Built to Industry Code P, this bushing features a 0.257 inch inside diameter (Letter F), a 7\/16 inch body outside diameter, and a 3\/4 inch overall length. Manufactured from hardened steel with a Rockwell hardness of 60 to 65 HRC, it provides consistent bore guidance and long service life under repeated drilling cycles. The headless design allows flush seating in close-clearance fixture plates. Inside diameter tolerance is held to +0.0001 to +0.0005 inches, meeting ANSI standards for drill bushing accuracy.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for use in production drilling fixtures, jigs, and tooling plates where a permanent, non-renewable press fit installation is required. Typical applications include metal fabrication shops, machine shops, and tooling departments where repeatable hole location accuracy is critical. The press fit installation method locks the bushing directly into a prepared receiver hole without the need for a locking collar or retaining screw, making it a clean solution for high-cycle tooling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIndustry Code P headless press fit design for permanent fixture installation\u003c\/li\u003e\n\u003cli\u003e0.257 inch ID (Letter F) with tight tolerance of +0.0001 to +0.0005 inches for precise drill guidance\u003c\/li\u003e\n\u003cli\u003e7\/16 inch body outside diameter and 3\/4 inch overall length\u003c\/li\u003e\n\u003cli\u003eHardened steel construction, 60 to 65 HRC for wear resistance\u003c\/li\u003e\n\u003cli\u003eComplies with ANSI drill bushing standards\u003c\/li\u003e\n\u003cli\u003eNon-renewable design for fixed, long-term tooling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct tooling component for drill jigs and fixtures requiring an ANSI-standard Industry Code P press fit headless bushing with a 0.257 inch bore.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePress fit bushings are installed by machinists or tooling technicians using an arbor press or hydraulic press fitted with an appropriate driver. The receiver hole in the fixture plate must be machined to the correct interference fit diameter per ANSI specifications before installation. Never hammer the bushing in directly without a driver to avoid distorting the bore. Confirm ID integrity with a plug gauge after pressing to verify dimensional accuracy was maintained.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.257 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter)\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: 7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Headless\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\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: PT2812HJ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51738371785010,"sku":"PT2812HJ","price":17.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_c9fe834d-db98-474f-8726-28ef2be87fbd.jpg?v=1788798753","url":"https:\/\/voomisupply.com\/products\/boneham-pt2812hj-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
