This high-quality mechanic tool set is crafted from premium carbon steel, ensuring exceptional wear resistance and strength for superior performance. The product features a superb plating process that enhances its gloss, hardness, and corrosion resistance, contributing to both durability and aesthetic appeal. Designed for convenience and efficiency, the thin walls of the sockets fit easily into tight spaces. The drive's rounded inner corner design provides a stronger locking force, preventing slippage and facilitating easier assembly and disassembly. Sockets are securely locked to the ratchet shank via stop balls and locking pins, preventing accidental detachment. The universal joint offers flexibility and reliability, with a maximum bending angle of nearly 90°, allowing for easy adjustments in confined areas. Its spring-locking ball ensures the universal joint remains firmly engaged with the socket or extension rod, offering enhanced reliability and reducing the risk of detachment during use. Each extension rod is equipped with a steel post for effortless fastener loosening, and extension rods with spring-loaded retaining balls securely hold sockets in place for safer and easier operation.
