Manufactured from steel with a hardness rating of 60 to 65 HRC, this bushing holds tight tolerances for consistent hole location and repeatability. The inside diameter measures 0.257 inches with a tolerance of +0.0001 to +0.0005 inches, and the body outside diameter is 0.5 inches. Overall bushing length is also 0.5 inches. The headless design allows the bushing to sit flush within a jig plate without a protruding flange, making it well suited for close-tolerance tooling fixtures. Machinists and tool and die makers install this component in production and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bushing is intended for use in drill jigs and fixture plates where repeatable hole guidance is required. The press fit installation method means the bushing is driven directly into a prepared hole in the jig body without the need for a locking mechanism or retaining screw. It is a permanent-style bushing, not renewable or interchangeable. Industry bushing code P and inside diameter letter designation F apply, making this part identifiable within standard ANSI drill bushing sizing charts. Typical applications include metalworking production lines, custom fixturing, and maintenance repair operations requiring accurate hole guidance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation — no locking collar or retainer required\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush with jig plate surface\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for wear resistance\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0005 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI standards for drill bushing dimensions and tolerances\u003c\/li\u003e\n  \u003cli\u003eNon-renewable fixed bushing suitable for permanent fixture installations\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 bushing conforming to ANSI press fit headless bushing standards, suitable for drill jigs and fixture plates requiring a 0.257-inch ID and 0.5-inch OD bushing.\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 similar press equipment to drive the bushing into a properly reamed jig plate bore. The receiving hole must be prepared to the correct interference fit tolerance before pressing the bushing into place. Never hammer the bushing directly without a proper driver to avoid distorting the bore. Once pressed in, this bushing is not designed for removal and reinstallation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal Inch)\u003c\/strong\u003e: 0.2570 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Letter Designation\u003c\/strong\u003e: F\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: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Headless\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: P\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\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: P328HJ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51747791634738,"sku":"P328HJ","price":16.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_bcef0fd6-a902-4ffb-b5ee-e1daf7b1da93.jpg?v=1788885523","url":"https:\/\/voomisupply.com\/products\/boneham-p328hj-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
