17pcs Impact E Torx Female Sockets Set — E5-E24 3/8'' & 1/2'' Drive

This is a dedicated impact socket set, engineered specifically for use with impact wrenches (electric, pneumatic or cordless). The CR-V steel is heat-treated to withstand high shock loads and torque without cracking or deforming. Regular (chrome-vanadium hand) sockets are not rated for impact use and may shatter under impact force. Always use these sockets only with impact tools—do not use them with hand ratchets or torque wrenches for high-torque applications, as the design prioritizes impact durability over precision hand use.

Yes, these sockets are fully compatible with electric, cordless and pneumatic impact wrenches/guns. The reinforced CR-V construction, heat treatment and black phosphate finish are optimized to handle the sudden, high-torque impacts produced by impact tools without rounding, splitting or failing. They perform well up to heavy-duty automotive, truck, machinery and industrial applications. Ensure your impact tool’s anvil size matches the drive (3/8" or 1/2") and always wear eye protection due to the high forces involved.

This set is E-Torx (external Torx / star sockets), designed to fit over external Torx bolt heads and external spline fasteners (commonly found on axle nuts, caliper bolts, suspension components, flywheels, crankshaft pulleys, etc.). It is not internal Torx (star-shaped holes). The E-Torx profile provides excellent grip on external star-pattern fasteners without cam-out. Standard internal Torx bits or sockets will not fit these external fasteners—use this set specifically where external E-Torx heads are present.

No, these impact sockets are highly resistant to cracking when used correctly. Premium CR-V steel with proper heat treatment and thickened walls make them much tougher than standard sockets. The black phosphate finish adds extra surface hardness and corrosion resistance. They are built to withstand repeated high-impact torque from impact guns. Cracking is rare unless severely misused (e.g., used on oversized fasteners, extreme side loading, or with a hammer/breaker bar far beyond rating). Always match socket size to fastener, avoid cross-threading, and never use damaged sockets.
