It features a 23\/64-inch inside diameter, a 0.75-inch body outside diameter, and a 1-inch length under the head. The head measures 1-3\/64 inches in outside diameter with a 1\/4-inch head height. This type of bushing is used in jig and fixture applications to guide drill bits, reamers, and other cutting tools with precision. It installs by slipping into a liner bushing and locking in place, making it renewable and interchangeable without disturbing the fixture setup. Installation is performed by tool and die makers, machinists, and fixture builders.\u003c\/p\u003e\n\u003cp\u003eThe SF4816JJ is suited for use in drill jigs where repeatable hole location accuracy is required. The slip-fixed design allows the bushing to be rotated into a locked position, preventing it from turning or lifting during the drilling operation. It is compatible with an LS-1 lock screw for positive retention. This bushing meets ANSI standards and fits into standard SF-series liner bushings used in production and prototype fixture applications across metalworking and manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e23\/64-inch inside diameter with a tight tolerance of +0.0001 to +0.0005 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for long service life under repeated drilling cycles\u003c\/li\u003e\n  \u003cli\u003eSlip-fixed installation method locks into liner bushing with an LS-1 compatible lock screw\u003c\/li\u003e\n  \u003cli\u003eRenewable design allows bushing replacement without reworking the fixture or liner\u003c\/li\u003e\n  \u003cli\u003eHead style with 1-3\/64-inch outside diameter and 1\/4-inch head height for positive seating\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for drill bushing dimensions and fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard SF-series liner bushings and compatible with an LS-1 lock screw for secure retention in drill jig fixtures.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or tool and die makers during fixture setup or bushing replacement. Before servicing, ensure the fixture is secured and all associated machinery is powered down and locked out per applicable safety procedures. The bushing slips into a mating liner bushing and is rotated to engage the locking notch, then secured with the appropriate LS-1 lock screw. Do not force the bushing into an undersized liner, as this may damage the bore or compromise tool guidance accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 23\/64 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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 1-3\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1\/4 inch\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\u003eInstallation Method\u003c\/strong\u003e: Slip-Fixed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: SF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Screw Compatibility\u003c\/strong\u003e: LS-1\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\u003eRenewable\u003c\/strong\u003e: Yes\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: SF4816JJ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51728201089330,"sku":"SF4816JJ","price":21.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d089b0a7b36c5d4ca8f716b32e5b0d8a_622259ec-fce5-4b97-9b32-eb729ef35b76.jpg?v=1788689425","url":"https:\/\/voomisupply.com\/products\/boneham-sf4816jj-slip-fixed-drill-bushing-23-64-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
