Heavy Duty Self Locking Knob Plunger With Slick Spring Slide And Roughneck Grip For Precision Jig Positioning And Shop Equipment Fine Thread Indexing Lock Pin M10 M16 M20

Heavy Duty Stainless Steel Locking Pin For Shop Jigs
✔️ M16 stainless self locking plunger with fast spring return action

You will mount this steel index pin to square up jigs, clamp stop blocks, or set up quick fixtures on the bench. Pull the grip outward, spin it back ninety degrees, and let the internal spring seat the stem right where you need it. The knurled face gives you plenty of torque when your fingers get tired or your gloves slip around the handle. You can quickly release the pin during layout work and lock it down for actual machining. Your tooling stays crisp because the hardened shaft glides smoothly without biting into soft metal.

✅ Fine pitch threading accepts standard M16 bolts for secure panel mounting
✅ Precise stainless build measures 77mm/3.03inch overall length for stable reach
✅ Return spring mechanism pushes the stem out automatically after each cycle
✅ Knurled outer sleeve gives you a solid grip even with light glove friction
