Assigned industry bushing code P, this part features an inside diameter of 0.246 inches (Letter D) with a tight tolerance of plus 0.0001 to plus 0.0004 inches, a body outside diameter of 7\/16 inches, and an overall length of 5\/16 inches. Manufactured from steel, the PT285HD is a fixed, non-renewable bushing intended for permanent installation in jig plates and drill fixtures. Machinists, toolmakers, and fixture builders working in precision machining environments are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jigs, fixture tooling, and production setups where consistent hole location and tool guidance are required across repeated operations. The headless design allows the bushing to sit flush within the jig plate, making it appropriate for applications where clearance above the work surface is limited or where a smooth, unobstructed fixture face is needed. It is a standard catalog size conforming to common jig bushing industry dimensions, and fits tooling setups calling for a P-series headless press fit bushing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation method for permanent, fixed positioning in drill jigs\u003c\/li\u003e\n  \u003cli\u003eHeadless design allows flush mounting within the jig plate surface\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of plus 0.0001 to plus 0.0004 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003e0.246 inches inside diameter (Letter D, industry bushing code P)\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production drilling environments\u003c\/li\u003e\n  \u003cli\u003eNon-renewable fixed bushing — intended for permanent installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install component for drill jig fixtures and tooling plates requiring a P-series headless press fit bushing with a 0.246 inches inside diameter and 7\/16 inches outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by toolmakers or machinist-level trades using an arbor press or hydraulic press to seat the bushing flush into a precision-reamed hole in the jig plate. The receiving bore in the jig plate must be machined to the appropriate interference fit specification to ensure the bushing is retained securely without rotation or pullout. Do not drive the bushing with a hammer directly on the bore face, as this can distort the inside diameter and compromise tool guidance accuracy. Because this is a non-renewable bushing, replacement requires pressing out the worn part and restoring the jig plate bore before pressing in the new bushing.\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: 0.2460 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter)\u003c\/strong\u003e: D\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: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: P\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\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: PT285HD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51748792369458,"sku":"PT285HD","price":19.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cbdb03352bdb6f7724e4733f8ed2a679.jpg?v=1788898449","url":"https:\/\/voomisupply.com\/products\/boneham-pt285hd-press-fit-headless-drill-bushing-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
