Manufactured from steel, this bushing features a 35\/64 inch inside diameter and a 7\/8 inch body outside diameter, sized to seat firmly in a jig plate without the need for locking hardware. The head sits proud of the jig surface to locate the bushing axially and prevent migration under load. Machinists, toolmakers, and jig-and-fixture builders install this component as part of drill jig assemblies in production and maintenance machine shop environments.\u003c\/p\u003e\n\u003cp\u003eThe H5612LU is suited for fixed-location tooling applications where the bushing remains in place for the life of the jig. It is not a renewable-style bushing, making it appropriate for single-tool operations or dedicated fixtures where tool changes at the bushing position are not required. Typical installations occur in steel or cast-iron jig plates used in metal fabrication, aerospace component drilling, and general precision machining setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType H headed design provides positive axial stop against the jig plate surface\u003c\/li\u003e\n  \u003cli\u003ePress fit installation method eliminates need for retaining screws or locking collars\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of plus 0.0001 to plus 0.0005 inches ensures close-clearance tool guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction delivers durability under repeated tool cycling\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch length under head provides adequate guidance depth for standard jig plate thicknesses\u003c\/li\u003e\n  \u003cli\u003eNon-renewable design for permanent, single-tool jig configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a permanent press fit replacement or new-build component for Type H headed drill jig bushing applications requiring a 35\/64 inch inside diameter, 7\/8 inch body outside diameter, and 3\/4 inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by toolmakers or machinists using an arbor press to drive the bushing into a properly sized and toleranced hole in the jig plate. Power down all associated machinery before pressing the bushing into position. Do not hammer the bushing directly without a driver or press fixture, as this can deform the head or misalign the bore. Confirm the receiving hole dimensions meet the required press fit tolerances before installation, as the bushing is not removable without damaging the jig plate bore.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: 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: 35\/64 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: 7\/8 inches\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: 1-7\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1\/4 inches\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  \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: H5612LU\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51738224853298,"sku":"H5612LU","price":22.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9d1291cf40ec0aba8857fbbbb7d41c9e.jpg?v=1788796967","url":"https:\/\/voomisupply.com\/products\/boneham-h5612lu-press-fit-headed-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
