Machined from steel and hardened to 60 to 65 HRC, this bushing resists wear through repeated drilling cycles. The headed design seats flush against the jig plate, keeping the bushing positively located without additional locking hardware. The inside diameter measures 0.1405 inches with a tolerance of plus 0.0001 to plus 0.0004 inches, providing accurate tool guidance consistent with ANSI standards. Machinists, toolmakers, and precision fabricators install this bushing as a permanent, non-renewable component.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for production jigs and fixtures in metalworking, fabrication shops, and manufacturing environments where repeatable hole location is required. The press fit installation method makes it appropriate for applications where the bushing will remain in place for the life of the jig. The 3\/8-inch length under head provides adequate support for standard jig plate thicknesses encountered in typical fixture construction.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType H headed design seats positively against jig plate face\u003c\/li\u003e\n\u003cli\u003ePress fit installation — no locking collar required\u003c\/li\u003e\n\u003cli\u003eInside diameter of 0.1405 inches with tight ANSI tolerance of plus 0.0001 to plus 0.0004 inches\u003c\/li\u003e\n\u003cli\u003eHardened steel construction at 60 to 65 HRC for extended wear life\u003c\/li\u003e\n\u003cli\u003eNon-renewable (permanent) bushing — designed for long-run fixture applications\u003c\/li\u003e\n\u003cli\u003eCompliant with ANSI standards for drill bushings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-install component for standard drill jigs and fixtures requiring a Type H press fit headed drill bushing with a 0.1405-inch bore and 1\/4-inch body outside diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePress fit bushings are installed by toolmakers or machinists using an arbor press — never hammer directly on the bushing head. The jig plate bore must be machined to the appropriate interference fit tolerance before installation. Once pressed in, the bushing is considered permanent and is not designed for removal and replacement. Verify bore alignment with the fixture design before pressing to avoid misalignment that cannot be corrected without scrapping the plate.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.1405 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Wire Gauge)\u003c\/strong\u003e: #28\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: plus 0.0001 to plus 0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 23\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 3\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: Type H (Headed)\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\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: H166EF\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51749615010098,"sku":"H166EF","price":23.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a3df753bfacdecf7a1650e3bb823de6_1d6fe009-c3e2-4acb-ba2c-5ee2c58d1a9c.jpg?v=1788908370","url":"https:\/\/voomisupply.com\/products\/boneham-h166ef-press-fit-headed-drill-bushing-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
