The plunger body is constructed from stainless steel, with a Delrin nose for smooth, low-friction contact against mating surfaces. It accepts an 8-32 thread with a thread length of 0.437 inches and delivers an initial end force of 1.50 pounds and a final end force of 4.75 pounds. Maximum plunger diameter is 0.07 inches with a projection of 0.052 inches. This part is installed by machinists, maintenance technicians, and assembly professionals working with precision mechanical components.\u003c\/p\u003e\u003cp\u003eThe SSMD50A is suited for applications requiring a compact, corrosion-resistant spring plunger in tight spaces where a standard-length body will not fit. The stubby body length of 0.437 inches makes it appropriate for thin panels, shallow housings, and close-tolerance assemblies across industrial, automation, and instrumentation applications. It installs directly into a tapped 8-32 hole without additional hardware. No locking element is present, so thread adhesive or a jam nut may be used when a fixed installation position is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStubby body profile at 0.437 inches body length for shallow or tight installation clearances\u003c\/li\u003e\n\u003cli\u003eStainless steel body provides corrosion resistance in demanding environments\u003c\/li\u003e\n\u003cli\u003eDelrin nose reduces friction and wear on mating contact surfaces\u003c\/li\u003e\n\u003cli\u003e1.50 lb initial end force and 4.75 lb final end force for light-to-moderate detent action\u003c\/li\u003e\n\u003cli\u003eStandard 8-32 thread installs directly into a tapped hole\u003c\/li\u003e\n\u003cli\u003eNo locking element  -  compatible with thread-lock compounds or jam nut retention\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-install OEM-style threaded spring plunger for any assembly with a tapped 8-32 hole requiring a stubby-profile detent or positioning element.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or qualified assembly technician should install this plunger into a properly tapped 8-32 hole using an appropriate hex key or driver. Verify thread engagement depth against the 0.437-inch thread length before final assembly. If a fixed installation position is required, apply a thread-locking compound before installation. Ensure the plunger nose travel path is clear of obstructions before closing the assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.437 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.437 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Length Type\u003c\/strong\u003e: Stubby\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.07 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.052 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 1.50 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 4.75 pounds\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: None\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: SSMD50A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51971974005042,"sku":"SSMD50A","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5db6eb12772afc5c4b476f0303b9d48b.jpg?v=1789959826","url":"https:\/\/voomisupply.com\/products\/vlier-ssmd50a-threaded-spring-plunger-8-32-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
