PERFORMANCE TOOL 3/8" DRIVE 4MM HEX BIT SOCKET

This 3/8" drive hex bit socket features a 4mm hex size, forged from solid steel for good durability. The hex bit itself is integrated into the socket, making it a single, strong piece that's less likely to strip than a separate hex key. This design is particularly useful for working on applications where you need to reach fasteners in recessed areas or where space is limited, like certain engine components or interior trim pieces. The 3/8" drive size means it'll work with most standard ratchets and extensions you already have in your toolbox.

The solid steel construction means this socket can handle the torque needed for many common automotive tasks without bending or breaking. It's a straightforward, well-made tool that gets the job done when you need to turn a 4mm hex fastener. Keep this one handy for those jobs where a standard socket won't fit, but you still need the leverage of a ratchet.
