The plunger features a 5\/8-11 thread with a 1-1\/2 inch thread length and a standard-length steel body. The nose projects 5\/16 inch and measures between 0.308 and 0.310 inches in diameter. Initial end force is 3.5 pounds; final end force is 10.5 pounds. A locking element is integrated into the body to prevent the plunger from backing out under vibration. Machinists, tool and die technicians, and mechanical assembly professionals install these in jigs, fixtures, and machine tool components.\u003c\/p\u003e\n\u003cp\u003eThe S63N suits applications where a spring-loaded plunger must engage a detent or locating hole to hold a workpiece or moving assembly in a repeatable position. The locking element feature makes it suitable for environments with continuous vibration or cyclic loading where a non-locking plunger would walk out over time. Typical installations include fixture plates, indexing tables, sliding carriages, and tooling bodies in both light manufacturing and precision machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 thread size with 1-1\/2 inch thread length for secure mounting in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eSteel nose and steel body for durability in industrial service\u003c\/li\u003e\n  \u003cli\u003e3.5 pound initial end force and 10.5 pound final end force for consistent detent engagement\u003c\/li\u003e\n  \u003cli\u003eIntegrated locking element prevents unintended backing out under vibration\u003c\/li\u003e\n  \u003cli\u003ePlunger diameter range of 0.308 to 0.310 inches for close-tolerance detent engagement\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch plunger projection for reliable engagement depth in standard detent applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit threaded spring plunger for tapped holes requiring a 5\/8-11 thread.

Ensure the mating hole or cavity is free of chips and debris before installation. Torque the plunger to the tool or fixture manufacturer's specification for this thread class. Disengage any mechanical load or moving assembly before servicing the plunger.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Plunger Diameter\u003c\/strong\u003e: 0.308 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.310 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 3.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 10.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: S63N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51972028989746,"sku":"S63N","price":25.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/66a4e7a93a680a485853722e191faaf0_1fdf63e7-524f-4015-9977-772b999e112e.jpg?v=1789961439","url":"https:\/\/voomisupply.com\/products\/vlier-s63n-threaded-spring-plunger-5-8-11-steel-body","provider":"Voomi Supply","version":"1.0","type":"link"}
