The DURATECH 12-Piece Combination Spanner Set is a professional-grade toolkit engineered for efficiency and durability. This metric open-end wrench set features the 12 most common sizes you need: 6, 7, 8, 9, 10, 11, 12, 13, 14, 17, 19, and 22 mm. Each wrench is forged from premium chrome vanadium steel for exceptional strength and treated with a matte chrome finish that is highly rust-resistant and resists dirt and grease.Designed for optimal performance, each wrench combines an open end with a 12-point offset ring end. The 15-degree angle offset provides crucial finger clearance and allows you to easily navigate around obstructions in tight spaces. The precision-machined 12-point box end ensures a secure grip on fasteners, drastically reducing the risk of slippage and preventing fastener round-off. Sizes are clearly stamped on both sides of the handle for quick and easy identification.To keep your workspace organized, the set comes with a durable storage pouch. Each slot is clearly marked with the wrench size, making it simple to find and put away the right tool. The convenient pouch protects your investment and can be easily hung or carried. Whether you're tackling DIY projects at home or handling basic auto repairs, this DIN 3113 compliant set is the reliable, high-quality choice that will save you time and get the job done right.
