It features a 0.25-inch inside diameter, a 7\/16-inch (0.4375-inch) body outside diameter, and a 5\/8-inch (0.625-inch) overall length. Manufactured from steel and hardened to 60-65 HRC, this bushing delivers the wear resistance required for repeated drilling operations in production environments. The headless design allows it to sit flush within the jig plate, keeping the work surface clear. Inside diameter tolerance is held to +0.0001 to +0.0004 inches for consistent, repeatable hole location. Licensed machinists, toolmakers, and fixture builders typically specify and install this component.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jigs, fixture plates, and tooling assemblies where a permanent, non-renewable press fit installation is required. The P industry code designation follows ANSI standards for drill bushing sizing and interchangeability, making it straightforward to specify on engineering drawings. It is commonly used in metalworking, fabrication, and precision machining shops handling repetitive hole-drilling operations that demand tight positional accuracy across multiple workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation — no set screw or locking collar required\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush with jig plate surface\u003c\/li\u003e\n  \u003cli\u003e0.25-inch inside diameter with +0.0001 to +0.0004 inch tolerance\u003c\/li\u003e\n  \u003cli\u003eHardened steel construction at 60-65 HRC for extended wear life\u003c\/li\u003e\n  \u003cli\u003eANSI standard P-series industry code for drawing specification compatibility\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 ANSI-standard P-series press fit headless drill bushing suitable for use in drill jigs and fixture plates requiring a 7\/16-inch diameter installation bore and a 0.25-inch nominal drill guide.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePress fit bushings are installed by toolmakers or machinists using an arbor press or hydraulic press — never hammer directly on the bushing face, as this can damage the bore or distort the outer diameter. The receiving hole in the jig plate must be machined to the correct interference fit tolerance before installation. Once pressed in, this bushing is not intended for removal or replacement. Always verify bore alignment before pressing to final depth.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inches)\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: 0.4375 inches (7\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.625 inches (5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 60-65 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Headless\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRenewable\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\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: PT2810HG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51736754815282,"sku":"PT2810HG","price":16.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_ad65c9ce-0e4e-4cc1-9ea9-f51bef1acc89.jpg?v=1788779953","url":"https:\/\/voomisupply.com\/products\/boneham-pt2810hg-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
