3/8 in. and 1/2 in. Drive Impact Accessory Set (10-Piece)

Overview

When you're running an impact wrench, the right adapters and extensions are what turn one tool into ten. The DEWALT DWMT74741 3/8 in. and 1/2 in. Drive Impact Accessory Set gives you the drive adapters, extensions, and universal joints to reach recessed fasteners, step between drive sizes, and keep an impact gun working where a standard socket won't fit. It's the kind of kit that lives in the truck box and earns its keep on brake jobs, suspension work, and anything bolted down tight.

Key Features

• Resists rust and corrosion in the field — black oxide finish stands up to shop moisture and outdoor use.
• Runs safely on impact tools — all pieces are impact-rated, so you can drive them with an impact wrench without cracking chrome accessories.
• Bridges drive sizes on the fly — includes both 3/8 in. and 1/2 in. drive adapters so one socket collection covers more guns.
• Reaches deep, recessed fasteners — extension bars extend your drive line into tight engine bays and wheel wells.
• Gets to fasteners at an angle — universal joint lets the impact swivel around obstructions.
• Stays organized and portable — durable molded case protects the pieces and interlocks with other DEWALT cases for stackable storage.
• Impact-adjusting adapter — steps drive sizes up or down for maximum flexibility on the job.
• 10 pieces cover the common gaps — a compact, focused kit rather than a bulky set of duplicates.

The adapters let you run 3/8 in. sockets on a 1/2 in. gun and vice versa. Pair with any impact-rated socket set; do not use with chrome (non-impact) sockets on high-torque tools.
