With an inside diameter of 0.358 inches and a body outside diameter of 0.75 inches, this bushing installs directly into a jig plate without the need for a locking collar or head flange. The overall length is 0.375 inches. Manufactured from steel, the P486JH provides the hardness and wear resistance required for repeated drilling cycles in production and job-shop environments. It carries industry code P and is installed by machinists, tool-and-die makers, and precision fabricators.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jigs and fixture plates where a flush, headless profile is required. The press fit installation method means the bushing is driven or pressed into a reamed hole in the jig body and held in place by interference fit alone. It is not renewable and is intended as a permanent installation. Typical applications include precision hole location in metal fabrication, assembly fixtures, and production drilling setups where consistent hole placement across multiple workpieces is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHeadless design sits flush with the jig plate surface for unobstructed tool travel\u003c\/li\u003e\n  \u003cli\u003ePress fit installation method — no locking collar required\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.358 inches with a close tolerance of +0.0001 to +0.0005 inches for accurate tool guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides hardness and wear resistance for high-cycle drilling operations\u003c\/li\u003e\n  \u003cli\u003eIndustry code P for straightforward cross-reference with standard drill bushing catalogs\u003c\/li\u003e\n  \u003cli\u003eCompact 0.375 inch overall length suits thin jig plates and space-constrained fixtures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for standard P-series press fit headless drill bushing applications in drill jigs and fixture plates conforming to industry code P dimensions.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolmakers using a drill bushing press or arbor press to drive the bushing into a precision-reamed hole sized for the appropriate interference fit. Ensure the jig plate hole is reamed to the correct tolerance before pressing the bushing in place, as the P486JH is a non-renewable bushing and is not designed for removal after installation. Always deburr the receiving hole before installation to avoid damage to the bushing or jig plate. Follow applicable shop safety procedures when operating pressing equipment.\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: 0.358 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter)\u003c\/strong\u003e: T\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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: P\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 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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171603\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: P486JH\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51734279094578,"sku":"P486JH","price":20.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c0ae6f57edf2d34f7aecb6dd395f13ca.jpg?v=1788762200","url":"https:\/\/voomisupply.com\/products\/boneham-p486jh-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
