Built to industry code SF, this head-type bushing features a 0.242 inch inside diameter (Letter C), a 7\/16 inch body outside diameter, and a 5\/8 inch head outside diameter. The inside diameter is held to a tight tolerance of +0.0001 to +0.0004 inches, ensuring consistent tool guidance and repeatable hole location. Constructed from steel, the SFT284HB delivers the hardness and wear resistance required for production jig and fixture applications. It is a renewable bushing, meaning it can be replaced in the liner without disturbing the jig plate.\u003c\/p\u003e\n\u003cp\u003eThe SFT284HB is used in drill jig fixtures across metalworking, fabrication, and machining environments. Its slip-fixed installation method allows the bushing to be rotated into a locked position within a liner bushing, making it suitable for applications where the bushing must be secured during the cut but also needs periodic replacement due to wear. The 1\/4 inch length under head and headless-free head design make it appropriate for standard jig plate thicknesses encountered in production and toolroom settings. Machinists, tool and die makers, and fixture builders are the primary installers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSlip-fixed (SF) installation method locks bushing in place during drilling operations\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.242 inches (Letter C) with tolerance of +0.0001 to +0.0004 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides hardness and wear resistance for repeat-use jig applications\u003c\/li\u003e\n  \u003cli\u003eRenewable design allows replacement within an existing liner bushing without reworking the jig plate\u003c\/li\u003e\n  \u003cli\u003eCompatible with LS-TW-2 lock screw for secure retention\u003c\/li\u003e\n  \u003cli\u003eHead outside diameter of 5\/8 inch and head height of 1\/4 inch seat flush against standard jig plate surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with LS-TW-2 compatible lock screws and intended as a renewable slip-fixed bushing for standard drill jig liner applications in production and toolroom fixture setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or tool and die makers during jig assembly or bushing replacement. Power down and secure any associated machinery before servicing a jig fixture. The bushing is inserted into a mating liner bushing and rotated to the locked position using the head drive slot and a compatible lock screw. Do not force the bushing into a liner with an undersized or worn bore, as this can compromise the inside diameter tolerance and tool guidance accuracy.\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\u003eInstallation Method\u003c\/strong\u003e: Slip-Fixed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.242 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter)\u003c\/strong\u003e: C\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: 0.4375 inches (7\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\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\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-TW-2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\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: SFT284HB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51729071276338,"sku":"SFT284HB","price":20.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f13c045e5a2ce60043c7847b5d0cbbe0_9aad709d-1108-4426-b89c-1df358efe6c7.jpg?v=1788699549","url":"https:\/\/voomisupply.com\/products\/boneham-sft284hb-slip-fixed-drill-bushing-0-242-in-id-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
