Manufactured from steel, this bushing installs permanently into a drill jig plate without a locking mechanism, relying on an interference press fit for retention. The inside diameter measures 55\/64 inches with a close tolerance of +0.0002 to +0.0006 inches, ensuring accurate tool guidance. The body outside diameter is 1-3\/8 inches, and the length under the head is 1 inch. Machinists, toolmakers, and fixture builders install this component during jig fabrication or repair.\u003c\/p\u003e\n\u003cp\u003eThis drill bushing is suited for use in production and maintenance machining environments where a fixed, non-renewable guide bushing is required. It is pressed directly into the jig plate bore and is intended to remain in place for the life of the tooling. The headed design provides a positive stop against the jig plate surface, controlling seating depth. Applications include drilling, reaming, and countersinking operations in metal fabrication, aerospace, automotive, and general manufacturing settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation — no locking collar or liner bushing required\u003c\/li\u003e\n  \u003cli\u003eType H headed design provides a positive seating stop against the jig plate\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0002 to +0.0006 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in high-cycle drilling applications\u003c\/li\u003e\n  \u003cli\u003eNon-renewable design — intended for permanent installation in the fixture\u003c\/li\u003e\n  \u003cli\u003eHead outside diameter of 1-39\/64 inches and head height of 3\/8 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or original-build component for drill jigs and fixtures requiring a Type H press fit headed bushing with a 55\/64-inch inside diameter and 1-3\/8-inch body outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by toolmakers or machinists using an arbor press or hydraulic press to drive the bushing into a precision-bored jig plate hole. The bore in the jig plate must be machined to the correct interference fit tolerance before installation. Once pressed in, the bushing is not designed for removal or replacement. Always verify bore diameter and surface finish before pressing to avoid damaging the bushing or jig plate.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: 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\u003c\/strong\u003e: 55\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0002 to +0.0006 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 1-39\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Headed\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\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: H8816NU\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51746657403186,"sku":"H8816NU","price":31.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b617461c6c05368cdcf2b33f32fca5ff_edc6d5d8-ac37-4b53-9a5f-289fafbed1ce.jpg?v=1788872255","url":"https:\/\/voomisupply.com\/products\/boneham-h8816nu-press-fit-headed-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
