This retractable spring plunger acts as a reliable locking pin for jig setups, workholding fixtures, and custom tooling stations. You slide the collar back to extend the stainless steel tip, lock the location, then pull to retract when you need to swap parts fast. Shop crews love these for CNC machining tables and automated assembly lines where consistent positioning matters. The slim profile slips into tight clearances without stealing valuable bench real estate. Reliable operation depends on proper tap drilling, which keeps the fine pitch engaged securely.

✅ Thread length runs 20mm alongside 0.79 inches for deep seating ✅ Pin diameter measures 6mm next to 0.24 inches for smooth indexing ✅ Stainless build resists rust while handling heavy clamping loads ✅ Thin threading lets mechanics dial in exact setup positions
