The pin features a 3\/8-inch diameter and a 3.5-inch usable length, making it suitable for moderate-load positioning and alignment applications. Constructed from 4130 alloy steel with a zinc-plated finish, it offers solid strength-to-weight performance and basic corrosion resistance for shop and field use. Machinists, fabricators, maintenance technicians, and equipment assemblers commonly install this type of pin where repeatable, hand-operated connect and disconnect cycles are required.\u003c\/p\u003e\u003cp\u003eThe LBT-139 fits applications in manufacturing fixtures, material handling equipment, agricultural machinery, and general industrial assemblies where a standard 3\/8-inch bore is present. The T-handle provides a positive grip surface for quick actuation without tools, reducing downtime during setup changes, tooling swaps, or equipment reconfiguration. It is sold as a single unit and is measured in the inch system of measurement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-inch pin diameter for standard bore fitment\u003c\/li\u003e\n\u003cli\u003e3.5-inch usable length accommodates typical clevis and bracket thicknesses\u003c\/li\u003e\n\u003cli\u003e4130 alloy steel construction for reliable tensile strength in mechanical applications\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish provides basic corrosion resistance in shop and light outdoor environments\u003c\/li\u003e\n\u003cli\u003eT-handle design enables tool-free, single-hand operation\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.175 pounds for frequent hand-cycling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-geometry quick-release pin for use in any mechanical assembly or fixture with a 3\/8-inch diameter bore requiring tool-free pin retention.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires no special tools — align the pin with the bore, insert fully until the release mechanism seats, and confirm positive retention before applying load. Always verify that the pin diameter and usable length match the bore depth and bracket thickness before installation. De-energize or lock out any powered or spring-loaded equipment before inserting or removing the pin. Inspect the pin and bore for wear or deformation at regular service intervals.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Type\u003c\/strong\u003e: Quick-Release\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: T-Handle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsable Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Material\u003c\/strong\u003e: 4130 Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 0.58 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 2.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 5.32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.175 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31162400\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: LBT-139\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51715584393522,"sku":"LBT-139","price":32.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bd087d9eb8e8c06dee76205ff82f4720_31a804a4-ba7f-47e6-8e19-bc1a8fb5d821.jpg?v=1788515949","url":"https:\/\/voomisupply.com\/products\/gibraltar-lbt-139-quick-release-t-handle-pin-3-8-in-4130-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
