Built from steel with a zinc chromate finish, it features a 1\/4-20 thread size and a 0.4-inch thread length, making it suitable for light-duty clamping and retention tasks. The knurled knob provides a secure, non-slip grip for manual operation without tools. Initial end force is 0.5 pounds, with a final end force of 2 pounds, giving the installer repeatable, controlled engagement. Machinists, toolmakers, and maintenance technicians typically specify this type of plunger for jigs, fixtures, and panel assemblies.\u003c\/p\u003e\n\u003cp\u003eThis plunger is suited for use in manufacturing fixtures, machine tool setups, and control panel assemblies where a compact, manually actuated locking plunger is required. The locking knob style allows the plunger to be retracted and held in position while components are repositioned, then released for positive engagement. At 0.05 pounds, the 54610XG is a lightweight component well matched to applications with limited clearance and space constraints. It is sold individually and is appropriate for both original equipment builds and maintenance replacement situations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLocking plunger type holds retracted position for hands-free component handling\u003c\/li\u003e\n  \u003cli\u003eKnurled knob for positive manual grip without additional tooling\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 thread size with 0.4-inch thread length for standard tapped-hole installation\u003c\/li\u003e\n  \u003cli\u003eInitial end force of 0.5 pounds, final end force of 2 pounds for light controlled engagement\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc finish for corrosion resistance in shop environments\u003c\/li\u003e\n  \u003cli\u003eCompact body length of 0.525 inches suits tight clearance installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 locking knob handle plunger for use in industrial fixtures, jigs, and mechanical assemblies requiring a compact manual indexing or retention plunger.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the 54610XG into a pre-tapped 1\/4-20 hole by hand or with a wrench on the knob body, taking care not to overtighten and risk stripping the threads. Verify the plunger projection of 0.125 inches clears all adjacent components before final installation. No special certifications are typically required for fixture hardware of this type, but follow applicable facility safety lockout procedures when servicing live equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 0.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 0.525 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\/Shoulder\u003c\/strong\u003e: 0.4 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 Height\u003c\/strong\u003e: 0.28 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead and Shoulder Height\u003c\/strong\u003e: 0.41 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.123 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length\u003c\/strong\u003e: 0.805 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Diameter Tolerance\u003c\/strong\u003e: +0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Type\u003c\/strong\u003e: Locking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKnob Style\u003c\/strong\u003e: Knurled\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 Chromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: 54610XG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51711026430258,"sku":"54610XG","price":22.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc6e7b55ef8c2da09806440636452019.jpg?v=1788473671","url":"https:\/\/voomisupply.com\/products\/gibraltar-54610xg-locking-knob-handle-plunger-1-4-20","provider":"Voomi Supply","version":"1.0","type":"link"}
