Built to industry code SF, this bushing features a 0.052 inch inside diameter sized for a No. 55 wire gauge drill, a 5\/16 inch body outside diameter, and a 1\/2 inch length under head. The head outside diameter measures 35\/64 inch with a 1\/4 inch head height. Constructed from steel, it is designed for renewable installation and is counterbored to accept an LS-1 compatible lock screw. Inside diameter tolerance is held to a tight plus 0.0001 to plus 0.0004 inch range, ensuring consistent hole location across repeated drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis bushing is used in drill jigs and production fixtures where repeatable hole placement is required. The slip-fixed configuration allows the bushing to be installed and locked in place via a lock screw, making it suitable for applications that require occasional bushing removal or replacement during a machining run. Typical users include tool and die makers, machinists, and fixture builders working in metalworking, fabrication, or precision manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSF industry code slip-fixed design with counterbore for LS-1 lock screw\u003c\/li\u003e\n  \u003cli\u003e0.052 inch inside diameter (No. 55 wire gauge) with tolerance of plus 0.0001 to plus 0.0004 inch\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch body outside diameter and 1\/2 inch length under head\u003c\/li\u003e\n  \u003cli\u003e35\/64 inch head outside diameter and 1\/4 inch head height\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in repetitive drilling operations\u003c\/li\u003e\n  \u003cli\u003eRenewable bushing design allows replacement without disturbing the jig plate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct fit for drill jig fixtures requiring an SF-series slip-fixed bushing with LS-1 lock screw compatibility.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or tool and die technicians. The bushing is pressed or slipped into a counterbored liner bushing already installed in the jig plate, then secured with an LS-1 lock screw. Ensure the mating liner bushing bore and the jig plate are clean and free of chips or burrs before seating. Always verify drill press or machining center is fully stopped and de-energized before changing or inspecting bushings.\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 (Wire)\u003c\/strong\u003e: No. 55\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 Tolerance\u003c\/strong\u003e: plus 0.0001 to plus 0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 35\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbored\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRenewable Bushing\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Screw Compatibility\u003c\/strong\u003e: LS-1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171603\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: SF208BJ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51728100000050,"sku":"SF208BJ","price":56.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d03feb7d4aa25b0ceb04fc5a720ede9f.jpg?v=1788687949","url":"https:\/\/voomisupply.com\/products\/boneham-sf208bj-slip-fixed-drill-bushing-0-052in-id-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
