The only thing standing between a job well done and catastrophic failure is the retention knob. MegaFORCE Retention Knobs are designed to deliver superior performance and enhanced safety for the critical connection between your machine spindle and the tool holder.Retention Knobs are subjected to extreme pulling forces of up to 5,000 ft. lbs. Over time, this stress exploits weaknesses in the retention knob and can lead to breakage. MegaFORCE Retention Knobs have been designed and manufactured to increase the strength and durability of this critical connection.
The longer overall length engages threads deeper in the tool holder, reducing taper swelling and maximizing taper/spindle contact for the most rigid connection. MegaFORCE also features a redesigned, blended radii for improved overall strength, making MegaFORCE the strongest high-torque retention knob in the market.
