Classified under industry code SF, this bushing features a 0.199 inch (No. 8 wire) inside diameter with a tight tolerance of +0.0001 to +0.0004 inches, a 0.375 inch body outside diameter, and a 0.625 inch head outside diameter. Constructed from steel for durability in repeated production use, it installs into a prepared drill jig plate without a liner bushing. It is renewable and secured with an LS-TW-2 compatible lock screw, keeping the bushing positively located under cutting forces.\u003c\/p\u003e\n\u003cp\u003eThis bushing suits tooling rooms, machine shops, and production environments where precise hole location must be maintained across repeated part runs. It is appropriate for jig-and-fixture setups in light to medium manufacturing, typically installed by machinists, toolmakers, and fixture builders. The head style provides a positive stop against the jig plate surface, helping maintain consistent tool depth and preventing the bushing from being pushed through the plate during operation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSlip-fixed (SF) installation method — renewable design allows bushing replacement without replacing the liner\u003c\/li\u003e\n  \u003cli\u003eInside diameter: 0.199 inches (No. 8 wire size) with precision tolerance of +0.0001 to +0.0004 inches\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance in high-cycle drilling and reaming applications\u003c\/li\u003e\n  \u003cli\u003eHead outside diameter of 0.625 inches with a 0.25 inch head height for positive seating on jig plate\u003c\/li\u003e\n  \u003cli\u003eLS-TW-2 compatible lock screw secures bushing in position during production use\u003c\/li\u003e\n  \u003cli\u003eNot counterbored — standard through-hole bushing configuration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with LS-TW-2 lock screws for secure installation in slip-fixed drill jig applications.

The mating jig plate bore must be machined to the appropriate slip-fixed liner or plate tolerance before pressing or inserting this bushing. Always confirm the lock screw is fully engaged before operating the drill press or machining center. Inspect bushing inside diameter for wear periodically and replace as needed, as the renewable design allows swap-out without reworking the fixture plate.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.199 inches (No. 8 wire size)\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: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 0.625 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\u003eLength Under Head\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: SF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\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\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\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: SFT246GB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51732015022386,"sku":"SFT246GB","price":21.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f13c045e5a2ce60043c7847b5d0cbbe0_95ebe9fb-28af-4d37-9c5a-9c3708775ed4.jpg?v=1788738129","url":"https:\/\/voomisupply.com\/products\/boneham-sft246gb-slip-fixed-drill-bushing-0-199-in-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
