It features a 3\/8-16 thread size with a 0.75-inch thread length and delivers an initial end force of 1.5 pounds rising to a final end force of 8 pounds. The plunger diameter reaches a maximum of 0.186 inches with a tolerance of plus 0.001 inch, and the plunger projection measures 7\/32 inches (0.2188 inches). Constructed from stainless steel with a zinc finish, this plunger suits environments requiring corrosion resistance and consistent spring-loaded engagement.\u003c\/p\u003e\u003cp\u003eThe GIBRALTAR 34168 is suited for use in machine tool fixtures, panel assemblies, and equipment where a flush or recessed plunger mounting is required. The knobless threaded stud configuration allows the plunger to be installed directly into a tapped hole without an exposed head, making it practical in tight-clearance or flush-mount installations. This type of spring plunger is commonly installed by machinists, tool and die technicians, and maintenance mechanics working on precision equipment and industrial machinery.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNon-locking spring plunger with locking element present in the assembly for controlled retention\u003c\/li\u003e\n\u003cli\u003e3\/8-16 thread size with 0.75-inch thread length for direct installation into tapped holes\u003c\/li\u003e\n\u003cli\u003eSpring force range from 1.5 pounds initial to 8 pounds final end force\u003c\/li\u003e\n\u003cli\u003eMaximum plunger diameter of 0.186 inches with tight tolerance of plus 0.001 inch\u003c\/li\u003e\n\u003cli\u003eStainless steel construction with zinc finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eKnobless threaded stud style for flush or recessed panel mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-install spring plunger for tapped 3\/8-16 threaded holes in industrial fixtures, machine assemblies, and positioning equipment requiring non-locking spring-loaded engagement.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by threading the stud directly into a pre-tapped 3\/8-16 hole using a hex key or appropriate tool on the stud body. Ensure the receiving hole is clean and correctly tapped to thread depth before installation. De-energize or lock out any powered equipment before servicing assemblies containing spring plungers. Do not exceed the rated final end force by over-compressing the plunger during installation or operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStud Thread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 1.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 8 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.2188 inches (7\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.186 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Diameter Tolerance\u003c\/strong\u003e: plus 0.001 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlunger Length\u003c\/strong\u003e: 1.691 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\/Shoulder\u003c\/strong\u003e: 0.219 inches (7\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 13\/32 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: Threaded Stud without Knob\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: Zinc\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: 0.03 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: 34168\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51691693539634,"sku":"34168","price":46.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7ffcf2c850f33e09be54743448b74e6b_dc4bf382-7873-4ccc-84b5-6197d3d78979.jpg?v=1788288577","url":"https:\/\/voomisupply.com\/products\/gibraltar-34168-knob-handle-plunger-3-8-16-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
