It features a 17\/64 inch inside diameter and a 1\/2 inch body outside diameter, with a 3\/8 inch length under the head. The head outside diameter measures 39\/64 inch and the head height is 7\/32 inch. Constructed from steel and hardened to 60 to 65 HRC, the H326HN delivers consistent bore alignment and wear resistance across repeated drilling cycles. It is installed by press fit into a jig plate or fixture body with no additional hardware required.\u003c\/p\u003e\u003cp\u003eThis bushing is intended for use in drill jigs and fixture plates across general metalworking, toolroom, and production machining environments. It suits applications where a permanent, non-renewable bushing is acceptable and precise hole location must be maintained across multiple workpieces. Machinists, toolmakers, and fixture builders install this type of component in both job shop and production floor settings. The headed design provides a positive stop against the jig plate surface, helping to maintain consistent depth and alignment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation — no locking collar or retaining hardware needed\u003c\/li\u003e\n\u003cli\u003eType H headed design provides positive stop against the jig plate surface\u003c\/li\u003e\n\u003cli\u003e17\/64 inch inside diameter with tolerance of +0.0001 to +0.0005 inch for precise tool guidance\u003c\/li\u003e\n\u003cli\u003eSteel construction hardened to 60 to 65 HRC for extended wear life\u003c\/li\u003e\n\u003cli\u003eNon-renewable (fixed) bushing — suited for permanent fixture installations\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards for drill bushing dimensions and tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a permanent press fit replacement or new-installation drill bushing for ANSI-standard Type H headed bushing applications in drill jigs and machining fixtures.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by toolmakers or machinists using an arbor press to seat the bushing flush into a properly sized jig plate bore. The receiving hole in the fixture must be machined to the appropriate press fit tolerance before installation. Once pressed in, this bushing is not intended for removal or replacement. Always verify bore alignment and bushing seating before production drilling begins.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: 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: 17\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/8 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\u003eHardness\u003c\/strong\u003e: 60 to 65 HRC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead or Headless\u003c\/strong\u003e: Head\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\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\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: H326HN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51736312348978,"sku":"H326HN","price":19.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a3df753bfacdecf7a1650e3bb823de6_2e9067a0-538a-4b55-b757-2d3aa54a371b.jpg?v=1788777156","url":"https:\/\/voomisupply.com\/products\/boneham-h326hn-press-fit-headed-drill-bushing-type-h","provider":"Voomi Supply","version":"1.0","type":"link"}
