Configured with a 3\/8-16 thread size and a 3\/4 inch thread length, this plunger delivers an initial end force of 1.5 pounds and a final end force of 8 pounds. The maximum plunger diameter is 0.216 inches with a tolerance of plus 0.001 inches, and the plunger projection measures 7\/32 inches (0.2188 inches). Constructed from steel with a zinc-plated finish, it is designed for durability in environments where corrosion resistance and repeatable locking action are required. Mechanical technicians and machine builders are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis plunger is suited for use in jigs, fixtures, machine tools, and equipment panels where a locking index point is needed. The threaded stud mount (5\/16-18 stud thread size) allows for straightforward installation into tapped holes or mounting plates. With a plunger length of 1.691 inches and a length under head\/shoulder of 31\/32 inches (0.9688 inches), it fits common panel thickness ranges found in light industrial and OEM equipment assemblies. The knobless threaded stud style makes it appropriate for applications where a low-profile or tool-actuated interface is preferred over a hand-knob design.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLocking plunger with built-in locking element for positive hold at indexed positions\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 external thread with 3\/4 inch thread length for secure panel mounting\u003c\/li\u003e\n  \u003cli\u003eKnobless threaded stud (5\/16-18) configuration for low-profile or recessed installation\u003c\/li\u003e\n  \u003cli\u003eInitial end force of 1.5 pounds, final end force of 8 pounds for consistent indexing force\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc-plated finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eTight plunger diameter tolerance of plus 0.001 inches for precision fitment\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 industrial fixtures, jigs, machine panels, and equipment assemblies requiring a 3\/8-16 locking index plunger with a knobless threaded stud mount.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by mechanical technicians or machine builders. Power down or de-energize any associated equipment before servicing or replacing index plungers in a panel or fixture assembly. Ensure the receiving tapped hole matches the 3\/8-16 thread specification before installation. Do not exceed the rated end force by applying external impact or excessive loading to the plunger shaft.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eMaximum Plunger Diameter\u003c\/strong\u003e: 0.216 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: 0.2188 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: 13\/32 inches\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\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\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\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: 34238\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51723429544242,"sku":"34238","price":40.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b64298da9ea69ad87dd83f6a4eb77211.jpg?v=1788604780","url":"https:\/\/voomisupply.com\/products\/gibraltar-34238-locking-plunger-3-8-16-3-4-inch-thread","provider":"Voomi Supply","version":"1.0","type":"link"}
