The plunger body threads into a tapped hole using a 1\/2-13 thread and delivers an initial end force of 0.5 pounds and a final end force of 2 pounds, making it suitable for repeatable, controlled detent action. The plunger diameter is 0.31 inches with a projection of 0.4 inches. Total body length is 1.5 inches, with a thread length of 0.85 inches and a length under head of 1 inch. Machinists, toolmakers, and maintenance technicians install this type of plunger in fixtures, jigs, and production equipment.\u003c\/p\u003e\u003cp\u003eThe FRSN500P is applied in mechanical fixturing, tooling plates, and machine assemblies where a spring-loaded detent or stop point is required. Its non-locking plunger design allows free retraction without a secondary release mechanism, making it practical for high-cycle indexing applications. The L-handle configuration allows hand adjustment and installation without additional tooling in accessible locations. This plunger is appropriate for use in both production and maintenance environments across general manufacturing and precision assembly operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNon-locking plunger for free retraction in detent and indexing applications\u003c\/li\u003e\n\u003cli\u003e1\/2-13 thread for installation in standard tapped holes\u003c\/li\u003e\n\u003cli\u003eEnd force range of 0.5 pounds initial to 2 pounds final for controlled spring resistance\u003c\/li\u003e\n\u003cli\u003eL-style steel handle allows hand tightening and removal in accessible locations\u003c\/li\u003e\n\u003cli\u003e0.4 inch plunger projection provides positive detent engagement\u003c\/li\u003e\n\u003cli\u003eCompact 1.5 inch body length suits space-constrained fixture designs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-install spring plunger for mechanical fixtures, jigs, and tooling assemblies requiring a 1\/2-13 threaded non-locking plunger.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by toolmakers, machinists, or maintenance technicians. Thread the plunger body into a pre-tapped 1\/2-13 hole and tighten to the desired position using the L handle or an appropriate hex wrench on the 0.5 inch hex. Ensure the mating bore or detent feature is aligned with the plunger projection before final seating. De-energize or lock out any associated equipment before installing or servicing plungers in active machinery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.85 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Diameter\u003c\/strong\u003e: 0.31 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Type\u003c\/strong\u003e: Non-Locking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Style\u003c\/strong\u003e: L Handle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Diameter\u003c\/strong\u003e: 0.19 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Between Head and Thread\u003c\/strong\u003e: 0.15 inches\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: FRSN500P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51997010034994,"sku":"FRSN500P","price":30.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a52221cc6604f8c5ecdcac5f1fb96989_e08921a8-3ca6-4a6f-b3ab-2e67b1e0d364.jpg?v=1789993772","url":"https:\/\/voomisupply.com\/products\/vlier-frsn500p-spring-plunger-1-2-13-non-locking-l-handle","provider":"Voomi Supply","version":"1.0","type":"link"}
