It features an M12x1.75 threaded body with a body length of 1.14 inches and a non-locking plunger that delivers an initial end force of 1 pound and a final end force of 10 pounds. The maximum plunger diameter is 0.236 inches with a plunger projection of 0.236 inches. A locking element is included to secure the plunger position after installation. This part is typically installed by maintenance technicians and mechanical assemblers working in production tooling, fixtures, and equipment.\u003c\/p\u003e\u003cp\u003eThe SSLM12P is suited for applications where repeatable positioning or detent action is required in metal or composite assemblies. The knurled knob allows for hand-adjustment without additional tools, making it appropriate for fixtures, jigs, and machine components that require periodic plunger engagement or disengagement. The M12x1.75 thread fits standard metric tapped holes and is common in industrial machinery and assembly tooling environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNon-locking plunger type for smooth, repeatable engagement\u003c\/li\u003e\n\u003cli\u003eKnurled knob handle allows tool-free hand adjustment\u003c\/li\u003e\n\u003cli\u003eEnd force range from 1 pound initial to 10 pounds final for consistent detent resistance\u003c\/li\u003e\n\u003cli\u003eLocking element included to secure plunger position in the body\u003c\/li\u003e\n\u003cli\u003eM12x1.75 metric thread for compatibility with standard tapped metric holes\u003c\/li\u003e\n\u003cli\u003ePlunger diameter tolerance of +0.000 \/ -0.001 inches for precise fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit spring plunger for industrial fixtures, jigs, and mechanical assemblies using standard M12x1.75 metric threaded bores.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by threading the plunger body into a pre-tapped M12x1.75 metric hole using the knurled knob or an appropriate wrench on the shoulder. Ensure the mating bore is clean and free of debris before threading in the component. Engage the locking element after reaching the desired depth to prevent back-out during operation. Power down or de-energize any equipment before servicing or replacing spring plungers in live machinery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M12x1.75\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.905 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1.14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\/Shoulder\u003c\/strong\u003e: 0.905 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Type\u003c\/strong\u003e: Non-Locking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKnob Style\u003c\/strong\u003e: Knurled\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.236 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.236 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Length\u003c\/strong\u003e: 1.535 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.984 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.315 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead and Shoulder Height\u003c\/strong\u003e: 0.630 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 10 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: Yes\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: SSLM12P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLIER","offers":[{"title":"Default Title","offer_id":52014677000498,"sku":"SSLM12P","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cf16ebb7eaaeca7d38bb64c70f9181d6_66992910-8896-49f9-a47e-09af60d47e3e.jpg?v=1790007180","url":"https:\/\/voomisupply.com\/products\/vlier-sslm12p-spring-plunger-m12x1-75-knurled-knob","provider":"Voomi Supply","version":"1.0","type":"link"}
