Machined from steel and hardened to 60 to 65 HRC, this bushing delivers consistent bore alignment and long service life in production drilling setups. The inside diameter is 0.043 inches (wire size No. 57) with a tolerance of +0.0001 to +0.0004 inches, providing tight control over drill positioning. The headed design seats flush against the jig plate face, resisting axial displacement under cutting forces. Machinists, toolmakers, and production engineers install this component during jig and fixture assembly or tooling maintenance.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jigs and fixture plates where a permanent, non-renewable guide bushing is required. The press fit installation method locks the bushing in place without additional fasteners. With a body outside diameter of 5\/32 inches, a length under head of 1\/4 inches, a head outside diameter of 1\/4 inches, and a head height of 3\/32 inches, this component fits standard jig plate bores machined to ANSI specifications. It is appropriate for both prototype tooling and high-volume production environments where repeatable hole location is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation — no retaining ring or locking collar required\u003c\/li\u003e\n  \u003cli\u003eHeaded design resists axial pullout during drilling operations\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.043 inches (No. 57 wire size) with +0.0001 to +0.0004 inch tolerance\u003c\/li\u003e\n  \u003cli\u003eHardened steel construction at 60 to 65 HRC for wear resistance\u003c\/li\u003e\n  \u003cli\u003ePermanent (non-renewable) bushing — ideal for fixed production tooling\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI standards for drill bushing dimensions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a permanent OEM-style press fit headed drill bushing for use in drill jig plates and fixture bodies machined to ANSI Type H bushing bore specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by toolmakers or machinist technicians using an arbor press or drill bushing press tool. The receiving bore in the jig plate must be machined to the appropriate ANSI interference fit tolerance before installation. Press the bushing in squarely to avoid bore damage or misalignment. Once installed, this is a permanent bushing and is not intended to be removed and replaced during normal service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: Type H (Headed Press Fit)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.043 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Wire Size)\u003c\/strong\u003e: No. 57\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: 5\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 3\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 60 to 65 HRC\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\u003eStandards\u003c\/strong\u003e: ANSI\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: BONEHAM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: H104BB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51753845293362,"sku":"H104BB","price":60.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a3df753bfacdecf7a1650e3bb823de6_8e53a9f1-82b7-41a1-bf63-a7e98b7b015f.jpg?v=1788941425","url":"https:\/\/voomisupply.com\/products\/boneham-h104bb-press-fit-headed-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
