The plunger features a 1\/2-13 external thread with a thread length of 0.875 inches and a maximum plunger diameter of 0.249 inches. End force ranges from 2.5 pounds initial to 10 pounds final, making it suitable for light-duty clamping and locating tasks. Constructed from steel with a zinc finish, the 34150 offers corrosion resistance for general industrial and shop environments. The knobless threaded stud design allows installation into tapped holes where a flush or recessed head profile is needed.\u003c\/p\u003e\n\u003cp\u003eThe GIBRALTAR 34150 is used in fixture plates, jigs, machine tool setups, and assembly tooling where repeatable plunger positioning is required. The non-locking plunger type allows smooth in-and-out travel without a twist-lock mechanism, which is preferred in high-cycle or quick-release applications. The threaded stud style, without an attached knob, is commonly selected when actuation will be handled by tooling, cams, or contact surfaces rather than by hand. This part is sold individually and is appropriate for both production floor and maintenance shop use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNon-locking plunger for smooth, unrestricted axial travel\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 external thread with 0.875 inch thread length for secure installation in tapped fixtures\u003c\/li\u003e\n  \u003cli\u003eEnd force range: 2.5 pounds initial to 10 pounds final for light-duty locating applications\u003c\/li\u003e\n  \u003cli\u003eKnobless threaded stud configuration allows flush or recessed mounting\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc finish for general-purpose corrosion resistance\u003c\/li\u003e\n  \u003cli\u003ePlunger diameter tolerance of plus 0.001 inches for consistent fit in close-tolerance bores\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for standard 1\/2-13 tapped fixture plates, jig bodies, and tooling assemblies requiring a non-locking threaded plunger with a 0.249 inch maximum plunger diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the stud body into a prepared 1\/2-13 tapped hole using a wrench on the head flats or appropriate tooling. Ensure the mating bore for the plunger tip is clean and free of burrs before installation to prevent damage to the plunger diameter tolerance. Secure the plunger to the desired depth and verify free axial plunger travel before placing the assembly into service. No special certifications are required for installation, but standard machine shop practices and torque judgment should be applied to avoid thread stripping.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStud Thread Size\u003c\/strong\u003e: 3\/8-16\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: Threaded Stud without Knob\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 2.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 10 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.249 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Diameter Tolerance\u003c\/strong\u003e: plus 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length\u003c\/strong\u003e: 1.937 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\/Shoulder\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.4375 inches\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 34150\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51720926757170,"sku":"34150","price":37.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/21384eb9701f8780b06b51892542a118.jpg?v=1788571055","url":"https:\/\/voomisupply.com\/products\/gibraltar-34150-knob-handle-plunger-1-2-13-non-locking","provider":"Voomi Supply","version":"1.0","type":"link"}
