Built to ANSI standards, this steel bushing features a 0.377 inch inside diameter (Letter V) and a 0.75 inch body outside diameter, making it a direct fit for standard SF-series jig tooling setups. The hardened steel construction is rated 60 to 65 HRC, providing wear resistance suited to high-cycle production and toolroom environments. It includes a head and is compatible with the LS-1 lock screw for secure retention in the liner bushing. Machinists, tool and die makers, and fixture builders are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis bushing is used in drill jigs and fixture plates where repeatable hole location is critical. The slip-fixed design allows the bushing to be installed and locked in place through a head-style body that seats against the jig plate surface. With a 1.375 inch length under the head and a head outside diameter of approximately 1.047 inches (1-3\/64 inches), it suits moderate plate thicknesses common in production machining fixtures. It is renewable, meaning it can be replaced without retooling the fixture liner, reducing downtime in high-volume drilling operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eANSI-standard SF-series slip-fixed bushing for use with standard liner bushings\u003c\/li\u003e\n  \u003cli\u003e0.377 inch (Letter V) inside diameter with a tight tolerance of +0.0001 to +0.0005 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eHardened steel construction rated 60 to 65 HRC for extended service life\u003c\/li\u003e\n  \u003cli\u003eHead-style body with 1.375 inch length under head for secure seating in jig plates\u003c\/li\u003e\n  \u003cli\u003eCompatible with LS-1 lock screw for positive retention during operation\u003c\/li\u003e\n  \u003cli\u003eRenewable design allows in-place replacement without modifying the fixture\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ANSI-standard SF-series liner bushings and LS-1 lock screws in drill jig and fixture applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a machinist or tool and die maker during fixture assembly or bushing replacement. Power down and lock out any associated machine before servicing a drill jig. Press or hand-seat the bushing into the compatible liner bushing, then secure with the LS-1 lock screw to prevent rotation during drilling. Inspect the inside diameter for burrs or contamination before installation to maintain tool guidance accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 1.047 inches (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 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\u003eHardness\u003c\/strong\u003e: 60 to 65 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbored\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRenewable\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\u003eBushing Industry Code\u003c\/strong\u003e: SF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\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: SF4822JR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51730122211634,"sku":"SF4822JR","price":27.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d089b0a7b36c5d4ca8f716b32e5b0d8a_df2d206c-ac71-4a5d-b114-15172476f954.jpg?v=1788712079","url":"https:\/\/voomisupply.com\/products\/boneham-sf4822jr-slip-fixed-drill-bushing-0-377-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
