JM Performance Products offers high torque retention knobs in high strength steel.  Manufactured from 9310 steel, JM’s high torque-high strength knobs are 40 percent stronger than standard knobs, the company says. High torque retention knobs have a design that prevents toolholder distortion. They are longer than a traditional retention knob, but share the same head dimensions. The additional length also increases durability of the high torque knob; a standard knob has less shank elasticity and will fatigue faster. The extra length of the knob is added to the shank of the knob below the flange. This relief, along with a precision pilot and controlled threads, allows for the stress to be distributed into a deeper cross-section of the toolholder, where it has more resistance. High torque retention knobs work in any new or used toolholder made to industry specifications.
