Heavy Duty Spring Plungers With Quick Lock Nuts For Workshop Use
✔️ 304 Stainless Steel Build With Knurled Handle For Secure Grip Control

You grab a handy set of heavy duty spring plungers designed to lock panels, jigs, and machine parts in place during setup or repair. This kit delivers two plunge bodies plus matching M6 hex nuts so you can mount them right off the shelf. The rotating sleeve lets you pull the pin back for instant release or snap it forward for a solid hold. You will appreciate how fast these work on welding racks, 3D printer frames, and prototype rigs that need steady positioning day after day.

✅ Comes with two spring plunger bodies paired with tight fitting M6 threaded nuts
✅ Knurled outer grip stops slippage even when your hands are greasy or gloved
✅ Simple turn action shifts the retaining pin from locked to released position fast

💡 What keeps a retaining pin steady under heavy vibration on industrial equipment?
A dedicated spring loaded plunger transfers shock loads away from fasteners by pressing directly against a matching hole face.
- Hardened stainless steel barrel prevents bending when bolts tighten to spec torque values
- Strong internal coil compression holds the pin perfectly flush until you rotate the body shell
- Metric M6 threading aligns cleanly with standard fixture brackets for repeatable jig accuracy
