1" Drive Jumbo Impact Sockets Set Metric Extension Cr-Mo 6-Point, 21-Piece Set

Built for modern and imported equipment that uses oversized metric fasteners, this 1" drive metric jumbo impact socket set is made for serious industrial work. It supports heavy-duty automotive, agricultural, and construction applications. Each socket is made from heat-treated chrome molybdenum (Cr-Mo) steel for strength and long service life.

Because oversized fasteners require extreme torque, this impact socket set uses a 6-point design that grips the flat sides of fasteners. As a result, it delivers higher torque while reducing the risk of rounding. The set also includes a heavy-duty ratchet, extensions, and a sliding T-bar for added reach and control.

Impact Socket Set Applications

Applications and use:

This socket set is commonly used on heavy equipment, fleet vehicles, agricultural machinery, and industrial fasteners. Because metric jumbo fasteners require extreme torque, a 1 inch drive system is often the correct choice. As a result, this set works well for suspension work, axle nuts, drivetrain service, and structural fasteners.

Why a 1 inch drive impact socket set matters:

Standard socket sets cannot safely handle oversized fasteners. For this reason, a 1 inch drive impact socket set spreads torque across a larger contact area. This reduces tool stress and improves control during high-torque applications. In addition, the deeper socket design allows access to recessed fasteners found on modern equipment.

Socket dimensions and torque guidelines align with commonly accepted industry standards such as ANSI specifications.
