Heavy duty index plungers for secure bolt alignment jobs
✔️ Compatible with M6 M10 M12 bolts using durable spring pins

These heavy duty index plungers give you instant control when bolting down machinery or building custom fixtures. You slide the pin onto the threaded fastener and lock it tightly so the nut does not spin while you apply torque. The spring loaded tip stays locked firmly inside drilled holes for repeatable positioning on steel plates. Grab yours whenever you face stubborn hardware that refuses to stay aligned during welding or machining.

✅ Matches M6 M10 and M12 hex head sizes and set screws
✅ Spring loaded design maintains steady torque during installs
✅ Heavy steel construction grips hard materials without slipping
✅ Quick release mechanism saves setup time for large projects

💡 What makes spring loaded indexing tools handy for securing threaded fasteners on metal frames? The pinned mechanism gives you absolute control over bolt placement while you tighten high torque joints.

• Locking action holds the shaft steady so your wrench only turns the nut rather than spinning the bolt
• Durable spring core absorbs shock loads and keeps alignment precise through multiple cycles
• Direct thread engagement prevents stripped holes and speeds up heavy fixture buildup
