The body and ball are both constructed from stainless steel, providing corrosion resistance in demanding environments. The plunger delivers an initial end force of 6.75 pounds and a final end force of 12.36 pounds, making it suitable for controlled-force applications where repeatable engagement is critical. A locking element is integrated into the design to secure the plunger after installation. This part is installed by machinists, maintenance technicians, and mechanical assemblers working on fixtures, jigs, tooling, and OEM equipment.\u003c\/p\u003e\u003cp\u003eThe SBM12N is suited for use in controlled end-force applications where side-load tolerance is required. Its compact form factor makes it one of the smallest and lightest spring-loaded positioning devices available in the M12 thread class. Typical install scenarios include machine tool fixtures, assembly jigs, dial mechanisms, and industrial equipment requiring repeatable tactile detent positions. The stainless steel construction makes it appropriate for wash-down, food processing, or corrosive-environment settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM12 x 1.75 thread size with 1.75 mm thread pitch for standard metric installation\u003c\/li\u003e\n\u003cli\u003eStainless steel body and stainless steel ball for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eInitial end force of 6.75 pounds and final end force of 12.36 pounds for controlled engagement\u003c\/li\u003e\n\u003cli\u003eMaximum ball reach of 0.098 inches (2.50 mm) for precise detent depth\u003c\/li\u003e\n\u003cli\u003eIntegrated locking element to prevent backing out after installation\u003c\/li\u003e\n\u003cli\u003eSide-load tolerant design suitable for off-axis force applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any threaded bore or tapped hole accepting an M12 x 1.75 metric thread, including machine fixtures, jigs, tooling plates, and mechanical assemblies requiring spring-loaded ball detent or positioning functions.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or mechanical technicians using a standard hex wrench or spanner sized for the body. Ensure the mating tapped hole is clean and free of debris before threading in the plunger. De-energize or lock out any powered equipment before servicing assemblies containing this plunger. The integrated locking element should be engaged per the manufacturer torque guidance to prevent loosening under vibration  -  do not overtighten, as this may restrict ball movement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M12 x 1.75\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 1.75 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.315 inches (8.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Ball Reach\u003c\/strong\u003e: 0.098 inches (2.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.866 inches (22.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 6.75 pounds (30.00 N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 12.36 pounds (55.00 N)\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\u003eLocking Element\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Code\u003c\/strong\u003e: Purple\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: SBM12N\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":51980107579698,"sku":"SBM12N","price":18.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/55b5ee238003862644a3089d06b84424_59dbce2b-39c2-4b70-9c8d-cb8ee9327ef7.jpg?v=1789981319","url":"https:\/\/voomisupply.com\/products\/vlier-sbm12n-threaded-ball-plunger-m12-x-1-75-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
