Milwaukee 3/8" Drive 5mm Triple Square Bit Socket 45-34-1139

PRECISION FASTENING WITH ANTI-ROLL GEOMETRY

Engineered for high-torque applications where precision is non-negotiable, the Milwaukee 3/8" Drive 5mm Triple Square Bit Socket redefines the standard for mechanical fasteners. Unlike traditional two-piece bit sockets that are prone to separation under heavy load, this one-piece forged design ensures maximum energy transfer and long-term durability. The integration of FOUR FLAT™ sides provides a dual-purpose advantage: it prevents the tool from rolling away on uneven surfaces and allows for external wrench assistance when clearance for a ratchet head is restricted. This slim-profile architecture is critical for accessing recessed fasteners in tight engine bays or complex machinery where every millimeter counts.

• / FOUR FLAT™ Sides provide an anti-roll solution and wrench-compatibility for high-torque leverage in cramped quarters.
• / One-piece forged construction eliminates bit-to-socket separation, significantly extending the tool's service life.
• / Chrome-plated finish delivers superior resistance to rust and corrosion, maintaining integrity in harsh shop environments.
• / Laser-engraved size markings ensure rapid identification, even after years of heavy professional use.
• / Slim profile design offers optimized access to fasteners in obstructed or narrow work envelopes.
