Five Piece Zinc Coated Carbon Steel Spring Loaded Plunger Pins, Tough As Nails Retractable Indexing Tools With L Grip Handle, Heavy Duty Locking Bolts For Four Inch Aluminum Extrusion And Crossbeams
✔️ 5 Pack M12 x 2.0 Zinc Steel Indexing Mounting Bolts
These spring loaded plunger pins function as retractable indexing tools built to clamp workpieces solid and keep jigs aligned on metal frames. You will usually spot them running on fabrication benches, woodworking stations, and industrial assembly rigs where operators need fast one handed tweaks without stepping away from the task.
✅ Material and Finish: Built from carbon steel with a zinc plated coating to fight off rust during daily shop abuse.✅ One Hand Control: An L shaped grip pairs with a strong internal spring so you can drop and release the shaft fast.

✅ Bulk Packaging: You get a straightforward 5 pack to cover bigger builds and spare part needs on the fly.
💡 What is a spring loaded plunger pin used for? These retractable indexing bolts are seriously handy for locking workpieces in place during welding, machining, or frame assembly tasks. - Anchor aluminum extrusion beams and crossbar brackets without requiring secondary drill operations or tap wrenches. - Maintain repeatable axial positioning tolerance across custom jig plates and modular factory tooling setups. - Deploy consistent compression forces through hardened internal springs to prevent accidental shaft retraction under load. - Streamline bench adjustments for heavy duty fabrication cells and quick-change workstation configurations.
