5/8 IMP SCKT 3/8 DR DEEP

Fasten and remove heavy-duty bolts in restricted clearances with the Milwaukee 49-66-4428 SHOCKWAVE Impact Duty 3/8" Drive 5/8" Deep Well Socket. Engineered from proprietary heat-treated alloy steel, this rugged impact socket withstands extreme torque peaks while delivering up to 30X longer working life. Its slim thin-wall geometry allows smooth access into deeply recessed engine bays and mechanical compartments without compromising wall strength. Featuring a precision-machined 6-point deep well design, it contacts the flat faces of fasteners instead of the corners to prevent stripping and rounding under heavy impact cycling.

Key Features:

• Up to 30X Durability: Proprietary forged steel and controlled heat-treatment process withstand aggressive impact forces without cracking.

• Thin-Wall Profile: Delivers optimal exterior clearance to reach fasteners recessed in tight spaces.

• 6-Point Deep Well Grip: Engages bolt flats rather than corners to eliminate fastener rounding and slipping.

• Extended Reach Depth: Deep well profile easily clears protruding studs and extended threaded rod sections.

• Cordless Impact Ready: Engineered for maximum durability when paired with cordless 3/8" impact wrenches and high-torque drivers.
