Pack Of Two M12 Retractable Plunger Locking Pins
✔️ M12 Retract Latch Pin With Mounting Nut And Hex Shaft

A pair of heavy duty retractable index pins gives you solid mechanical stops for welding fixtures, jigs, and fabrication benches. The telescopic bodies slide smooth inside drilled holes so operators can swap workpieces fast without struggling with stubborn clamps. Factory floors and shipyards rely on these spring loaded latches to keep assemblies tight through vibration and heavy handling. You simply thread the included nuts into tapped holes, push the handle down to release the shaft, and flip the lever to lock it flat against the plate.

💡 How do retractable indexing plunger pins boost rigidity on custom jig frames?
The telescopic design locks directly into tapped holes to stop workpiece shift during heavy cuts.
1. The hardened steel sleeve grips guide bores to kill lateral movement and chatter.
2. Built-in compression springs keep the latch snugged tight even when machines vibrate hard.
3. Technicians bypass traditional toggle clamps and swap fixtures in seconds without losing positional accuracy.
