It features a 1\/2-13 thread with a 1-1\/4 inch thread length and a 1-1\/4 inch body length. The plunger nose measures between 0.246 and 0.248 inches in diameter with a 1\/4 inch projection. Initial end force is 2.7 pounds and final end force is 9.3 pounds, making it suitable for applications requiring consistent, repeatable spring-loaded engagement. The stainless steel body provides corrosion resistance in demanding environments, while the Delrin nose reduces wear on mating surfaces. Machinists, maintenance technicians, and mechanical assemblers install this type of plunger.\u003c\/p\u003e\u003cp\u003eThe SSSD61 is used in jigs, fixtures, tooling plates, and machine assemblies where a spring-loaded ball or nose plunger is needed to hold a component in a defined position without a permanent lock. It is suited for both light industrial and precision mechanical applications where smooth, repeatable detent action is required. The standard plunger length type makes it a straightforward drop-in solution for common threaded plunger locations in existing assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 thread size with 1-1\/4 inch thread length for secure installation in standard tapped holes\u003c\/li\u003e\n\u003cli\u003eStainless steel body for corrosion resistance in wet or harsh environments\u003c\/li\u003e\n\u003cli\u003eDelrin nose material reduces wear on mating contact surfaces\u003c\/li\u003e\n\u003cli\u003e2.7 lb initial end force and 9.3 lb final end force for controlled detent engagement\u003c\/li\u003e\n\u003cli\u003e0.246 to 0.248 inch plunger diameter with 1\/4 inch projection\u003c\/li\u003e\n\u003cli\u003eNo locking element  -  free-spinning for easy 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 spring plunger for mechanical assemblies using a 1\/2-13 threaded plunger bore with standard 1-1\/4 inch thread depth.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machining or tooling technicians using a standard hex wrench or spanner tool appropriate for the body size. Always ensure the mating tapped hole is clean and free of debris before threading in the plunger. Do not overtighten, as this can distort the body or restrict plunger travel. Confirm plunger projection and spring force are appropriate for the detent load of the specific assembly before final installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Plunger Diameter\u003c\/strong\u003e: 0.246 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.248 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 2.7 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 9.3 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\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: SSSD61\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":52062261313842,"sku":"SSSD61","price":24.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7f39b487e35d05a021c00c7f4e9704a_2ae8679a-f6be-4a38-9bc1-c4eca17bdbdf.jpg?v=1790042340","url":"https:\/\/voomisupply.com\/products\/vlier-sssd61-threaded-spring-plunger-1-2-13-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
