The plunger features a Delrin knob for manual actuation without tools and a spring-loaded nose that provides controlled end force ranging from 0.12 pounds initial to 0.36 pounds final. With a 1\/4-20 thread and 0.5 inches of thread length, this plunger installs into standard tapped holes in machine frames, fixtures, tooling plates, and enclosures. Machinists, maintenance technicians, and equipment builders commonly install this type of component during fixture setup or equipment assembly.\u003c\/p\u003e\u003cp\u003eThe DKN25-G suits light-duty positioning tasks in industrial equipment, jigs, fixtures, and panel assemblies where repeatable manual indexing is needed. The non-locking plunger design allows the nose to retract and extend freely under manual pressure, making it appropriate for applications that require frequent adjustment or quick-release indexing without additional fasteners or tools.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNon-locking plunger design for tool-free manual actuation\u003c\/li\u003e\n\u003cli\u003eDelrin knob provides comfortable grip and corrosion-resistant contact surface\u003c\/li\u003e\n\u003cli\u003e1\/4-20 thread for installation into standard tapped holes\u003c\/li\u003e\n\u003cli\u003eInitial end force of 0.12 pounds, final end force of 0.36 pounds for predictable spring resistance\u003c\/li\u003e\n\u003cli\u003eCompact body length of 0.63 inches suited for space-constrained assemblies\u003c\/li\u003e\n\u003cli\u003eMaximum plunger diameter of 0.16 inches with 0.13 inches of plunger projection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/4-20 tapped holes in mechanical fixtures, tooling plates, enclosures, and light industrial equipment where a non-locking spring plunger with a knob handle is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by threading the plunger body into a pre-tapped 1\/4-20 hole by hand or with a wrench on the hex flat. Ensure the mating hole depth and thread engagement are sufficient to support the specified end forces without bottoming the plunger body. De-energize or secure any moving assembly before servicing adjacent components. Do not exceed the rated end force range to avoid spring fatigue or premature wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.5 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: Delrin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.63 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\/Shoulder\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Length\u003c\/strong\u003e: 0.97 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead and Shoulder Height\u003c\/strong\u003e: 0.47 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 0.36 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocking Element\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: DKN25-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51698214338866,"sku":"DKN25-G","price":18.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a22a550652c61fd8d9a406072ec16641.jpg?v=1788359480","url":"https:\/\/voomisupply.com\/products\/gibraltar-dkn25-g-knob-handle-spring-plunger-1-4-20","provider":"Voomi Supply","version":"1.0","type":"link"}
