Featuring an 8-32 thread size and a 5\/8 inch thread length, this plunger installs into a tapped bore and uses internal spring force to apply controlled end pressure against a mating surface or detent. The stainless steel body and nose offer corrosion resistance suitable for demanding environments. Initial end force is 0.70 pounds, middle end force is 1.50 pounds, and final end force is 2.30 pounds, giving technicians and machinists a predictable force curve across the full plunger travel range.\u003c\/p\u003e\u003cp\u003eThe SSPH51 is used in light-duty positioning, alignment, and detent applications across industrial machinery, tooling fixtures, jigs, and precision mechanical assemblies. Its compact 0.07 inch plunger diameter and 3\/32 inch projection make it well suited for tight-clearance installations where space is limited. This type of plunger is typically installed by machinists, tool and die makers, mechanical assemblers, and maintenance technicians working on production or service equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-32 thread size with 5\/8 inch thread length for standard tapped-bore installation\u003c\/li\u003e\n\u003cli\u003eStainless steel body and nose material for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e3\/32 inch plunger projection provides controlled engagement depth\u003c\/li\u003e\n\u003cli\u003eProgressive spring force: 0.70 lb initial, 1.50 lb middle, 2.30 lb final end force\u003c\/li\u003e\n\u003cli\u003eStandard plunger length type for drop-in replacement in existing assemblies\u003c\/li\u003e\n\u003cli\u003eNo locking element  -  free-spinning installation without thread locking feature\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for mechanical assemblies requiring an 8-32 threaded spring plunger with standard projection and stainless steel construction.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a properly tapped 8-32 bore in the receiving component. Power down or de-energize any equipment before servicing assemblies containing this plunger. A hex wrench sized to the 0.063 inch hex is used for installation and removal. Do not overtighten, as the plunger body is stainless steel and thread damage can result from excessive torque.\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: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 3\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Plunger Diameter\u003c\/strong\u003e: 0.069 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.070 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.063 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 0.70 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMiddle End Force\u003c\/strong\u003e: 1.50 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 2.30 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: Stainless Steel\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\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: SSPH51\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51971469738290,"sku":"SSPH51","price":16.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6ffe0e870bd4ef2be590539fc196a090_1e8986fa-752c-4f21-bfca-964f4b58b53d.jpg?v=1789957688","url":"https:\/\/voomisupply.com\/products\/vlier-ssph51-threaded-spring-plunger-8-32-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
