Frequently asked question (FAQ)

Question: Can the knob plunger withstand radial force?
Answer: It is not recommended to bear radial cutting force, as it is prone to product damage and fracture, and generally it can only bear axial force.
Question: What role does a ball plunger play?
Answer: It is a mechanical element part that can easily and quickly locate and fix the workpiece by operating the knob or the handle to pull out or insert the pin. Early knob plungers were mainly used for parts used in the angular positioning of indexing devices. In recent years, knob plunger has been more widely used, and become an indispensable mechanical element part of equipment and devices.
Question: What are the characteristics of fine thread type compared to coarse thread type?
Answer: Fine thread type is suitable for fine-tuning the ejection amount of the pin. More precise positioning is more possible compared to coarse thread type.
Question: What is the difference between reset type and self-locking type knob plungers?
Answer: The self-locking type can lock the front end by turning 90° after pulling out the knob, while keeping the pulled state and turning 90° to release the lock.
