It features a 3\/8-16 thread size with a 1.2-inch thread length, a plunger diameter of 0.233 inches, and a plunger projection of 0.375 inches. The integrated locking element holds the plunger in the retracted position until manually released via the pull ring, which measures 0.98 inches in diameter. End force ranges from 2 pounds initial to 4 pounds final, making it suitable for light-duty positive-stop and detent applications. Machinists, millwrights, and mechanical assembly technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis plunger is used in industrial equipment, jigs, fixtures, enclosures, and machine tool assemblies where a retractable, lockable locating pin is required. The locking pull ring allows the plunger to remain retracted without continuous manual force, which is useful in repetitive alignment or access-panel applications. With a body length of 1.68 inches and a head height of 0.48 inches, it fits into compact threaded boss locations common in light industrial and OEM equipment builds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLocking element holds plunger in retracted position until released by pull ring\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 thread size with 1.2-inch thread length for standard threaded boss installation\u003c\/li\u003e\n  \u003cli\u003e0.233-inch plunger diameter with 0.375-inch projection for positive-stop detent engagement\u003c\/li\u003e\n  \u003cli\u003e2-pound initial to 4-pound final end force for light-duty indexing and positioning\u003c\/li\u003e\n  \u003cli\u003eStainless steel construction for corrosion resistance in washdown or outdoor-adjacent environments\u003c\/li\u003e\n  \u003cli\u003ePull ring diameter of 0.98 inches provides accessible grip in tight assembly locations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation locking pull ring plunger for threaded assemblies requiring a 3\/8-16 threaded boss and a retractable locking plunger mechanism.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the plunger body into a prepared 3\/8-16 tapped hole to the required depth, then securing with a jam nut or thread-locking compound as appropriate for the application. De-energize or lock out any powered equipment before servicing assemblies containing this plunger. Use appropriate thread engagement depth to avoid bottoming out the plunger body, which would prevent proper spring function. Verify plunger projection and clearance against mating locating holes before final assembly.\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: 1.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Diameter\u003c\/strong\u003e: 0.233 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Projection\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial End Force\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinal End Force\u003c\/strong\u003e: 4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Length\u003c\/strong\u003e: 1.68 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1.68 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.48 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Diameter\u003c\/strong\u003e: 0.98 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlunger Type\u003c\/strong\u003e: Locking\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: Stainless Steel\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: SSTPR38-PT-G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":67906458517810,"sku":"SSTPR38-PT-G","price":28.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1afd6b7a445be6d79bc40346df29b4e1.jpg?v=1791168398","url":"https:\/\/voomisupply.com\/products\/gibraltar-sstpr38-pt-g-locking-pull-ring-plunger-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
