The plunger features an M5 x 0.8 thread with a 14.5 mm thread length and a 2.36 mm maximum plunger diameter. A 3 mm projection provides reliable engagement force with an initial end force of 0.14 kg and a final end force of 1.36 kg. The steel body offers durability in demanding shop environments, and the Delrin nose reduces wear on mating surfaces. A locking element is included to secure the plunger against rotation or backing out once installed.\u003c\/p\u003e\n\u003cp\u003eThis spring plunger is suited for use in tooling plates, workholding fixtures, machine tool components, and industrial assemblies where repeatable positioning or controlled detent action is required. It is installed by machinists, toolmakers, and fixture builders in both light manufacturing and precision machining environments. The compact M5 thread size makes it appropriate for smaller fixtures or applications where space is limited.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM5 x 0.8 thread with 14.5 mm thread length for standard metric tap compatibility\u003c\/li\u003e\n  \u003cli\u003eShort plunger body at 14.5 mm overall length suits compact fixture designs\u003c\/li\u003e\n  \u003cli\u003e2.36 mm maximum plunger diameter with 3 mm nose projection\u003c\/li\u003e\n  \u003cli\u003eInitial end force of 0.14 kg and final end force of 1.36 kg for light detent engagement\u003c\/li\u003e\n  \u003cli\u003eDelrin nose material minimizes wear on contact surfaces\u003c\/li\u003e\n  \u003cli\u003eLocking element prevents loosening under vibration or repeated cycling\u003c\/li\u003e\n  \u003cli\u003eBlack finish steel body resists corrosion in typical shop conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct installation component for metric-threaded tooling fixtures and assemblies requiring an M5 x 0.8 short spring plunger with a locking element.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using standard metric hand tools into a properly tapped M5 x 0.8 through or blind hole.
