This set features a 72-tooth ratchet design, which makes it less likely to slip during operation and enhances work efficiency. The socket wrench set comes in three specifications: 13-piece, 17-piece, and 24-piece, suitable for bolts and nuts of different sizes. Additionally, the special wrench, also known as the ratchet wrench, should be used in conjunction with the socket wrench to tighten or loosen bolts and nuts in tight spaces, achieving assembly or disassembly without angle changes.
