This Sealey Premier impact socket set is designed for professional mechanics and serious DIYers who require durable, high-performance tools for heavy-duty applications. Its primary benefit is the robust construction and WallDrive® system, ensuring longevity and superior grip, even under high torque. A potential caveat is its size range, which may not cover every specialized bolt head. This 8-piece set includes essential large-diameter sockets, manufactured from Chrome Molybdenum steel with a manganese phosphate finish for corrosion resistance and suitability for impact wrenches. It comes supplied in a convenient storage case.

Impact grade sockets are manufactured from higher-strength steel (like Chrome Molybdenum) and have a specific heat treatment process to withstand the shock and vibration associated with impact wrenches, unlike standard chrome vanadium sockets.
The WallDrive® system grips the fastener on its flat sides, not the corners. This distributes the force more evenly, reducing the risk of rounding off bolt heads and allowing for higher torque to be applied safely.
While you can physically attach them to a 3/4"" drive ratchet or breaker bar, these sockets are specifically designed and optimized for the high-torque, high-impact forces generated by air or electric impact wrenches. Using them with a standard ratchet might be less efficient for heavy-duty tasks.
The sockets are manufactured from hardened and tempered Chrome Molybdenum steel.
The manganese phosphate finish provides inherent corrosion resistance. Simple cleaning with a dry or slightly damp cloth after use and storing in the provided case in a dry environment is usually sufficient for maintenance.
The set includes the following metric sizes: 24mm, 27mm, 29mm, 30mm, 32mm, 35mm, 36mm, and 38mm.
Yes, the Sealey Premier range is designed for daily professional use, indicating they are built to withstand the demands of a professional workshop environment.
Verify you are using the correct metric size. Ensure the fastener head is not excessively worn or damaged. Check that the socket's WallDrive® feature is properly engaging the flats of the fastener.
Ensure the socket is fully seated. Try applying torque more steadily rather than relying solely on rapid impact. For extremely stubborn fasteners, consider using a penetrating oil.
Discontinue use immediately. This indicates the socket may be under excessive stress for its intended use or has a defect. Contact Sealey for warranty information if applicable.
Confirm you are using a 3/4"" square drive tool. Ensure the drive mechanism on both the tool and socket are clean and free of debris. Check that the retaining ball or pin mechanism on your tool is functioning correctly.
Setup: No specific setup is required beyond selecting the appropriate socket size for the fastener. Ensure the socket is fully seated on the fastener head and the drive tool (impact wrench or breaker bar) is securely attached to the socket's 3/4"" square drive.
Compatibility: This set is designed for use with 3/4"" square drive impact wrenches and breaker bars. It is compatible with standard 3/4"" drive accessories. The sockets are impact grade, meaning they are built to withstand the forces generated by power tools.
Care: To maintain longevity and performance:
