The plunger features a 3\/8-16 thread with a 0.75 inch thread length and a maximum plunger diameter of 0.186 inches. Spring end force ranges from 1.5 pounds initial to 8 pounds final, providing positive locking engagement. The threaded stud mount allows installation without an external knob, making it suitable for recessed or low-profile installations. Machinists, toolmakers, and maintenance technicians install this type of component in jigs, fixtures, and machine housings.\u003c\/p\u003e\u003cp\u003eThis plunger is used in industrial tooling, fixture plates, machine panels, and positioning assemblies where a spring-loaded locking element is needed to hold a component in a repeatable position. The knobless threaded stud design allows the plunger to be driven or adjusted with a wrench or socket rather than by hand, which suits enclosed or tight-clearance mounting locations. It is appropriate for both light and medium-duty indexing applications where controlled spring force is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLocking plunger type with positive locking element for indexed retention\u003c\/li\u003e\n\u003cli\u003eKnobless threaded stud (5\/16-18 stud thread) for wrench-driven installation\u003c\/li\u003e\n\u003cli\u003e3\/8-16 external thread with 0.75 inch thread length for secure panel mounting\u003c\/li\u003e\n\u003cli\u003eSpring end force from 1.5 pounds initial to 8 pounds final\u003c\/li\u003e\n\u003cli\u003ePlunger projection of 0.2188 inches with a diameter tolerance of +0.001 inches\u003c\/li\u003e\n\u003cli\u003eCompact head height of 0.406 inches suits low-profile assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct installation component for industrial jigs, fixtures, machine panels, and positioning assemblies requiring a 3\/8-16 threaded locking plunger with a knobless stud configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by threading the 3\/8-16 shank into a tapped hole in the mounting panel or fixture plate using a wrench on the threaded stud. De-energize or lock out any machine before servicing components in the assembly. Do not overtighten the mounting thread, as this can restrict plunger travel and reduce spring performance. Verify plunger projection clearance against mating components before finalizing the installation.\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\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.186 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: 0.2188 inches\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: 0.9688 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.406 inches\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\u003eLocking Element\u003c\/strong\u003e: Yes\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\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 34026\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51701998518578,"sku":"34026","price":30.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b54792d023b37f3867573c1fe8a2174_8819d96c-d7f0-469c-9f45-aa795327a96c.jpg?v=1788407914","url":"https:\/\/voomisupply.com\/products\/gibraltar-34026-locking-plunger-threaded-stud-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
