It features a 1\/4-20 thread with a 1 inch thread length and a steel body for durability in demanding environments. The phenolic nose resists wear and reduces marring on mating surfaces. With an initial end force of 3 pounds and a final end force of 13 pounds, it delivers consistent, repeatable spring tension suited to precision fit-up work. Machinists, tool and die technicians, and mechanical assembly specialists are the primary installers of this component.\u003c\/p\u003e\u003cp\u003eThis spring plunger is used in jigs, fixtures, tooling plates, and machine components where controlled detent or positioning force is needed. The 1\/4-20 threaded body allows installation into standard tapped holes in steel, aluminum, or plastic workpieces. The 3\/16 inch plunger projection provides adequate engagement depth for most light-load indexing applications. It is suited to both production tooling environments and custom fixture builds in manufacturing and fabrication settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 thread for installation into standard tapped holes\u003c\/li\u003e\n\u003cli\u003e1 inch thread length and 1 inch steel body length for secure engagement\u003c\/li\u003e\n\u003cli\u003ePhenolic nose material minimizes surface marring on mating components\u003c\/li\u003e\n\u003cli\u003e3 pound initial end force and 13 pound final end force for controlled detent action\u003c\/li\u003e\n\u003cli\u003ePlunger diameter range of 0.116 to 0.118 inches for consistent fit\u003c\/li\u003e\n\u003cli\u003eNo locking element  -  straightforward threaded installation and removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for standard 1\/4-20 tapped bore applications in industrial jigs, fixtures, and tooling assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or mechanical assembly technicians using a standard hex key or spanner wrench appropriate for the plunger body. The mating hole must be tapped to 1\/4-20 specification and kept free of debris before threading in the plunger. Power down or de-energize any associated machinery before servicing components in the assembly. Do not overtighten, as this can compress the internal spring beyond its rated travel and reduce detent performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 0.116 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: Phenolic\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\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: NS54\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":52096358744370,"sku":"NS54","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a25a6077af48ae196e8ff7bfecfa6606.jpg?v=1790066355","url":"https:\/\/voomisupply.com\/products\/vlier-ns54-threaded-spring-plunger-1-4-20-steel-body","provider":"Voomi Supply","version":"1.0","type":"link"}
