Built to ANSI standards, this bushing features a 0.191 inch (No. 11 wire gauge) inside diameter with a tight tolerance of +0.0001 to +0.0004 inches, ensuring repeatable hole placement across production runs. The body outside diameter measures 0.5 inches with a head outside diameter of 51\/64 inches and a head height of 1\/4 inch. Manufactured from hardened steel at 60 to 65 HRC, it delivers long service life under high-cycle tooling conditions. Installed by machinists and toolmakers, this bushing is compatible with the LS-1 lock screw for secure retention in jig plates.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jigs and fixture plates in both job-shop and production machining environments. The slip-fixed design allows the bushing to be installed and locked in place using the LS-1 compatible lock screw, making it appropriate for operations where the same bushing remains in the fixture for extended runs. The length under head is 0.5 inches, providing adequate engagement depth for standard jig plate thicknesses. This part is classified under industry code SF and is renewable, allowing replacement without retooling the entire fixture.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInside diameter of 0.191 inches (No. 11 wire) with +0.0001 to +0.0004 inch tolerance for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eHardened steel construction at 60 to 65 HRC for wear resistance in high-cycle applications\u003c\/li\u003e\n  \u003cli\u003eHead-type bushing with 51\/64 inch head OD and 1\/4 inch head height for positive seating on jig plates\u003c\/li\u003e\n  \u003cli\u003eLS-1 lock screw compatible for secure, slip-fixed retention\u003c\/li\u003e\n  \u003cli\u003eRenewable bushing design allows field replacement without fixture rework\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for drill bushing dimensions and performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ANSI-standard slip-fixed drill bushing compatible with LS-1 lock screws and suitable for use in standard jig plates and fixture systems that accept SF-series head-type bushings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a machinist or toolmaker during jig assembly or bushing replacement. Press the bushing into the liner or jig plate bore and secure with an LS-1 lock screw to prevent rotation. Ensure the fixture and workpiece are clamped and all machine power is off before removing or installing bushings. Follow ANSI and shop-floor safety procedures when handling hardened components.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Wire Gauge)\u003c\/strong\u003e: No. 11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.191 inches\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: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 51\/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\u003eLength Under Head\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Material\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\u003eHead Type\u003c\/strong\u003e: Head\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  \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: SF328FV\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51727865348402,"sku":"SF328FV","price":20.08,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/boneham-sf328fv-slip-fixed-drill-bushing-0-191-in-id-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
