This bushing features a 0.339 inch inside diameter, a 9\/16 inch body outside diameter, and a 1\/2 inch overall length. Manufactured from steel and hardened to 60 to 65 HRC, it delivers the wear resistance required for repetitive drilling cycles in production jig and fixture applications. The headless design allows flush mounting in jig plates where a protruding head would interfere with workpiece positioning. Installation is by press fit, requiring no additional fasteners.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jigs, fixture plates, and tooling blocks across general metalworking, manufacturing, and fabrication environments. It is installed by machinists, toolmakers, and jig and fixture builders working in production or job-shop settings. The inside diameter conforms to the Letter size R designation and the Industry Code P bushing standard, making it a direct fit within ANSI-compliant drill bushing tooling systems. The tight inside diameter tolerance of plus 0.0001 to plus 0.0005 inches ensures consistent tool guidance and hole location accuracy across repeated operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation  -  seats directly into jig plate bore without fasteners or retaining collars\u003c\/li\u003e\n  \u003cli\u003eHeadless design allows flush or sub-flush mounting for unobstructed workpiece seating\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for extended wear life in repetitive drilling\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of plus 0.0001 to plus 0.0005 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for drill bushing geometry and dimensional consistency\u003c\/li\u003e\n  \u003cli\u003eNon-renewable fixed bushing  -  intended as a permanent installation in the jig plate\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 for ANSI-standard drill jigs and fixture plates requiring a press fit, headless bushing with a 0.339 inch inside diameter and 9\/16 inch outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePress fit bushings are installed by toolmakers or machinists using an arbor press or hydraulic press  -  never drive with a hammer directly on the bushing face, as this can damage the bore or distort the outer diameter. The receiving bore in the jig plate must be machined to the appropriate interference fit tolerance before installation. Once pressed in, this bushing is not designed for removal and reinstallation. Verify bore alignment and plate thickness against the 1\/2 inch overall length before pressing to final depth.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.3390 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter Size)\u003c\/strong\u003e: R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Wire Code)\u003c\/strong\u003e: P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 1\/2 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\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\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\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\u003eBushing Industry Code\u003c\/strong\u003e: P\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: PT368IZ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51782862733618,"sku":"PT368IZ","price":16.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_64153e7e-e5be-4d1f-a8c0-846fd67045a7.jpg?v=1789182981","url":"https:\/\/voomisupply.com\/products\/boneham-pt368iz-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
