Product Overview of Ball Plungers
·Ball Plungers, also known as ball point set screws, ball screws, positioning balls, touch balls, steel ball tightening spring screws, etc., can be used for temporary positioning and index adjustment of workpieces, relying on the spring to push out the front ball through a fixed stroke.
Product Feature of Ball Plungers
·Made entirely of stainless steel, with no painting or coloring, they are suitable for more equipment with higher surface requirements.
·As there is no wrench slot on the tip, please use the Ball Plungers with an Allen wrench.
·The Ball Plungers has a simple structure: the front ball is pushed out through a fixed stroke by the internal spring and it can be released by pressing in the ball against the elastic force.
·Flexible installation: Suitable for linear motion and rotary motion mechanisms with positioning requirements, the plunger can be installed using general threads, which facilitates assembly and disassembly.
·Suitable for fixture indexing, positioning, stop limit and other occasions.
·The stroke can be fine-tuned by screwing-in depth of the screw.

Frequently asked question (FAQ)
- Question: What role does a ball plunger play?
- Answer: It specifies the stroke of the front ball and can be used for temporary positioning and indexing of workpieces.
- Question: What is the anti-loosening treatment of a ball plunger?
- Answer: It refers to fixation using anaerobic adhesives filled in microcapsules. A ball plunger will fail once it becomes loosened, so it is necessary to use anaerobic adhesives for threads. An ideal anti-loosening effect will be achieved when placed at a temperature above 25℃ for 72 hours.
- Question: What is the meaning of max load and min load?
- Answer: It refers to the load of the spring in the product. The min load represents the initial load value, and the max load represents the load value at the maximum press-in limit.
- Question: What is the difference between a ball plunger and a spring plunger?
- Answer: A ball plunger is headed with a steel ball and its stroke is the displacement of the ball. A spring plunger has a pin-shaped front section and the displacement stroke of the pin is used for such purposes as temporary positioning and indexing of workpieces.
