It features a 23\/32-inch inside diameter, a 1-inch body outside diameter, and a 3\/4-inch length under the head. Constructed from steel and hardened to 60 to 65 HRC, this bushing delivers the wear resistance and dimensional stability required for accurate, repeatable hole locations in jig and fixture applications. The head outside diameter measures 1-15\/64 inches with a head height of 5\/16 inches. Machinists, tool and die makers, and fixture builders install this bushing in drilling jigs where a permanent, non-renewable guide is specified.\u003c\/p\u003e\u003cp\u003eThe H6412MX is suited for production and prototype drilling fixtures across metalworking and manufacturing environments. Its press fit installation method secures the bushing directly into the jig plate without a liner bushing, making it appropriate for high-volume applications where the bushing position does not require routine replacement. The inside diameter tolerance of plus 0.0001 to plus 0.0005 inches ensures consistent tool guidance and repeatable hole placement across production runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType H headed design provides a positive stop against the jig plate surface during installation\u003c\/li\u003e\n\u003cli\u003e23\/32-inch inside diameter with a tolerance of plus 0.0001 to plus 0.0005 inches for precise tool guidance\u003c\/li\u003e\n\u003cli\u003eHardened steel construction at 60 to 65 HRC for extended wear life in high-cycle drilling applications\u003c\/li\u003e\n\u003cli\u003ePress fit installation method — no liner bushing required\u003c\/li\u003e\n\u003cli\u003eNon-renewable design optimized 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 an OEM-style replacement or direct installation component for drilling jigs and fixtures requiring a Type H press fit headed drill bushing per ANSI standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePress fit bushings are typically installed by toolmakers or machinists using an arbor press to drive the bushing flush or to the head seat in the jig plate. Power down all machinery before bushing installation or removal. The bore receiving the bushing must be machined to the correct press fit tolerance to ensure proper retention and concentricity. Consult applicable ANSI jig bushing standards and shop engineering requirements before finalizing fixture design.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: Type H 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: 23\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: plus 0.0001 to plus 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 1-15\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 5\/16 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\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\u003eStandards\u003c\/strong\u003e: ANSI\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: H6412MX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51728553083186,"sku":"H6412MX","price":22.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a3df753bfacdecf7a1650e3bb823de6_0e770591-3e0c-49f9-bd51-ebedbd9ee09e.jpg?v=1788693204","url":"https:\/\/voomisupply.com\/products\/boneham-h6412mx-press-fit-headed-drill-bushing-type-h","provider":"Voomi Supply","version":"1.0","type":"link"}
