Built to industry code SF, this bushing features a 25\/32 inch inside diameter and a 1 inch body outside diameter, with a 1-3\/4 inch length under the head. Constructed from steel hardened to 60 to 65 HRC, it delivers the wear resistance required for repeated tooling operations. The headed design and LS-2 compatible lock screw interface allow secure, tool-free removal when the jig plate setup demands bushing changes between operations. It meets ANSI standards and carries a renewable bushing designation, meaning it is engineered for use with a liner bushing already pressed into the jig plate.\u003c\/p\u003e\n\u003cp\u003eThis bushing is used in production drilling, reaming, and boring fixtures across metalworking, toolroom, and precision machining environments. It installs into a compatible liner bushing seated in the jig plate, locking in place via an LS-2 series lock screw. The SF slip-fixed configuration is a common choice where multiple bushing sizes must be swapped at the same station without disturbing the liner. Typical installers include toolmakers, fixture builders, and machining setup technicians working in both job shop and production floor settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSF industry-code slip-fixed design for use with pressed-in liner bushings\u003c\/li\u003e\n  \u003cli\u003e25\/32 inch inside diameter with a tight tolerance of +0.0002 to +0.0006 inches for accurate tool guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for high wear resistance\u003c\/li\u003e\n  \u003cli\u003eHeaded design with 1-27\/64 inch head outside diameter and 3\/8 inch head height\u003c\/li\u003e\n  \u003cli\u003eLS-2 compatible lock screw interface for positive retention in the liner bushing\u003c\/li\u003e\n  \u003cli\u003eRenewable bushing designation — interchangeable at the same liner station\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for drill bushing dimensions and tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with LS-2 series lock screws and compatible SF-style liner bushings.

The liner bushing must already be pressed and seated in the jig plate before installing this slip-fixed bushing. Secure the bushing using an LS-2 compatible lock screw tightened to the fixture plate face. Always confirm the inside diameter and length under head match the tooling and plate thickness requirements before committing to production runs.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 25\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0002 to +0.0006 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 1 inch (1.0000 inches decimal)\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\u003eLength Under Head\u003c\/strong\u003e: 1-3\/4 inches\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\u003eHead Style\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\u003eLock Screw Compatibility\u003c\/strong\u003e: LS-2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRenewable Bushing\u003c\/strong\u003e: Yes\u003c\/li\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\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: SF6428NH\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51737431802162,"sku":"SF6428NH","price":31.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d089b0a7b36c5d4ca8f716b32e5b0d8a_b210a9ce-a8a7-47b8-bc83-7716764898a9.jpg?v=1788788482","url":"https:\/\/voomisupply.com\/products\/boneham-sf6428nh-slip-fixed-drill-bushing-25-32-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
