With an inside diameter of 0.238 inches and a body outside diameter of 7\/16 inches, this bushing provides accurate bore alignment during repetitive drilling operations. The overall length of 3\/8 inches makes it suited for shallow jig plates where a low-profile bushing is required. It is classified under industry code P and is installed by pressing directly into a prepared hole in a drill jig, fixture plate, or tooling body without the use of a retaining head flange.\u003c\/p\u003e\u003cp\u003eThis bushing is intended for use in precision metalworking, machining, and fabrication environments where consistent hole location is critical. It is a non-renewable type, meaning it is pressed permanently into the jig plate and is not designed for quick field replacement. Machinists, toolmakers, and fixture builders working in production or prototype environments will find this bushing appropriate for applications requiring tight bore guidance and repeatable part positioning across high-cycle drilling runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation method — no set screw or locking collar required\u003c\/li\u003e\n\u003cli\u003eHeadless design allows flush or sub-flush seating in jig plates\u003c\/li\u003e\n\u003cli\u003eInside diameter tolerance of plus 0.0001 to plus 0.0004 inches for precise drill guidance\u003c\/li\u003e\n\u003cli\u003eSteel construction provides durability in production drilling applications\u003c\/li\u003e\n\u003cli\u003eIndustry code P classification for standard drill bushing identification\u003c\/li\u003e\n\u003cli\u003eNon-renewable fixed installation for permanent fixture setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard P-series press fit headless drill bushing for use in precision machined jig plates and fixture tooling where a 7\/16-inch outside diameter press fit bore has been prepared.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a toolmaker or machinist using an arbor press or hydraulic press to seat the bushing flush into a pre-bored jig plate hole sized to the bushing outside diameter tolerance. Ensure the receiving bore is clean and free of burrs before pressing to avoid bushing distortion. Because this is a non-renewable bushing, removal will likely damage the bushing and may require reaming or boring of the jig plate for replacement. Follow applicable shop safety procedures and de-energize any powered fixtures before servicing tooling components.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal Inch)\u003c\/strong\u003e: 0.2380 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter)\u003c\/strong\u003e: B\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: 7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Headless\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Material\u003c\/strong\u003e: Steel\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\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: PT286GZ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51730071617842,"sku":"PT286GZ","price":16.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce78178c931fa10e96a1ac736c6a2c2c.jpg?v=1788711232","url":"https:\/\/voomisupply.com\/products\/boneham-pt286gz-press-fit-headless-drill-bushing-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
