Manufactured from steel hardened to 60 to 65 HRC, this bushing delivers consistent hole location accuracy in jigs and fixtures. It features a 3\/8 inch inside diameter, a 3\/4 inch outside diameter, and an overall length of 1\/2 inch. The headless design allows flush or sub-flush seating in the jig plate without a protruding flange. Machinists, toolmakers, and fixture builders install this type of bushing in production and job-shop environments where tight positional tolerances are required.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jig plates across a range of metalworking and fabrication applications. Its press fit installation method makes it appropriate for permanent or semi-permanent fixture setups where the bushing is not intended to be routinely replaced. The inside diameter tolerance of +0.0001 to +0.0005 inches provides the close fit required to maintain drill or reamer guidance without excessive tool wobble. Typical users include machine shops, tooling departments, and precision fabrication facilities working to ANSI standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation for permanent fixture mounting without fasteners\u003c\/li\u003e\n  \u003cli\u003eHeadless design seats flush in jig plate for unobstructed tool travel\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for wear resistance\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0005 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for drill bushing geometry and fit\u003c\/li\u003e\n  \u003cli\u003eNon-renewable bushing intended for long-service permanent installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit bushing for drill jigs and fixtures requiring a press fit headless style bushing with a 3\/8 inch inside diameter and 3\/4 inch outside diameter per ANSI P-series specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePress fit bushings are installed by toolmakers or machinist personnel using an arbor press or hydraulic press to achieve the required interference fit in the jig plate bore. The jig plate bore must be machined to the correct tolerance to accept the bushing without damage to the bushing or the plate. Never drive the bushing in with impact tools, as this can distort the inside diameter and compromise tool guidance. Verify inside diameter after installation to confirm tolerance has been maintained.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\u003eInside Diameter\u003c\/strong\u003e: 0.3750 inches\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: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Headless\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 60 to 65 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbored\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRenewable\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\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: P488JQ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51740957638962,"sku":"P488JQ","price":16.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_2ea2e35d-95d8-4aca-8b77-b9ce989e3428.jpg?v=1788828588","url":"https:\/\/voomisupply.com\/products\/boneham-p488jq-press-fit-headless-drill-bushing-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
