The steel body accepts a 3\/8-16 thread and measures 0.625 inches in body length. The steel nose plunger delivers an initial end force of 4.5 pounds and a final end force of 18.5 pounds, with a maximum plunger diameter of 0.186 inches and a projection of 0.11 inches. A built-in locking element secures the plunger in position once installed. This component is typically installed by machinists, toolmakers, and mechanical assembly technicians working with fixtures, jigs, and precision equipment.\u003c\/p\u003e\u003cp\u003eThe M58N fits applications where high end force is needed in tight or restricted spaces. Its stubby profile makes it suitable for use in fixture plates, tooling bodies, and mechanical assemblies where standard-length plungers would not fit. The 3\/8-16 thread allows installation into standard tapped holes using common hand tools. This plunger is appropriate for both production line tooling and custom fabrication setups where repeatable, controlled detent or positioning force is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStubby plunger length type suited for restricted-space installations\u003c\/li\u003e\n\u003cli\u003e3\/8-16 thread with 0.625 inches thread length for standard tapped hole compatibility\u003c\/li\u003e\n\u003cli\u003eInitial end force of 4.5 pounds and final end force of 18.5 pounds for high-force positioning\u003c\/li\u003e\n\u003cli\u003eSteel body and steel nose for durability in industrial environments\u003c\/li\u003e\n\u003cli\u003eBuilt-in locking element prevents loosening under vibration or repeated cycling\u003c\/li\u003e\n\u003cli\u003eMaximum plunger diameter of 0.186 inches with 0.11 inches projection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit threaded spring plunger for fixtures, jigs, and mechanical assemblies requiring a 3\/8-16 tapped hole and high end force in restricted space.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a properly tapped 3\/8-16 hole in the receiving component. Power down or de-energize any associated equipment before servicing mechanical assemblies containing this plunger. Use the appropriate thread engagement and torque the plunger body with a hex key or wrench to the assembly specification  -  do not overtighten, as this can damage the locking element or bore. Confirm plunger projection and end force match the application requirement before finalizing the installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.11 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.186 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 4.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 18.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Stubby\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: High End Force, Restricted Space\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VLIER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: M58N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":52069656559922,"sku":"M58N","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b9a26d4cb0cc73d2c3571edf66303cd8.jpg?v=1790047929","url":"https:\/\/voomisupply.com\/products\/vlier-m58n-threaded-spring-plunger-3-8-16-steel-locking","provider":"Voomi Supply","version":"1.0","type":"link"}
