Milwaukee INSIDER™ Box Ratchet Metric Socket, 18mm

Milwaukee INSIDER™ Box Ratchet Metric Socket, 18mm

The 49-16-1618 Milwaukee INSIDER™ Box Ratchet Metric Socket is a specialized, low-profile socket designed to deliver unmatched access in tight spaces, especially when paired with the M12 FUEL™ INSIDER™ Box Ratchet. With a pass-through capable design and non-slip hex geometry, it grips fasteners securely while allowing you to work on longer bolts without bottoming out. Built for efficiency, it features dual-sided laser etching and a chamfered entry for quicker engagement—because tight spaces are hard enough without fighting your socket too.
