Our imperial adjustment knobs allow for quick screw adjustment without requiring a hex key. The outer diameter is knurled for increased grip while turning, and the threaded inner diameter allows for easy placement and/or removal from a screw. Imperial knobs are made of 303 stainless steel.

Our imperial adjustment knobs can be supplied upon request with specified:
  • Optional materials
  • Lengths and diameters
  • ID threads
Our highly developed proprietary machining and custom modified machines enable us to produce our 80 TPI to 254 TPI fine and ultra-fine knobs to standards that exceed those of the industry.

Note: Kozak Micro cannot guarantee that our imperial knobs will be compatible with screws sold by other manufacturers.
