This small-format, spring-loaded device uses a steel ball seated in a steel body to provide consistent, repeatable positioning and detent action. The 6-40 thread allows installation into tapped holes in tight-clearance applications. With a ball diameter of 0.078 inches, a body length of 0.312 inches, and a maximum ball reach of 0.023 inches, the B48 is one of the smallest and lightest spring-loaded plungers available for light-force indexing and positioning tasks. Initial end force is 0.5 pounds and final end force is 1 pound.\u003c\/p\u003e\n\u003cp\u003eThe B48 is suited for applications requiring controlled, light spring force in compact mechanical assemblies. Typical uses include panel detents, sliding mechanism indexing, and component positioning in instruments, jigs, fixtures, and light-duty industrial equipment. The controlled end force profile makes it appropriate for any assembly where a repeatable, low-force ball detent is needed without exceeding component stress limits. This plunger installs into standard 6-40 tapped holes and is suitable wherever a minimal footprint and low actuation force are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-40 thread size for installation in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eSteel body and steel ball for durability in mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003e0.5 pound initial end force and 1 pound final end force for light, controlled detent action\u003c\/li\u003e\n  \u003cli\u003e0.078 inch ball diameter and 0.312 inch body length for compact fitment\u003c\/li\u003e\n  \u003cli\u003e0.023 inch maximum ball reach suitable for shallow detent profiles\u003c\/li\u003e\n  \u003cli\u003eNo locking element  -  installs and adjusts without thread-locking features\u003c\/li\u003e\n  \u003cli\u003eColor code purple for quick field identification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or original-install threaded ball plunger for light-force detent and positioning applications using 6-40 tapped hole patterns in mechanical assemblies, fixtures, and instrumentation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the B48 directly into a pre-tapped 6-40 hole using an appropriate driver or wrench on the body flats. Ensure the mating hole is clean and correctly threaded before installation to avoid cross-threading the small-diameter fastener. De-energize or mechanically lock any moving assemblies before servicing plungers in active mechanisms. Do not overtighten, as the small thread size has limited torque capacity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 6-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.078 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.312 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Ball Reach\u003c\/strong\u003e: 0.023 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor Code\u003c\/strong\u003e: Purple\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: B48\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51971163685170,"sku":"B48","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0ec84a04a7bc1d1fafb1a012a481e56c.jpg?v=1789953911","url":"https:\/\/voomisupply.com\/products\/vlier-b48-threaded-ball-plunger-6-40-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
