Carrying industry bushing code P, it features an inside diameter of 0.052 inches (wire size 55) with a tight tolerance of +0.0001 to +0.0004 inches, an outside diameter of 3\/16 inches, and an overall length of 1\/2 inch. The headless profile allows flush seating in bushing plates where a protruding flange would interfere with workpiece clamping or tooling clearance. Machinists, tool and die makers, and precision fabricators install this bushing in drill jigs to maintain consistent hole location across repeated operations.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for production drilling, reaming, and related hole-making operations in both shop and manufacturing environments. Its press fit installation method makes it a permanent fixture component, appropriate for applications where the bushing will not require routine replacement. The steel construction holds up to the wear generated by repeated tool passes. It is typically found in drill jig plates used in metalworking, maintenance, and light industrial fabrication settings where tight positional tolerances are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIndustry bushing code P press fit headless design for flush, permanent installation\u003c\/li\u003e\n\u003cli\u003eInside diameter of 0.052 inches (wire size 55) with tolerance of +0.0001 to +0.0004 inches for precise drill guidance\u003c\/li\u003e\n\u003cli\u003eBody outside diameter of 3\/16 inches and overall length of 1\/2 inch\u003c\/li\u003e\n\u003cli\u003eSteel construction for wear resistance in repetitive drilling operations\u003c\/li\u003e\n\u003cli\u003eNon-renewable design intended for permanent jig plate mounting\u003c\/li\u003e\n\u003cli\u003eNon-counterbored body for straightforward press fit seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for drill jig plates and fixtures requiring a headless press fit bushing with a 3\/16-inch outside diameter and 0.052-inch inside diameter bore.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePress fit bushings are installed by qualified machinists or toolmakers using an arbor press or hydraulic press to drive the bushing flush into a precision-bored jig plate hole. The receiving hole in the jig plate must be machined to the correct interference fit specification to achieve proper retention. Always ensure the bushing is properly aligned before applying press force to avoid galling or misalignment. Remove any chips or debris from the bore before installation.\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\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.052 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Wire Size)\u003c\/strong\u003e: 55\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: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 0.5 inches (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\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: PT128BJ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51748098736434,"sku":"PT128BJ","price":50.9,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/554a9869bbe3e53e098d6435047d3c19.jpg?v=1788889045","url":"https:\/\/voomisupply.com\/products\/boneham-pt128bj-press-fit-headless-drill-bushing-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
