It features a 1\/4-20 thread with a 1 inch thread length and a 3\/16 inch plunger projection. The steel body and steel nose deliver consistent durability in industrial and trade applications. Initial end force is 3 pounds and final end force is 13 pounds, making the S54 suitable for light-duty detent and positioning tasks. Machinists, tool and die technicians, and mechanical assembly professionals typically specify and install this component.\u003c\/p\u003e\n\u003cp\u003eThe S54 is used in jigs, fixtures, tooling plates, and mechanical assemblies where repeatable spring-loaded indexing or detent positioning is required. The 1\/4-20 thread allows installation into standard tapped holes. Its compact plunger diameter of 0.118 inches and 3\/16 inch projection suit applications with limited clearance. This plunger is appropriate for both light production tooling and maintenance repair scenarios in manufacturing and industrial environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 thread with 1 inch thread length for standard tapped-hole installation\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch plunger projection with standard plunger length type\u003c\/li\u003e\n  \u003cli\u003e3 pound initial end force and 13 pound final end force for light-duty detent applications\u003c\/li\u003e\n  \u003cli\u003eSteel body and steel nose construction for durability in industrial use\u003c\/li\u003e\n  \u003cli\u003ePlunger diameter range 0.117 to 0.118 inches for precise fitment\u003c\/li\u003e\n  \u003cli\u003eNo locking element  -  free-spinning installation for straightforward positioning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style threaded spring plunger for use in standard 1\/4-20 tapped holes in jigs, fixtures, tooling plates, and mechanical positioning assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the S54 into a pre-tapped 1\/4-20 hole using a hex key or slotted driver, depending on the drive style of the plunger body. Ensure the mating bore is clean and free of chips or debris before installation. De-energize or lock out any machinery before servicing assemblies that contain spring plungers. Do not overtighten, as this can compress the spring beyond its rated travel and reduce functional end force.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\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: 0.117 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.118 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: 13 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: S54\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51972889608498,"sku":"S54","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b1045117ab5d34017ca6fb2b78edcc1.jpg?v=1789971103","url":"https:\/\/voomisupply.com\/products\/vlier-s54-threaded-spring-plunger-1-4-20-1in-thread","provider":"Voomi Supply","version":"1.0","type":"link"}
