The unit features an M12x1.75 thread with a 25mm thread length, a stainless steel body with a black finish, and a Delrin knob for hand operation. The plunger locks in the retracted position, preventing unintended extension during setup or adjustment. Initial end force measures 0.56 pounds and final end force measures 1.8 pounds, providing consistent, repeatable engagement. Machinists, fabricators, and maintenance technicians typically install and service this type of hardware.\u003c\/p\u003e\n\u003cp\u003eThis plunger fits standard M12x1.75 threaded bores found in jigs, fixtures, machine frames, and tooling plates. The locking mechanism allows the plunger to be held retracted while components are loaded or repositioned, then released to engage. The Delrin knob allows tool-free hand operation in production environments. With a body length of 1.2 inches and a plunger projection of 0.236 inches, the MSDKL50-G suits compact fixture designs where space is limited. It is appropriate for both light-duty workholding and general indexing use in shop and maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLocking plunger holds retracted position for hands-free component loading\u003c\/li\u003e\n  \u003cli\u003eM12x1.75 thread size with 25mm thread length for standard metric bore fitment\u003c\/li\u003e\n  \u003cli\u003eStainless steel body with black finish for corrosion resistance and clean appearance\u003c\/li\u003e\n  \u003cli\u003eDelrin knob allows tool-free hand operation\u003c\/li\u003e\n  \u003cli\u003eInitial end force of 0.56 pounds and final end force of 1.8 pounds for consistent engagement\u003c\/li\u003e\n  \u003cli\u003eCompact 1.2-inch body length suits space-constrained fixture and tooling designs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard M12x1.75 threaded bores in industrial jigs, fixtures, tooling plates, and machine frames requiring a locking plunger with a Delrin knob handle.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the plunger body into a prepared M12x1.75 tapped hole by hand or with a wrench on the 0.472-inch hex flat. Ensure the mating bore is clean and free of debris before threading in. Power down or de-energize any machine before servicing plungers installed in live tooling or indexing mechanisms. Do not exceed the rated end force to avoid premature wear on the plunger tip or mating surfaces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 25mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 0.56 pounds (2.5 N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 1.8 pounds (8 N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.314 inches (7.98mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.236 inches (5.99mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length\u003c\/strong\u003e: 1.85 inches (46.99mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Type\u003c\/strong\u003e: Locking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1.2 inches (30.48mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\/Shoulder\u003c\/strong\u003e: 0.98 inches (24.89mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.98 inches (24.89mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead and Shoulder Height\u003c\/strong\u003e: 0.87 inches (22.10mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.472 inches (11.99mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKnob Style\u003c\/strong\u003e: Delrin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: MSDKL50-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51722236657970,"sku":"MSDKL50-G","price":53.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/948cd623ac9b80ad886162365234422f.jpg?v=1788587946","url":"https:\/\/voomisupply.com\/products\/gibraltar-msdkl50-g-locking-knob-handle-plunger-m12x1-75","provider":"Voomi Supply","version":"1.0","type":"link"}
