The body is machined from stainless steel and accepts a 3\/8-16 thread, making it straightforward to install in a tapped hole using standard hand tools. The plunger nose is Delrin, which provides low friction and wear resistance against mating surfaces. Initial end force is 1.5 pounds, with a final end force of 5 pounds, giving technicians a predictable and repeatable engagement feel. Thread length and body length are each 0.625 inches, keeping the installed footprint compact for tight-clearance designs.\u003c\/p\u003e\n\u003cp\u003eThis plunger fits residential and commercial mechanical, industrial, and manufacturing assembly applications where positive, spring-loaded detent action is needed without a locking element. The stubby plunger projection of 0.11 inches and a maximum plunger diameter of 0.186 inches suit designs with minimal clearance between mating components. Machinists, maintenance technicians, and mechanical assemblers typically install this part when a light, consistent detent or positioning stop is required in a tapped hole location.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel body for corrosion resistance in demanding environments\u003c\/li\u003e\n  \u003cli\u003eDelrin nose reduces friction and protects mating surfaces from galling\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 thread size allows installation with standard taps and tooling\u003c\/li\u003e\n  \u003cli\u003eStubby profile with 0.11 inches projection suited for tight-clearance assemblies\u003c\/li\u003e\n  \u003cli\u003e1.5 pound initial end force and 5 pound final end force for consistent detent feel\u003c\/li\u003e\n  \u003cli\u003eNo locking element simplifies removal and repositioning during assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style threaded spring plunger for any assembly or fixture with a 3\/8-16 tapped hole requiring a stubby spring detent with low-to-moderate end force.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the SSMD59 into a properly tapped 3\/8-16 hole using a hex key or appropriate driver on the body. Ensure the mating hole is clean and free of debris before installation. Do not overtighten, as excessive torque can distort the stainless steel body or restrict plunger travel. Verify plunger projection and force requirements against the assembly specification before final seating.\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\u003ePlunger 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\u003eInitial End Force\u003c\/strong\u003e: 1.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Stubby\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Stainless 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: SSMD59\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51994839154994,"sku":"SSMD59","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/696fbbebf957fc45371fc43d896f566a.jpg?v=1789992204","url":"https:\/\/voomisupply.com\/products\/vlier-ssmd59-threaded-spring-plunger-3-8-16-stubby","provider":"Voomi Supply","version":"1.0","type":"link"}
