Buying Guide

Choose the right drive size

A 1/2-inch drive is standard for most construction fasteners; confirm drive size fits your sockets and torque needs

Prioritize torque for heavy fasteners

Look at reported peak torque (e.g., several hundred to around 1,000 ft-lbs) to ensure the tool can break and tighten lug nuts and structural bolts

Cordless vs corded for job-site mobility

Cordless impact wrenches give portability for site work—verify battery compatibility and whether tools are sold as bare tools or with accessories

Motor type and long-term reliability

Brushless motors typically offer better efficiency and lifespan under continuous construction use compared with brushed motors

Check included accessories and value

Some models include socket sets or come as bare tools; factor included sockets and accessories into overall value for the job
