5-19 mm Hex Bit with 10 mm Hex Drive Shank

When one hex size wears out or disappears from your kit, there is no reason to replace the entire set. This 19 mm bit delivers exactly the size you need so you can get back to work without overspending on sizes you already own.

Measuring 75 mm (approximately 3 inches) in overall length, the bit provides the reach that shorter alternatives lack. Recessed fasteners buried inside machine frames, engine bays, and structural assemblies become accessible without awkward angling or extension stacking. The longer profile also improves leverage geometry for more efficient torque application.

A 10 mm hex drive shank is built for the higher torque loads that larger fastener sizes demand. It seats firmly into any standard 12 mm bit holder, adapter, or drive wrench, providing confident engagement with minimal play. Whether you drive it by hand or connect through a power-tool adapter, the shank interface is ready for the task.

The 19 mm tip is manufactured to match metric hex fastener dimensions precisely. Full contact across the tip surfaces protects against rounding and cam-out, preserving both the fastener head and the bit through repeated use. At 155 g, the bit remains easy to handle and store even though its larger cross section delivers the strength bigger jobs require.

Ideal for heavy equipment maintenance, commercial vehicle service, structural work, agricultural machinery, and any application where large metric hex fasteners are standard.
