Classified under Industry Code P, this bushing features a 0.159 inch (No. 21 wire gauge) inside diameter and a 5\/16 inch body outside diameter, with an overall length of 1\/2 inch. Machined from steel, it is pressed directly into a jig plate without a head or locking flange, keeping the top face of the fixture flush. The inside diameter tolerance is held to +0.0001 to +0.0004 inches, ensuring consistent tool guidance and repeatable hole location across production runs.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for use in drill jigs and fixture plates in metal fabrication, toolroom, and production machining environments. It is a non-renewable (fixed) style, meaning it is installed permanently in the jig rather than being designed for field replacement. Typical applications include guiding twist drills, reamers, or step drills in repetitive drilling operations where close positional accuracy is required. Installation is performed by toolmakers, machinists, or maintenance trades working with jig and fixture assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation — no head or flange for a flush, low-profile jig surface\u003c\/li\u003e\n\u003cli\u003eInside diameter: 0.159 inches (No. 21 wire gauge) with +0.0001 to +0.0004 inch tolerance\u003c\/li\u003e\n\u003cli\u003eBody outside diameter: 5\/16 inches; overall length: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003eSteel construction for wear resistance in repetitive drilling operations\u003c\/li\u003e\n\u003cli\u003eNon-renewable fixed style — permanently pressed into the jig plate\u003c\/li\u003e\n\u003cli\u003eIndustry Code P classification for standardized fitment in compatible jig plates\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Industry Code P press fit headless drill bushing for use in jig plates and fixture assemblies sized to accept a 5\/16 inch outside diameter pressed bushing.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePress fit bushings are installed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing flush and square in the jig plate bore. The receiving bore should be machined to the appropriate interference fit tolerance for the P-series bushing outside diameter before installation. Do not hammer bushings directly without a proper driver, as this can damage the bore or distort the bushing. Once pressed in, these bushings are not intended for removal and reuse.\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\u003c\/strong\u003e: 0.159 inches (No. 21 wire gauge)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 5\/16 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\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\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: P208EX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51733266334002,"sku":"P208EX","price":18.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9c2466ac506c49c68532d878633de0e0.jpg?v=1788753411","url":"https:\/\/voomisupply.com\/products\/boneham-p208ex-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
