Built to ANSI standards, it features a 0.136 inch inside diameter (wire size No. 29), a 0.25 inch body outside diameter, and a 0.25 inch length under head. The hardened steel construction is rated 60 to 65 HRC, providing the wear resistance required for high-cycle jig and fixture work. A 7\/16 inch head outside diameter and 0.25 inch head height allow positive seating in standard drill jig plates. This bushing is renewable and compatible with LS-TW-2 lock screws, making it suitable for tooling setups that require periodic bushing replacement without disturbing the jig body.\u003c\/p\u003e\u003cp\u003eThe SFT164EC is used in drill jigs and production fixtures across machining, fabrication, and toolmaking environments. The slip-fixed configuration allows the bushing to be removed and replaced by hand or with a bushing driver once the lock screw is released. It is appropriate for small-diameter hole operations in both prototype and production settings where repeatable hole location is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHardened steel body rated 60 to 65 HRC for extended wear life in high-cycle applications\u003c\/li\u003e\n\u003cli\u003eANSI-standard SF series slip-fixed design for removable, renewable tool guidance\u003c\/li\u003e\n\u003cli\u003eInside diameter tolerance of +0.0001 to +0.0004 inches for precise tool guidance\u003c\/li\u003e\n\u003cli\u003eCompatible with LS-TW-2 lock screws for secure retention in the jig plate\u003c\/li\u003e\n\u003cli\u003eHead-style configuration with 7\/16 inch head OD seats flush against jig plate surface\u003c\/li\u003e\n\u003cli\u003eNot counterbored, simplifying installation in standard drill jig plates\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a renewable ANSI SF series slip-fixed bushing compatible with LS-TW-2 lock screws.

Before replacing a bushing in an active fixture, ensure all cutting tools are removed and the jig is secured. The bushing slip-fits into the jig plate liner and is locked in place with a compatible LS-TW-2 lock screw. Use a proper bushing press or driver to seat the bushing squarely without applying force to the head flange.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Series\u003c\/strong\u003e: SF (Slip-Fixed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Wire)\u003c\/strong\u003e: No. 29\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.136 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 0.4375 inches (7\/16 inch)\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 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\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\u003eLock Screw Compatibility\u003c\/strong\u003e: LS-TW-2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: SFT164EC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51736599626034,"sku":"SFT164EC","price":24.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d089b0a7b36c5d4ca8f716b32e5b0d8a_5410f322-d4dd-4b4b-b3ca-cc2d8148faf2.jpg?v=1788778890","url":"https:\/\/voomisupply.com\/products\/boneham-sft164ec-slip-fixed-drill-bushing-0-136-in-id-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
