Built to Industry Code P, this bushing features a 0.397-inch inside diameter, a 5\/8-inch outside diameter, and a 5\/16-inch overall length. Constructed from steel, it is pressed directly into a jig or fixture plate without a retaining head, providing a low-profile seating surface where clearance is limited. The inside diameter tolerance of +0.0001 to +0.0005 inches ensures consistent hole location accuracy across repeated drilling cycles. Machinists, tool-and-die makers, and fixture builders install this type of bushing in production and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jigs where a permanent, non-renewable guide is required. Its headless design makes it appropriate for applications where a flush or recessed installation is necessary and a flanged head would interfere with workpiece seating or clamping. Typical use cases include production drilling fixtures in metalworking shops, maintenance jigs for repetitive hole patterns, and custom tooling plates across light to medium industrial applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation — no retaining ring or fastener required\u003c\/li\u003e\n  \u003cli\u003eHeadless design allows flush or below-surface mounting in jig plates\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0005 inches for consistent tool guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under repeated drilling loads\u003c\/li\u003e\n  \u003cli\u003eBushing Industry Code P for standard jig-plate compatibility\u003c\/li\u003e\n  \u003cli\u003eNon-renewable design — intended as a permanent fixture component\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style press fit headless drill bushing for use in standard jig and fixture plates requiring an Industry Code P bushing with a 0.397-inch inside diameter and 5\/8-inch outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolmakers using an arbor press or hydraulic press to seat the bushing flush into a correctly sized jig plate bore. The receiving bore in the fixture plate must be machined to the appropriate tolerance to achieve proper interference fit and prevent rotation or pullout during use. Always confirm bore diameter and depth before pressing to avoid bushing damage or misalignment. Do not drive the bushing with impact tools, as this can deform the ID or cause out-of-round conditions.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.397 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.3970 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter Size)\u003c\/strong\u003e: X\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: 0.625 inches (5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 0.3125 inches (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\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: P405KA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51737523847474,"sku":"P405KA","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79c55b9503f5b2b51a95049f224e918b_dae2f667-6bef-4541-9536-fb90a9bb283f.jpg?v=1788789741","url":"https:\/\/voomisupply.com\/products\/boneham-p405ka-press-fit-headless-drill-bushing-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
