Carrying industry code P, this bushing features a 0.404 inch inside diameter (Letter size Y, Decimal 0.4040 inches) and a 3\/4 inch body outside diameter. The inside diameter is held to a tight tolerance of +0.0001 to +0.0005 inches, ensuring accurate and repeatable hole location across production runs. Constructed from steel, it is pressed directly into a drill jig plate without a locking head, keeping the top surface flush for workpiece clearance. Machinists, tool and die makers, and fixture builders are the primary installers of this component.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for use in drill jigs, production fixtures, and precision machining setups where consistent hole guidance is required. The headless design is preferred when a flush or near-flush bushing surface is needed and no tool-free removal is required. The press fit installation method means the bushing is permanently seated in the jig plate under interference fit conditions. It is not a renewable bushing, making it appropriate for long-run fixtures where the bushing is not expected to be field-swapped during normal production.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIndustry code P headless press fit bushing for permanent jig plate installation\u003c\/li\u003e\n\u003cli\u003eInside diameter of 0.4040 inches (Letter size Y) with tight tolerance of +0.0001 to +0.0005 inches\u003c\/li\u003e\n\u003cli\u003e3\/4 inch body outside diameter for a secure interference fit in standard jig plate bores\u003c\/li\u003e\n\u003cli\u003e1 inch overall bushing length provides adequate drill guidance depth\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in repetitive drilling operations\u003c\/li\u003e\n\u003cli\u003eNon-renewable design suited for fixed, long-term fixture use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation drill bushing for use in standard drill jig fixtures requiring a P-series headless press fit bushing with a 0.404 inch inside diameter and 3\/4 inch outside diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePress fit bushings are typically installed by tool and die makers or machinist-level trades using an arbor press to avoid cocking or damage to the bushing bore. The receiving hole in the jig plate must be machined to the correct tolerance to achieve the proper interference fit. Do not drive the bushing in with impact tools, as this can distort the inside diameter and degrade hole location accuracy. Verify inside diameter after installation if tolerances are critical to the application.\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: 0.4040 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter Size)\u003c\/strong\u003e: Y\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 (3\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 1.0000 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\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: P4816KE\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51727321432370,"sku":"P4816KE","price":18.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79c55b9503f5b2b51a95049f224e918b_c3086dad-02d8-4533-a0ef-0d708f056b52.jpg?v=1788676284","url":"https:\/\/voomisupply.com\/products\/boneham-p4816ke-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
