The plunger body and nose are both steel construction, offering durability in industrial and trade environments. It uses a 5\/16-18 thread with a 1 inch thread length, a plunger projection of 3\/16 inch, and a plunger diameter ranging from 0.133 to 0.135 inches. Initial end force is 3 pounds and final end force is 15 pounds, making it suitable for light detent and positioning tasks. Machinists, millwrights, and mechanical assembly technicians are the typical installers of this component.\u003c\/p\u003e\n\u003cp\u003eThe S56 fits into tapped holes in machine frames, fixtures, jigs, tooling plates, and mechanical subassemblies where repeatable positioning or soft detent action is required. It is a standard-length plunger style appropriate for general industrial and light manufacturing applications. No locking element is incorporated, so the plunger can be installed and adjusted without thread-locking compounds unless the application requires them.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 thread with 1 inch thread length for standard tapped-hole installation\u003c\/li\u003e\n  \u003cli\u003eSteel body and steel nose for durability in industrial environments\u003c\/li\u003e\n  \u003cli\u003e3 pound initial end force and 15 pound final end force for light detent and positioning use\u003c\/li\u003e\n  \u003cli\u003ePlunger projection of 3\/16 inch in standard-length configuration\u003c\/li\u003e\n  \u003cli\u003ePlunger diameter of 0.133 to 0.135 inches for consistent spring action\u003c\/li\u003e\n  \u003cli\u003eNo locking element  -  straightforward installation and adjustment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install threaded spring plunger for tapped 5\/16-18 holes in mechanical fixtures, jigs, tooling plates, and light industrial assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall into a clean, properly tapped 5\/16-18 through or blind hole using a hex key or appropriate drive tool. Ensure the mating hole depth accommodates the 1 inch body length plus desired plunger travel. De-energize or lock out any moving equipment before installing or removing spring plungers in active assemblies. Apply thread-locking compound only if the application requires a fixed installation, as the part has no integrated locking element.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Plunger Diameter\u003c\/strong\u003e: 0.133 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.135 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 15 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\u003ePlunger Length Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: No\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: S56\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":52072715125042,"sku":"S56","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4446f644a05560944a2a73e4824fa63d.jpg?v=1790049960","url":"https:\/\/voomisupply.com\/products\/vlier-s56-threaded-spring-plunger-5-16-18-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
