4mm Hex Key Bit Allen Socket, 10mm Shaft Hex Drive, 75mm Long, S2 Steel (Pack of 5)

Brief Overview

This pack of five 4mm hex key bits delivers reliable performance for precision fastening work requiring extended reach. The 10mm hex drive shaft integrates seamlessly with standard power tools and impact drivers, while the 75mm length positions the work point where you need it—ideal for countersunk applications and tight assembly configurations. If your shop frequently handles mixed fastener sizes, consider pairing these with 5mm hex bits and larger 6mm variants to cover the complete small-fastener spectrum.
