The plunger features a 5\/8-11 thread size with a 1 inch thread length and a maximum plunger diameter of 0.373 inches. It delivers an initial end force of 5 pounds and a final end force of 10 pounds, making it well suited for applications requiring controlled, repeatable positioning under moderate spring load. A licensed machinist or industrial maintenance technician typically installs this component in jigs, fixtures, and assembly tooling.\u003c\/p\u003e\n\u003cp\u003eThis plunger is used in industrial and manufacturing environments where a locking mechanism is required to hold a position under load. The knobless threaded stud design allows the unit to be installed in locations where a protruding knob would interfere with adjacent components or tooling surfaces. The 1-5\/16 inch length under the head and a plunger projection of 5\/16 inch make it appropriate for moderate-depth mounting applications. It is commonly found in machine tool fixtures, jigs, and precision workholding devices in both production and maintenance shop settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLocking plunger design holds position under load without external fastening\u003c\/li\u003e\n  \u003cli\u003eKnobless threaded stud configuration for low-profile installation in tight spaces\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 external thread with 1 inch thread length for secure mounting\u003c\/li\u003e\n  \u003cli\u003eInitial end force of 5 pounds rising to a final end force of 10 pounds\u003c\/li\u003e\n  \u003cli\u003ePlunger projection of 5\/16 inch with a total plunger length of 2.186 inches\u003c\/li\u003e\n  \u003cli\u003eStud thread size of 1\/2-13 for compatibility with standard threaded mounting holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install component for industrial fixtures and workholding assemblies that accept a 5\/8-11 threaded locking plunger with a knobless stud mount.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or mechanical maintenance technician using standard hand tools. Ensure the mounting surface is de-energized and any moving machinery is fully stopped and locked out before installing or removing the plunger. Thread the stud into the receiving hole to the specified engagement depth and verify the locking element engages and releases smoothly before returning the assembly to service. Do not exceed the rated end force for the plunger in the installed application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStud Thread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.373 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 Projection\u003c\/strong\u003e: 0.3125 inches (5\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length\u003c\/strong\u003e: 2.186 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\/Shoulder\u003c\/strong\u003e: 1.3125 inches (1-5\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 7\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 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\u003ePlunger Type\u003c\/strong\u003e: 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\u003eLocking Element\u003c\/strong\u003e: Yes\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: 34240SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51718810206514,"sku":"34240SS","price":61.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e8d4fbac84130691fcf154815af5fa47_b9d40ebc-baa3-415b-b34b-9cf71f0df85c.jpg?v=1788555708","url":"https:\/\/voomisupply.com\/products\/gibraltar-34240ss-locking-plunger-5-8-11-threaded-stud","provider":"Voomi Supply","version":"1.0","type":"link"}
