Manufactured from steel with a hardness rating of 60 to 65 HRC, this bushing delivers the wear resistance needed for repetitive drilling applications. It features a 0.136 inch inside diameter, a 0.25 inch body outside diameter, and a 0.5 inch overall length. The headless design allows it to sit flush within a jig plate, making it well suited for close-tolerance work where a flanged head would interfere with the workpiece or fixture setup.\u003c\/p\u003e\n\u003cp\u003eThis bushing is used in drill jig applications across metalworking, tool and die, and general manufacturing environments. The press fit installation method locks the bushing permanently into the jig plate without the need for a locking mechanism or collar. It conforms to ANSI standards and carries the industry code P, which identifies the bushing type within the standard press fit headless series. Machinists, tool makers, and fixture builders working in job shops or production facilities are the primary installers of this component.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation method — no locking ring or collar required\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush with jig plate surface for unobstructed tool entry\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for extended service life\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0004 inches for precise drill guidance\u003c\/li\u003e\n  \u003cli\u003eInside diameter sized for a Number 29 wire gauge drill bit\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI standards, bushing industry code P\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard fit component for drill jig plates and fixtures requiring a press fit headless bushing with a 0.136 inch inside diameter and a 0.25 inch outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePress fit bushings are installed by machinists or tool makers using an arbor press or hydraulic press — never drive with a hammer, as impact can damage the bushing bore or the jig plate seat. Ensure the receiving hole in the jig plate is machined to the correct toleranced diameter before pressing to avoid distortion of the inside diameter. Power down all associated machinery before servicing or replacing bushings in an active fixture.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.136 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Wire Gauge)\u003c\/strong\u003e: Number 29\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: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 0.5 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\u003eBushing Industry Code\u003c\/strong\u003e: P\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\u003eRenewable Bushing\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\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\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: P168EC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51745942733106,"sku":"P168EC","price":22.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_97d53ccd-8ac9-46c6-91d0-bd21f89633eb.jpg?v=1788865816","url":"https:\/\/voomisupply.com\/products\/boneham-p168ec-press-fit-headless-drill-bushing-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
