It features a 3\/16 inch (0.1875 inch) inside diameter with a tight tolerance of +0.0001 to +0.0004 inches, a 1\/2 inch body outside diameter, and a 1\/4 inch length under the head. The headed design includes a 39\/64 inch head outside diameter and a 7\/32 inch head height, providing a positive stop against the drill jig plate surface. Constructed from steel, this bushing is suited for fixed-installation jig tooling where a non-renewable bushing is acceptable. Machinists, tool and die makers, and production drilling setups are the primary users.\u003c\/p\u003e\u003cp\u003eThis bushing is used in drill jig fixtures in manufacturing, metalworking, and precision machining environments. Press fit installation means the bushing is driven or pressed directly into a mating hole in the jig plate and is intended to remain permanently in place. It is appropriate for production runs where tool guidance consistency is critical and bushing replacement is not required between cycles. The Type H designation follows industry standard bushing codes used across jig and fixture tooling applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/16 inch inside diameter with +0.0001 to +0.0004 inch tolerance for precise tool guidance\u003c\/li\u003e\n\u003cli\u003ePress fit installation for permanent, fixed positioning in drill jig plates\u003c\/li\u003e\n\u003cli\u003eHeaded design with 39\/64 inch head OD provides positive seating against jig surface\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in production drilling applications\u003c\/li\u003e\n\u003cli\u003eNon-renewable bushing — designed for permanent installation, not field replacement\u003c\/li\u003e\n\u003cli\u003eConforms to Type H industry bushing standard for drop-in jig fixture compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a permanent press fit replacement or new-installation Type H headed drill bushing for steel drill jig plates requiring a 3\/16 inch bore guide with a 1\/2 inch body outside diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or tool room personnel using an arbor press or hydraulic press sized for the bushing body diameter. The mating jig plate bore must be machined to the correct press fit tolerance before installation to achieve proper retention. Once pressed in, the bushing is not designed to be removed without damage to the surrounding material. Verify bore alignment and jig plate thickness before pressing to ensure the head seats flush against the plate surface.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0004 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 39\/64 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 7\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: Type H (Headed, Press Fit)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRenewable\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCounterbored\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BONEHAM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: H324FT\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51729508794674,"sku":"H324FT","price":17.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b617461c6c05368cdcf2b33f32fca5ff_091f15bf-cfe4-405d-b98e-3a570993fa8b.jpg?v=1788705428","url":"https:\/\/voomisupply.com\/products\/boneham-h324ft-press-fit-headed-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
