Manufactured from steel, this bushing features an inside diameter of 0.246 inches with a tight tolerance of +0.0001 to +0.0004 inches, ensuring consistent hole location across repeated operations. The body outside diameter measures 13\/32 inches, the length under head is 1\/2 inch, and the head outside diameter is 1\/2 inch. It is installed by press fitting into a prepared jig plate. Machinists, toolmakers, and fixture builders working in production or job-shop environments are the primary installers of this component.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for use in drill jigs, fixture plates, and tooling setups where accurate, repeatable hole placement is required. The headed design provides a positive stop against the jig plate surface, preventing the bushing from being driven too deep during press installation. It is a fixed, non-renewable bushing, meaning it is intended for permanent installation rather than quick-change applications. Typical use cases include production drilling, reaming guidance, and light boring operations in metalworking environments where maintaining hole location tolerance is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation for permanent, secure seating in jig plates\u003c\/li\u003e\n\u003cli\u003eInside diameter of 0.246 inches with tolerance of +0.0001 to +0.0004 inches for precise tool guidance\u003c\/li\u003e\n\u003cli\u003eHeaded (Type H) design provides a positive stop against the jig plate surface\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability and wear resistance under repeated drilling cycles\u003c\/li\u003e\n\u003cli\u003eNon-renewable fixed bushing design — intended for permanent installation\u003c\/li\u003e\n\u003cli\u003eHead outside diameter of 1\/2 inch and head height of 5\/32 inch for flush seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for drill jig and fixture applications requiring a Type H press fit headed bushing with a 0.246 inch inside diameter and 13\/32 inch body outside diameter per standard bushing industry codes.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by toolmakers or machinist trades using an arbor press or hydraulic press to seat the bushing flush into a properly sized and toleranced jig plate bore. The mating hole in the jig plate must be machined to the appropriate press fit tolerance to ensure secure retention without cracking the surrounding material. Never drive the bushing in with impact tools, as this can deform the bore or damage the bushing head. Verify inside diameter clearance for the intended drill or reamer before pressing the bushing into the fixture.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: Type H Press Fit Headed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.2460 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Letter Code\u003c\/strong\u003e: D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 13\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 5\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead or Headless\u003c\/strong\u003e: Head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRenewable Bushing\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCounterbored\u003c\/strong\u003e: No\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: H268HD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51755305763122,"sku":"H268HD","price":20.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b617461c6c05368cdcf2b33f32fca5ff_d46b8098-56c7-4003-aabd-1098dc451664.jpg?v=1788953384","url":"https:\/\/voomisupply.com\/products\/boneham-h268hd-press-fit-headed-drill-bushing-type-h","provider":"Voomi Supply","version":"1.0","type":"link"}
