It features a 1\/4-20 thread size, a steel body, and a steel ball measuring 0.125 inches in diameter. The body length is 0.531 inches, and the maximum ball reach is 0.035 inches. Initial end force is 2 pounds, with a final end force of 4 pounds. A built-in locking element secures the assembly after installation. Identified by a purple color code, this is one of the smallest and lightest spring-loaded devices in the VLIER lineup, making it suited for tight-space applications where repeatable, low-force positioning is required.\u003c\/p\u003e\u003cp\u003eThe BL54N is used in applications requiring controlled, repeatable detent or positioning force in mechanical assemblies. Typical uses include fixture tooling, jigs, latching mechanisms, and positioning devices found in industrial equipment, machine tooling, and precision manufacturing. The 1\/4-20 thread allows installation into standard tapped holes. This part is installed by mechanical assemblers, tool and die technicians, and maintenance professionals working in manufacturing and industrial environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 thread size for installation into standard tapped holes\u003c\/li\u003e\n\u003cli\u003eSteel body and steel ball for durability in industrial environments\u003c\/li\u003e\n\u003cli\u003e2-pound initial end force and 4-pound final end force for controlled, repeatable positioning\u003c\/li\u003e\n\u003cli\u003eMaximum ball reach of 0.035 inches for precise detent engagement\u003c\/li\u003e\n\u003cli\u003eBuilt-in locking element to secure plunger position after adjustment\u003c\/li\u003e\n\u003cli\u003eCompact 0.531-inch body length suited for tight-clearance assemblies\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 a 1\/4-20 threaded ball plunger with controlled end force and a locking element.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by threading the BL54N into a pre-tapped 1\/4-20 hole using an appropriate wrench or driver. Disengage and de-energize any powered or pressurized equipment before servicing the assembly. Do not overtighten, as excessive torque can damage the locking element or distort the body. Verify ball reach and end force are appropriate for the detent application before final assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.531 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Ball Reach\u003c\/strong\u003e: 0.035 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 4 pounds\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: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Code\u003c\/strong\u003e: Purple\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: BL54N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":68081179197746,"sku":"BL54N","price":15.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f5a8546066809b51157430549426667.jpg?v=1793134572","url":"https:\/\/voomisupply.com\/products\/vlier-bl54n-threaded-ball-plunger-1-4-20-steel-locking","provider":"Voomi Supply","version":"1.0","type":"link"}
