The socket-plus-wrench combination covers most repair scenarios.
Q2: What material is used? How much torque can it handle?
A: Both sockets and wrenches are forged from premium chrome vanadium steel (Cr-V) with quenching and tempering heat treatment, reaching HRC 48-52 hardness. Torque performance far exceeds national standards, making it suitable for heavy-duty applications like professional auto repair and heavy machinery maintenance.

Q3: What’s the difference between spark plug sockets and regular sockets?
A: Spark plug sockets have a rubber protective ring inside that grips the spark plug insulator during installation and removal, preventing the ceramic portion from cracking. The inner depth is also sized to fit spark plugs for precise positioning. Regular sockets lack this protection and are not suitable for spark plug service.

Q4: What is the universal joint used for?
A: A universal joint allows angular offset between the socket and the fastener, ideal for confined spaces where straight access isn’t possible — such as inside engine bays or deep within chassis components. It flexibly adjusts the working angle to improve efficiency.

Q5: How is this different from other 40-piece sets?
A: The key feature of this set is the combined socket + 14 combination wrench configuration. Unlike standard socket sets, it includes a full range of combination wrenches for tight spaces where sockets can’t reach — making it more practical. Note: This product is being discontinued, available while stocks last.
