Built from steel, this bushing features an inside diameter of 0.316 inches with a tight tolerance of +0.0001 to +0.0005 inches, a body outside diameter of 0.5625 inches, and a length under head of 0.75 inches. The head measures 0.875 inches in outside diameter and 0.25 inches in height. The slip-fixed installation method allows the bushing to be locked in place using a compatible lock screw, making it a renewable component that can be removed and replaced without disturbing the drill jig plate.\u003c\/p\u003e\u003cp\u003eThis bushing is used in industrial drill jig setups across metal fabrication, machine shops, and production environments where repeatable hole location accuracy is required. The slip-fixed design suits applications where bushings need to be changed out for different tool sizes or replaced after wear without retooling the fixture plate. Machinists, tool and die makers, and fixture builders install this type of component as part of hardened jig assemblies. The inside diameter letter designation is O, corresponding to the 0.316-inch decimal dimension per standard bushing sizing conventions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSlip-fixed installation method allows field removal and replacement without fixture plate modification\u003c\/li\u003e\n\u003cli\u003eInside diameter of 0.316 inches with precision tolerance of +0.0001 to +0.0005 inches for consistent tool guidance\u003c\/li\u003e\n\u003cli\u003eSteel construction provides durability in repetitive drilling operations\u003c\/li\u003e\n\u003cli\u003eHeaded design with 0.875-inch head OD and 0.25-inch head height for positive seating against the jig plate surface\u003c\/li\u003e\n\u003cli\u003eRenewable bushing rated for lock screw compatibility with LS-TW-2 style fasteners\u003c\/li\u003e\n\u003cli\u003eCounterbored: No — flush or surface-mounted fixture plate installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with LS-TW-2 lock screws for secure retention in slip-fixed bushing applications.

Ensure the jig plate bore and bushing body OD are clean and free of chips or burrs before installation. Secure the bushing using a compatible LS-TW-2 lock screw to prevent rotation or axial movement during drilling operations. Always verify tool clearance and bushing alignment before running cutting tools through the assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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\u003eInside Diameter (Letter)\u003c\/strong\u003e: O\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.316 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: 0.5625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 0.875 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 or Headless\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 Bushing\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLock Screw Compatibility\u003c\/strong\u003e: LS-TW-2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.37 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171603\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: SFT3612IO\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51728668426546,"sku":"SFT3612IO","price":22.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee4bd24b5c157eb314635e1eef8d2a78.jpg?v=1788694663","url":"https:\/\/voomisupply.com\/products\/boneham-sft3612io-slip-fixed-drill-bushing-0-316-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
