Built to the SF industry code and conforming to ANSI standards, this bushing features a 21\/32-inch inside diameter and a 1-inch body outside diameter, with a 1-3\/8-inch length under the head. Hardened to 60 to 65 HRC, the steel construction resists wear under repeated tool passes. A flanged head with a 1-27\/64-inch outside diameter and 3\/8-inch height retains the bushing in the jig plate, while LS-2 lock screw compatibility secures it against rotation during use.\u003c\/p\u003e\n\u003cp\u003eThis bushing is intended for use in tooling plates, drill jigs, and production fixtures where a renewable, removable guide is required. The slip-fixed design allows the bushing to be locked in place during operation and removed for replacement without disturbing the liner bushing or the jig plate. It is suited for machine shops, metalworking facilities, and any production environment where consistent hole location accuracy across multiple workpieces is required. Licensed tool and die makers and machinist technicians are the typical installers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSF industry code bushing, conforming to ANSI standards\u003c\/li\u003e\n  \u003cli\u003eHardened steel construction, 60 to 65 HRC for extended tool wear resistance\u003c\/li\u003e\n  \u003cli\u003e21\/32-inch ID with a close tolerance of +0.0001 to +0.0005 inches for accurate tool guidance\u003c\/li\u003e\n  \u003cli\u003eRenewable design allows in-field replacement without jig plate rework\u003c\/li\u003e\n  \u003cli\u003eLS-2 lock screw compatible to prevent rotation under cutting loads\u003c\/li\u003e\n  \u003cli\u003eHeaded configuration for positive axial retention in the liner\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ANSI-standard SF-series slip-fixed drill bushing for use with LS-2 compatible lock screws in standard liner bushings sized to accept a 1-inch body outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified toolmakers or machinists. Before servicing a jig fixture, ensure all associated machinery is powered down and locked out in accordance with applicable lockout\/tagout procedures. The bushing is inserted into a seated liner bushing and secured with an LS-2 lock screw; do not force the bushing into an undersized or damaged liner. Verify inside diameter tolerance and head seating before putting the fixture back into production.\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\u003c\/strong\u003e: 21\/32 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: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 1-27\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Configuration\u003c\/strong\u003e: Headed\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\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-2\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: SF6422MM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51730802114866,"sku":"SF6422MM","price":27.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d089b0a7b36c5d4ca8f716b32e5b0d8a_3f1ad030-ca7d-4da7-b294-0aaa1057bb4f.jpg?v=1788723100","url":"https:\/\/voomisupply.com\/products\/boneham-sf6422mm-slip-fixed-drill-bushing-21-32-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
