Anti-Slip Tooth Design: The anti-slip tooth design of the ratchet keeps the wrench head tight, preventing slipping and swinging, and increases anti-slip performance by 30%. Even if the fastener becomes rounded due to long-term wear, the ratchet wrench can still tighten it, making it more effective than most ratchet wrenches you have used before Efficient Wrench: The 72-tooth ratchet on the box end is smooth and requires only a 5-degree working swing arc, allowing it to rotate in limited spaces and achieve simple and fast operation. The 180-degree flexible head helps you reach narrow spaces that most ratchet wrenches cannot, making the operation easy High-Quality Stubby Wrench Set: The flexible head ratchet combination set is made of high-quality chrome vanadium steel. It has undergone heat treatment to achieve maximum strength, and the additional black electroplating coating improves surface corrosion resistance, effectively prolonging its service life Metric Size Easy to Carry: The 8-piece wrench set includes sizes 8, 10, 11, 12, 13, 14, 15, and 17mm to meet most of your needs. The ratchet wrench set comes with a premium rolling pouch, and each wrench storage slot is marked with the corresponding wrench size to keep all wrenches organized for easy carry and storage Wide Application: Its superior design makes it widely applicable for fastening or loosening nuts and bolts in many narrow spaces. It can be used for home maintenance, mechanic repair, auto bicycle repair Product Description WIDE APPLICATIONS
