MILWAUKEE® Locking Extensions are built to deliver maximum control and secure socket retention—especially in tight applications. Designed with the largest knurling surface on both the shaft and the female drive end, they give you precise grip for hand-tightening fasteners and better handling when working with oily materials.

To keep sockets firmly in place, these extensions use a durable knurled locking collar, helping prevent drop-offs and interruptions mid-job. A detent hole increases engagement with the ratchet head for improved overall retention and a more secure connection while you work. Finished with chrome plating for corrosion and rust resistance, MILWAUKEE® Locking Extensions are made for long-term jobsite performance—and like all Milwaukee® Mechanics Hand Tools, they’re backed by a lifetime guarantee.
