The body is machined from steel with a Delrin nose, providing a firm yet low-friction contact point. Thread size is 3\/8-16 with a thread length of 0.625 inches and a stubby plunger projection of 0.11 inches. Initial end force is 4.5 pounds and final end force is 18.5 pounds, making this plunger suitable for applications requiring a defined resistance or detent feel under load. Mechanical assemblers and maintenance technicians install this type of component in fixtures, jigs, tooling plates, and machine housings.\u003c\/p\u003e\n\u003cp\u003eThis plunger is used in light industrial settings where a spring-loaded contact point is needed to locate, retain, or index a moving part. The stubby plunger style and compact 0.625-inch body length make it well suited for installations with limited axial clearance. It threads directly into a tapped 3\/8-16 hole and requires no additional hardware. Typical applications include tooling fixtures, panel assemblies, sliding mechanisms, and equipment housings where repeatable positioning is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-16 threaded body for direct installation into standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eStubby plunger style with 0.11 inch projection for tight-clearance installations\u003c\/li\u003e\n  \u003cli\u003eSteel body construction for durability in industrial environments\u003c\/li\u003e\n  \u003cli\u003eDelrin nose material provides low-friction, non-marring contact\u003c\/li\u003e\n  \u003cli\u003e4.5 pound initial end force and 18.5 pound final end force for defined detent resistance\u003c\/li\u003e\n  \u003cli\u003eNo locking element  -  standard installation and removal with common hand tools\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard OEM-style threaded spring plunger for use in any assembly or fixture with a tapped 3\/8-16 hole requiring spring-loaded positioning or detent retention.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with standard hand tools sized for a 3\/8-16 threaded fastener. Ensure the receiving hole is clean and properly tapped to 3\/8-16 before threading in the plunger. Do not overtighten, as excessive torque can damage the spring mechanism or body threads. Confirm plunger projection and force values are appropriate for the application before final assembly.\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: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.186 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.11 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Stubby\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 4.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 18.5 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: Delrin\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: NM58\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51972115235122,"sku":"NM58","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c98ab47e1683d46187d52d7b30d1a77.jpg?v=1789962878","url":"https:\/\/voomisupply.com\/products\/vlier-nm58-threaded-spring-plunger-3-8-16-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
