Frequently Asked Questions
Q: What thread size do these stainless steel indexing plungers use?
A: These pull ring indexing plungers are sized at M2×3, with an overall length of 37 mm (1.46 inches). This compact sizing makes them well-suited for lighter-duty assembly fixtures, small jigs, and precision positioning applications.
Q: What does "non lock-out type" mean for a knob plunger?
A: A non lock-out type plunger means the spring-loaded pin will automatically return to its extended (engaged) position when released. You simply pull the ring to retract the pin, reposition your component, and let go — the spring snaps the pin back into place without any additional locking step required.
Q: Are these indexing plungers suitable for industrial machinery use?
A: Yes. The stainless steel construction provides excellent corrosion resistance and structural rigidity, making these knob plungers suitable for a broad range of settings including industrial machinery, conveyor systems, workholding fixtures, and furniture assembly where repeatable, precise positioning is needed.
Q: How many plungers are included in each set?
A: Each order includes a set of 4 stainless steel pull ring indexing knob plungers, giving you spares on hand or the ability to equip multiple positions on the same assembly.
