Screws are used against hardened shafts, in zinc, die castings and other soft materials where high tightening torques are impractical.

• Balanced heat treatment for uniform hardness, assuring maximum strength without brittleness
• 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.
