Koswork Hex Wrench Tip 3.0x75mm 1/4in Drive Tool - KOS13207-H30

The Koswork KOS13207-H30 is a 3.0mm hex wrench tip with a 1/4" drive shank and 75mm overall length, designed for use with 1/4" drive handles and bit holders when working on RC cars and other hobby builds. The 3.0mm size is a common fastener size across RC car chassis, suspension components, and drivetrain hardware, making this a practical addition to any RC tool setup. Koswork produces the KOS13207-H30 as a standalone tip, so it can replace a worn bit or expand an existing 1/4" drive hex key system without buying a full set.
