Built to ANSI standards, this SF-series bushing features a 0.368 inch inside diameter with a tight tolerance of +0.0001 to +0.0005 inches, a 0.75 inch body outside diameter, and a 0.5 inch length under head. Constructed from steel and hardened to 60 to 65 HRC, it delivers consistent, repeatable drill guidance under demanding production conditions. The headed design and renewable configuration allow it to be replaced without disturbing the jig plate. It is compatible with the LS-1 lock screw for secure retention during operation.\u003c\/p\u003e\n\u003cp\u003eThis bushing is used in drill jig plates across metalworking, machining, and fabrication environments. The slip-fixed design allows the bushing to be installed and locked in place through a compatible liner bushing, making it well suited for operations that require periodic bushing changes between production runs. Machinists, tool-and-die makers, and fixturing technicians install this part in both manual and CNC-assisted jig setups where accurate drill guidance is critical to hole quality and part repeatability.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSF-series slip-fixed bushing per ANSI standards for consistent jig fitment\u003c\/li\u003e\n  \u003cli\u003e0.368 inch inside diameter with inside diameter tolerance of +0.0001 to +0.0005 inches for precise drill guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for extended wear life\u003c\/li\u003e\n  \u003cli\u003eHeaded design with 1-3\/64 inch head outside diameter and 1\/4 inch head height\u003c\/li\u003e\n  \u003cli\u003eRenewable bushing configuration supports quick changeout without jig plate rework\u003c\/li\u003e\n  \u003cli\u003eLS-1 lock screw compatible for positive retention during drilling operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ANSI SF-series renewable slip-fixed bushing for use with standard liner bushings and LS-1 compatible lock screws in drill jig and fixture assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a machinist or tooling technician using a bushing press or arbor press to seat the bushing into a compatible liner. Ensure the jig plate and liner bushing are clean and free of chips before pressing the SF488JN into position. Secure the bushing with an LS-1 lock screw after installation. Do not hammer the bushing directly without a proper driver to avoid damaging the head or bore.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: SF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter)\u003c\/strong\u003e: U\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.368 inches\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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 1-3\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead or Headless\u003c\/strong\u003e: Head\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: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbored\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Screw Compatibility\u003c\/strong\u003e: LS-1\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\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: SF488JN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51729311662386,"sku":"SF488JN","price":20.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d089b0a7b36c5d4ca8f716b32e5b0d8a_a13b48fa-2b06-4806-bc2c-9c1a0ef80cd4.jpg?v=1788702769","url":"https:\/\/voomisupply.com\/products\/boneham-sf488jn-slip-fixed-drill-bushing-0-368-in-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
