Heavy Duty Stainless Steel Indexing Pins And Self Locking Plungers With Coarse Thread Nuts In M6 M8 M10 M12 Sizes Plus Black Knobs For Workshop Jigs That Lock Dead Tight And Nail Positioning Every Time
✔️ Stainless steel pins come in M6 M8 M10 M12 sizes
Packed as single units per selected diameter, these heavy duty indexing pins function as reliable self locking plungers that grip workshop jigs, CNC fixtures, and assembly rigs dead secure. Built from solid stainless steel and topped with a black polymer knob, they let you engage and release position without fumbling for wrenches. You get repeatable part locking that saves bench time and cuts down setup headaches on the daily.
✅ Hand retractable black knob slides smoothly into pre drilled holes✅ Coarse thread nuts grip firmly without backing out under vibration
✅ Corrosion resistant shaft maintains linear slide unit precision
✅ Direct drop in fitment for aluminum jig plates and steel worktables
💡 What makes a spring loaded indexing pin handy for repetitive jig setups?
These components use a precision machined detent ball housed inside a hardened sleeve to catch aligned grooves and hold position rigidly.
- dialing the thread pitch to match your base plate ensures even clamping force across the contact surface
- picking stainless construction avoids galvanic reaction when mounting directly onto aluminum frames
- engaging the external lever moves the internal pin axially so operators reset fixtures without cross threading
Proper torque on the retaining nut keeps wobble out and holds dimensional accuracy through thousands of cycles.
