It features a 3\/8 inch inside diameter, a 5\/8 inch body outside diameter, and a 3\/4 inch length under the head. Machined from steel and hardened to 60 to 65 HRC, this bushing provides the wear resistance required for repetitive production work. The headed design seats securely in a jig plate, and the renewable configuration allows field replacement without scrapping the entire fixture. Compatible with the LS-TW-2 lock screw for positive retention. Installed by toolmakers, machinists, and fixture builders working to ANSI standards.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jigs and fixture plates in production machining environments. It is appropriate for applications where a guided, slip-in renewable bushing is required and where a lock screw must hold the bushing against rotation and axial movement during the cut. The headed style seats flush against the jig plate surface, providing a positive stop at a fixed depth. Typical applications include high-volume hole-location work in metal fabrication, aerospace, and general manufacturing shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSlip-fixed installation method with headed design for positive axial seating\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for extended wear life\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch ID with a tolerance of +0.0001 to +0.0005 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eRenewable bushing design allows replacement in the liner without fixture rework\u003c\/li\u003e\n  \u003cli\u003eLS-TW-2 lock screw compatible for secure rotational and axial retention\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for drill bushing geometry and tolerancing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with the LS-TW-2 lock screw.

Ensure the mating liner bushing bore and the jig plate are clean and free of burrs before seating the bushing. Engage the LS-TW-2 lock screw to secure the bushing before beginning any drilling operation. Never run a cutting tool through the bushing without confirming the lock screw is fully seated and the bushing is flush against the jig plate.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 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: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 7\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/4 inch\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 Style\u003c\/strong\u003e: Head\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-TW-2\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\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.37 pounds\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: SFT4012JQ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51731938246962,"sku":"SFT4012JQ","price":22.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d089b0a7b36c5d4ca8f716b32e5b0d8a_d19ce602-d759-4fc4-877f-c5a5276f34ac.jpg?v=1788736909","url":"https:\/\/voomisupply.com\/products\/boneham-sft4012jq-slip-fixed-drill-bushing-3-8-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
