With an inside diameter of 55\/64 inches and a body outside diameter of 1-3\/8 inches, this bushing is pressed directly into a drill jig plate and held in place without a locking collar. The head sits flush against the top surface of the jig plate, providing a positive stop and consistent tool guidance. The length under the head measures 1\/2 inch. This part is a non-renewable bushing, meaning it is pressed in permanently for fixed tooling setups.\u003c\/p\u003e\n\u003cp\u003eThe H888NU is used in metalworking, machining, and fabrication environments where repeatable hole placement is required. It fits into drill jig fixtures used in production and job-shop settings for ferrous and non-ferrous materials. The headed design keeps the bushing seated under axial load from drilling operations. Licensed machinists and toolmakers typically install and replace these bushings as part of fixture building or maintenance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType H press fit headed bushing — no locking collar required\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production drilling environments\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0002 to +0.0006 inches for consistent tool guidance\u003c\/li\u003e\n  \u003cli\u003eHeaded design provides a positive stop against the jig plate surface\u003c\/li\u003e\n  \u003cli\u003eNon-renewable design — permanently pressed into fixture for fixed tooling setups\u003c\/li\u003e\n  \u003cli\u003eNot counterbored — standard through-bore configuration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation drill jig bushing conforming to Type H headed press fit bushing standards, suitable for use in standard drill jig plates with a corresponding press fit bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or tool and die makers using an arbor press or hydraulic press to seat the bushing flush into the jig plate bore. Ensure the receiving bore in the fixture plate is machined to the correct press fit tolerance before installation. Once pressed in, this bushing is not intended for removal and reinstallation. Always verify inside diameter clearance matches the intended drill or tool shank before pressing the bushing into the plate.\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\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\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 3\/8 inch\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\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\u003eUNSPSC Code\u003c\/strong\u003e: 31171603\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: H888NU\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51749312528690,"sku":"H888NU","price":31.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b0951bcd7cd87512be7668536acda84.jpg?v=1788904406","url":"https:\/\/voomisupply.com\/products\/boneham-h888nu-press-fit-headed-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
