This is an Industry Code P bushing with an inside diameter of 0.377 inches, a body outside diameter of 5\/8 inches, and an overall length of 3\/4 inches. Manufactured from steel with a hardness rating of 60 to 65 HRC, this bushing provides the wear resistance required for sustained use in jig plates and fixture tooling. It is a permanent, non-renewable bushing installed without a head for flush or sub-flush mounting applications.\u003c\/p\u003e\u003cp\u003eThis bushing is used in industrial manufacturing, machine shop, and toolroom environments where repeatable hole location accuracy is critical. It seats directly into a drill jig or fixture plate using a press fit installation method, eliminating the need for a locking collar or retaining hardware. Typical users include machinist tool builders, fixture engineers, and production floor personnel working on metal fabrication setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation — no locking collar or set screw required\u003c\/li\u003e\n\u003cli\u003eHeadless design allows flush or sub-flush seating in jig plates\u003c\/li\u003e\n\u003cli\u003eInside diameter of 0.377 inches to 0.3775 inches within tolerance (+0.0001 to +0.0005 inches)\u003c\/li\u003e\n\u003cli\u003eSteel construction hardened to 60 to 65 HRC for wear resistance\u003c\/li\u003e\n\u003cli\u003eNon-renewable fixed bushing for permanent fixture applications\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards for drill bushing dimensions and tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit bushing for drill jigs and fixture plates requiring an Industry Code P press fit headless bushing with a 0.377 inch ID and 5\/8 inch OD.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or toolroom professional using a hydraulic or arbor press to seat the bushing into a properly reamed hole in the jig plate. Power down and lock out any associated machine tool before servicing a fixture. Do not hammer the bushing directly without a proper driver to avoid distorting the bore or damaging the seating surface. Verify hole diameter in the jig plate matches the bushing OD tolerance before pressing to ensure proper interference fit.\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: 0.377 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter)\u003c\/strong\u003e: V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 0.75 inches (3\/4 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\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\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: P4012JR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51744655540530,"sku":"P4012JR","price":16.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_7c40e0d4-796a-4dfa-9a17-971c438b730f.jpg?v=1788859605","url":"https:\/\/voomisupply.com\/products\/boneham-p4012jr-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
