Toolholder Retention Knob Socket

Check up to five results to perform an action.

Lifetime GuaranteeSockets aid the installation and removal of Retention Knobs. By using a Socket and a Torque Wrench the ideal tightness is achieved, without rounding off the Retention Knob's corners. Sockets are designed to work when flats are up to .020 under Wrench Size Max.

Extend the life span for the Retention Knob and tool holder. Retention Knobs can be tightened uniformly with the use of a torque wrench and a socket. This gives the exact tightness that the manufacturer's specifications require.
  • Lifetime Guarantee
  • Made in the USA
  • Material made in the USA
  • Sockets have 1/2" drive
Warning & Safety Note: Open end or adjustable wrenches can slip off the Retention Knob resulting in rounding-off of corners and damage to the Knob and/or injure the Operator.

Note: Some Retention Knobs have mixed standards. Check the shoulder Diameter and Wrench Sizes Carefully when selecting a Socket to fit your requirements
