It features a 9\/64-inch inside diameter and a 5\/16-inch body outside diameter, with a 1\/4-inch length under the head. Machined from steel, this bushing is pressed directly into a drill jig plate and held in place by its head, which measures 27\/64 inches in outside diameter and 1\/8 inch in height. It is not renewable and is intended as a fixed, permanent installation. Machinists, toolmakers, and precision fabricators use this bushing to maintain consistent hole location across repeated drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jigs, fixtures, and workholding setups where repeatable hole placement is required. It is commonly installed in production environments, machine shops, and toolrooms. The Type H designation indicates a headed style with a press fit installation method, making it appropriate for applications where the bushing must remain stationary under drilling load and lateral force. The inside diameter tolerance of +0.0001 to +0.0004 inches supports close-clearance drill guidance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType H headed design seats flush against the jig plate surface to resist axial movement during drilling\u003c\/li\u003e\n  \u003cli\u003ePress fit installation — no locking screws or additional hardware required\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0004 inches for precise drill guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability under repeated drilling cycles\u003c\/li\u003e\n  \u003cli\u003eNon-renewable fixed bushing design for permanent jig setups\u003c\/li\u003e\n  \u003cli\u003eHead outside diameter of 27\/64 inches and head height of 1\/8 inch provide positive retention against pull-through\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct installation bushing for drill jigs and fixtures requiring a Type H press fit headed bushing with a 9\/64-inch bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by toolmakers or machinists using a press or arbor press to drive the bushing into a correctly sized counterbored or straight hole in the jig plate. The receiving hole must be machined to the appropriate interference fit tolerance to ensure secure retention. Do not hammer the bushing in directly without a driver or press adapter, as this can damage the head or distort the bore. Verify bore alignment before pressing to final depth.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 9\/64 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: 5\/16 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\u003eHead Outside Diameter\u003c\/strong\u003e: 27\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead or Headless\u003c\/strong\u003e: Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\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\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: H204EG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51749322948914,"sku":"H204EG","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b617461c6c05368cdcf2b33f32fca5ff_4cb8b060-5e34-40b4-9d6c-c612d1c98f62.jpg?v=1788904529","url":"https:\/\/voomisupply.com\/products\/boneham-h204eg-press-fit-headed-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
