With an inside diameter of 0.242 inches (Letter C) and an inside diameter tolerance of +0.0001 to +0.0004 inches, this bushing delivers tight positional accuracy for production drilling operations. The 1\/2-inch body outside diameter and 1\/4-inch length under head suit a range of standard jig plate thicknesses. Machinists, tool and die makers, and fixture builders install this type of bushing in drill jigs to maintain consistent hole location across repeat parts.\u003c\/p\u003e\u003cp\u003eThe H324HB is suited for use in drill jigs, assembly fixtures, and tooling plates in both job shop and production environments. The headed design seats flush against the jig plate surface, resisting axial displacement under drilling pressure. The press fit installation method locks the bushing permanently into the jig plate without additional fasteners, making it appropriate for fixed, non-renewable tooling setups where the bushing does not need field replacement between operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType H headed design seats against jig plate surface to resist axial pullout during drilling\u003c\/li\u003e\n\u003cli\u003ePress fit installation method provides a permanent, fastener-free lock in the jig plate bore\u003c\/li\u003e\n\u003cli\u003eInside diameter tolerance of +0.0001 to +0.0004 inches ensures precise drill guidance and repeatable hole location\u003c\/li\u003e\n\u003cli\u003eSteel construction provides hardness and wear resistance for production drilling cycles\u003c\/li\u003e\n\u003cli\u003eNon-renewable fixed bushing configuration suitable for dedicated, single-operation tooling setups\u003c\/li\u003e\n\u003cli\u003eHead outside diameter of 39\/64 inches and head height of 7\/32 inches for positive seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or original-fit press fit headed drill bushing for standard drill jig and fixture plates requiring a Type H bushing with a 0.242-inch inside diameter and 1\/2-inch body outside diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePress fit drill bushings are installed by toolmakers and machinists using an arbor press or hydraulic press; do not drive with a hammer, as uneven force can distort the bushing bore or damage the jig plate. Ensure the receiving bore in the jig plate is machined to the correct press fit tolerance before installation, as this bushing is non-renewable and is not intended for removal after seating. Verify bore alignment before pressing to avoid cocking the bushing in the plate.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: H (Headed Press Fit)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter)\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.242 inches\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: 0.5 inches (1\/2 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.25 inches (1\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 39\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 7\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: H324HB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51745944371506,"sku":"H324HB","price":18.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b617461c6c05368cdcf2b33f32fca5ff_85915fcb-d7fc-4ad5-aff2-13e8fb7842b1.jpg?v=1788865838","url":"https:\/\/voomisupply.com\/products\/boneham-h324hb-press-fit-headed-drill-bushing-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
