[JM Performance Products JM Performance Products, Inc. is the leading manufacturer of retention knobs, High Torque retention knobs, Spindle cleaners, and drawbar gages.
Originally founded under the name J&M Machine, Inc. we recently changed names as our focus changed. Established in 1966, with only a handful of machines and a family's desire to be more than the stereotypical job shop, J&M Machine was founded. Since that time, JM Performance Products has firmly established itself as a model shop leader for manufacturing development, and quality control of precision turned parts.
Over the years, we have added the most up-to-date machines and equipment to attain a complete CNC primary department, and are also looking to convert our secondary department to CNC's. Our sophisticated Quality Control Department ensures that absolute top quality and performance is accomplished at all times.
