Threaded at 1\/2-13, it delivers an initial end force of 1 pound rising to a final end force of 5 pounds, giving technicians predictable spring resistance across the plunger stroke. The steel construction provides durability in demanding environments. With a body length of 2.11 inches and a plunger diameter of 0.31 inches, the FR500 fits standard plunger-threaded bores and installs without special tooling. The locking L handle allows the plunger to be retracted and locked in the withdrawn position, simplifying loading and alignment tasks.\u003c\/p\u003e\u003cp\u003eThe FR500 is suited for use in jigs, fixtures, machine tool components, and production equipment where repeatable positive stops or detent positioning are required. It is appropriate for both light-duty and moderate-force indexing tasks in manufacturing and assembly environments. Maintenance technicians and machine builders working with threaded plunger assemblies will find this a direct-fit replacement or upgrade for existing 1\/2-13 spring plunger locations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLocking L handle retracts and holds the plunger in the withdrawn position for tool-free loading\u003c\/li\u003e\n\u003cli\u003e1\/2-13 thread size for compatibility with standard threaded plunger bores\u003c\/li\u003e\n\u003cli\u003eInitial end force of 1 pound rising to final end force of 5 pounds for consistent indexing resistance\u003c\/li\u003e\n\u003cli\u003ePlunger projection of 0.75 inches provides adequate engagement depth for most detent applications\u003c\/li\u003e\n\u003cli\u003eSteel handle and body construction for long service life in industrial environments\u003c\/li\u003e\n\u003cli\u003eThread length of 1.1 inches and hex size of 0.5 inches allow for secure installation and adjustment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct installation component for machinery, fixtures, and assemblies using 1\/2-13 threaded spring plunger bores.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of spring plungers is typically performed by maintenance technicians or machine builders using standard hex wrenches. Ensure the mating bore is clean and properly tapped to 1\/2-13 before threading in the plunger. Avoid over-torquing the body, which can distort the thread or affect plunger travel. Verify plunger projection and spring force requirements match the application before final installation.\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: 1.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 2.11 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1.25 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: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Length\u003c\/strong\u003e: 2.11 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Length\u003c\/strong\u003e: 0.93 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\u003eHead Height\u003c\/strong\u003e: 0.86 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Between Head and Thread\u003c\/strong\u003e: 0.15 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Type\u003c\/strong\u003e: Locking\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: FR500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51972431118642,"sku":"FR500","price":29.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c416ada21b53c6a74b828e93ac551d8d.jpg?v=1789968666","url":"https:\/\/voomisupply.com\/products\/vlier-fr500-locking-l-handle-spring-plunger-1-2-13","provider":"Voomi Supply","version":"1.0","type":"link"}
