Manufactured from steel, this bushing features an inside diameter of 0.116 inches (wire gauge #32) with a tight tolerance of +0.0001 to +0.0004 inches, ensuring consistent hole location and repeatable accuracy across production runs. The outside diameter measures 1\/4 inch with an overall length of 1\/2 inch. It installs without mechanical fasteners, relying on an interference press fit to seat flush in the jig plate. Machinists, tool and die makers, and fixture builders are the primary users of this component.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for use in drill jigs, fixture plates, and tooling setups where a permanent, headless installation is required. The headless profile allows the bushing to sit flush with or below the surface of the jig plate, making it appropriate for applications where a protruding flange would interfere with the workpiece or tooling clearance. Industry code P identifies the bushing type within standard tooling catalogs, simplifying cross-referencing for fixture builders sourcing replacements or building new fixtures to standard specifications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation — no fasteners required, seats permanently in jig plate bore\u003c\/li\u003e\n\u003cli\u003eHeadless design sits flush with plate surface for unobstructed tool approach\u003c\/li\u003e\n\u003cli\u003eInside diameter of 0.116 inches (wire gauge #32) with tolerance of +0.0001 to +0.0004 inches\u003c\/li\u003e\n\u003cli\u003eSteel construction for wear resistance in repetitive drilling operations\u003c\/li\u003e\n\u003cli\u003eIndustry code P for straightforward catalog cross-referencing\u003c\/li\u003e\n\u003cli\u003eOverall length of 1\/2 inch suits standard jig plate thicknesses\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, compatible with jig plates and fixtures bored to accept a 1\/4 inch OD press fit bushing per standard tooling specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by pressing the bushing into a precisely bored hole using an arbor press or hydraulic press — never hammer directly on the bushing face, as this can distort the bore. The receiving hole in the jig plate must be machined to the correct interference fit tolerance to ensure the bushing seats without rotation or pullout during service. Verify that all cutting operations on the jig plate are complete before pressing the bushing in, as the bushing is not designed for repeated removal and reinstallation.\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 (Decimal)\u003c\/strong\u003e: 0.116 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Wire Gauge)\u003c\/strong\u003e: #32\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 (1\/4 inch)\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\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\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171603\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: P168DQ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51735553638706,"sku":"P168DQ","price":21.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/65349baa7952a56c3efa6b4b166d5de7.jpg?v=1788772995","url":"https:\/\/voomisupply.com\/products\/boneham-p168dq-press-fit-headless-drill-bushing-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
