The body and ball are both constructed from stainless steel with a passivated finish, providing corrosion resistance in demanding environments. This plunger features a 5\/16-18 thread, a ball diameter of 0.156 inches, and a body length of 0.72 inches. Initial end force is 4 pounds, with a final end force of 9 pounds, making it suitable for indexing, positioning, and light detent functions. A locking element is included to secure the plunger in place after installation. Machinists, toolmakers, and mechanical assembly technicians are the typical installers.\u003c\/p\u003e\u003cp\u003eThis ball plunger is intended for use in fixtures, jigs, tooling plates, and precision mechanical components where repeatable positioning or controlled resistance is required. The stainless steel construction makes it appropriate for clean-room, food-processing-adjacent, or corrosion-sensitive environments. Maximum ball reach is 0.04 inches, which suits applications requiring minimal protrusion and precise detent engagement. The 5\/16-18 thread allows direct installation into tapped holes in metal assemblies without additional hardware.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16-18 threaded body for direct installation into standard tapped holes\u003c\/li\u003e\n\u003cli\u003eStainless steel body and ball with passivated finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e4 pound initial end force and 9 pound final end force for controlled detent action\u003c\/li\u003e\n\u003cli\u003eMaximum ball reach of 0.04 inches for minimal protrusion applications\u003c\/li\u003e\n\u003cli\u003eIntegrated locking element secures plunger position after adjustment\u003c\/li\u003e\n\u003cli\u003eDesigned for controlled end-force indexing and positioning applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for precision mechanical assemblies requiring a 5\/16-18 threaded ball plunger with controlled end-force characteristics.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or mechanical assembly technicians using a standard hex wrench or spanner tool appropriate for the plunger body. Ensure the receiving tapped hole is clean and free of debris before threading in the plunger. Engage the locking element only after the plunger is set to the desired position. Do not overtighten, as this may damage the locking element or distort the threaded engagement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.72 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Ball Reach\u003c\/strong\u003e: 0.04 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 9 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Passivate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Controlled End Force\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: SSPHB56P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51997159031090,"sku":"SSPHB56P","price":50.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5fee91fcaa5f10b44e6ef2dc1b2d6ae8_75755300-22eb-4690-b391-f5857dfadcc5.jpg?v=1789993879","url":"https:\/\/voomisupply.com\/products\/vlier-ssphb56p-threaded-ball-plunger-5-16-18-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
