This non-locking plunger features a knurled knob head and a steel body with a zinc gold chromate finish. It is threaded M12x1.75 with a body length of 1.14 inches and delivers a spring end force range of 1 pound initial to 10 pounds final. The maximum plunger diameter is 0.236 inches with a plunger projection of 0.236 inches. Machinists, tool and die technicians, and maintenance mechanics install this type of component in jigs, fixtures, machine tool tables, and similar equipment requiring repeatable positioning.\u003c\/p\u003e\u003cp\u003eThis spring plunger is suited for use in light-duty to moderate-duty fixturing applications where controlled spring force is needed to hold a workpiece or component in a repeatable indexed position. The knurled knob allows hand adjustment without tools, making it practical for setups that require frequent repositioning. The zinc gold chromate finish provides corrosion resistance for general shop and industrial environments. It is sold individually and is appropriate for both original equipment builds and maintenance replacement in existing fixture assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM12x1.75 thread size with 0.905 inches of thread length for secure installation in threaded housings\u003c\/li\u003e\n\u003cli\u003eNon-locking plunger type with 1 pound initial end force and 10 pounds final end force\u003c\/li\u003e\n\u003cli\u003eKnurled knob head style allows tool-free hand adjustment in the field\u003c\/li\u003e\n\u003cli\u003eSteel construction with zinc gold chromate finish for corrosion resistance in shop environments\u003c\/li\u003e\n\u003cli\u003eMaximum plunger diameter of 0.236 inches with plunger projection of 0.236 inches\u003c\/li\u003e\n\u003cli\u003eLocking element included to secure the plunger assembly at the desired position\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style or replacement spring plunger for industrial fixtures, jigs, machine tool tables, and mechanical assemblies using M12x1.75 threaded bores requiring a knob handle style plunger.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSpring plungers of this type are installed by maintenance mechanics and toolroom technicians using standard hand tools or an open-end wrench on the threaded body. Always confirm the receiving bore thread specification matches M12x1.75 before installation to avoid cross-threading. De-energize or lock out any associated machine or fixture before servicing or replacing a spring plunger component. Do not over-tighten the body into the threaded housing, as this can compress the spring beyond its rated travel and reduce end force accuracy.\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\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\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\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\u003eInitial End Force\u003c\/strong\u003e: 1 pound (4.45 N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 10 pounds (44.5 N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Gold Chromate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: GIBRALTAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MKNL-4-PT-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51701231452466,"sku":"MKNL-4-PT-G","price":27.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b675eebfb10ffad23161d9063ca5acde.jpg?v=1788400289","url":"https:\/\/voomisupply.com\/products\/gibraltar-mknl-4-pt-g-knob-handle-spring-plunger-m12x1-75","provider":"Voomi Supply","version":"1.0","type":"link"}
