This 71-piece set of socket and hexagonal head tools includes various sizes such as hexagonal sockets and梅花 head tools, and is compatible with three drive interfaces: 1/4 inch, 3/8 inch， and 1/2 inch. It is equipped with a hard plastic toolbox for storage and is suitable for automotive repair， equipment maintenance， and home renovation repair scenarios. The entire set of tools is arranged by category， and each tool has a corresponding slot， making them neatly stored and easy to quickly find the required specifications. The toolbox has snap fasteners and a handle for carrying and storing the tools when going out.

The surfaces of the sockets and hexagonal heads have been treated， enabling them to fit with common ratchet wrenches and air wrenches， and to align with the force-bearing positions of bolts and nuts， making the disassembly and assembly process less prone to slipping. The set offers a wide range of specifications， covering common hexagonal and梅花 screws commonly used in daily maintenance. Whether for car maintenance， equipment disassembly and assembly， or hardware and furniture repair， most can find matching tools， reducing the hassle of frequent tool replacements.

Before use， confirm that the drive head， socket， and screw specifications are compatible. Then proceed with the disassembly and assembly operation. When using pneumatic tools， select the appropriate socket and do not overuse them for a long time to avoid tool deformation or cracking. Try to keep the force in the same axis and do not side-push to prevent damage to the socket or hexagonal head.

After each use， wipe the oil stains and iron filings off the surfaces of the sockets and hexagonal heads with a cloth， check if there are any obstructions in the tool slots， and clean them. Then place them back in the corresponding position. Tools should be stored in a dry environment to avoid long-term dampness and prevent rust on the metal surface. If there is resistance when turning， add a small amount of lubricating oil for maintenance.

Different drive interface specifications can be flexibly combined to meet the disassembly and assembly needs at different positions. The long sockets are suitable for deep spaces， and the short sockets are suitable for open areas. The entire set of tools is complete in specifications， suitable for repair professionals， automotive enthusiasts， or home backup. The regular storage box can also avoid scattered loss of tools， making it convenient and time-saving to organize. It is a very practical combination tool for maintenance operations.
