The body is machined from steel with a phenolic nose, offering corrosion resistance at the contact point and reduced marring on mating surfaces. The plunger threads into a 3\/8-16 tapped hole with a 1-1\/8 inch thread length, delivering an initial end force of 2.8 pounds and a final end force of 7.2 pounds. The plunger diameter ranges from 0.185 to 0.187 inches with a 3\/16 inch projection. This type of hardware is installed by machinists, toolmakers, and mechanical assemblers in production and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThe NS59 suits applications where repeatable detent positioning or light retention force is required. Common install scenarios include machine tool fixtures, jigs, assembly tooling, industrial equipment panels, and motion-control mechanisms. The phenolic nose material makes it appropriate for use against softer mating surfaces where a steel-on-steel contact point would cause galling or unwanted wear. This plunger is intended for installations where no locking element is required on the threaded body.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 thread size with 1-1\/8 inch thread length for secure installation in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e2.8 pound initial end force and 7.2 pound final end force for consistent detent performance\u003c\/li\u003e\n  \u003cli\u003eSteel body construction for durability in industrial environments\u003c\/li\u003e\n  \u003cli\u003ePhenolic nose minimizes surface damage on mating components\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch plunger projection with a diameter of 0.185 to 0.187 inches\u003c\/li\u003e\n  \u003cli\u003eNo locking element on the threaded body, allowing straightforward adjustment and removal\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 machinery, fixtures, and tooling assemblies requiring a 3\/8-16 tapped hole with standard thread length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or mechanical assemblers using a hex wrench or spanner appropriate for the plunger body. Ensure the receiving tapped hole is clean and free of debris before threading in the plunger. De-energize or lock out any powered equipment before installing or adjusting spring plungers in automated or motorized assemblies. Do not overtighten, as the steel body can distort the threaded bore if excessive torque is applied without a locking element present.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Plunger Diameter\u003c\/strong\u003e: 0.185 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.187 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 2.8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 7.2 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\u003eLocking Element\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Standard\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: NS59\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":52078277460274,"sku":"NS59","price":16.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7f39b487e35d05a021c00c7f4e9704a_7d2e7a5f-aae2-4deb-bb8e-ea84c7adbcce.jpg?v=1790053984","url":"https:\/\/voomisupply.com\/products\/vlier-ns59-threaded-spring-plunger-3-8-16-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
