A NIKATTO set of 10 SAE (Society of Automotive Engineers) hex keys is a versatile and essential tool kit for various applications. These hex keys, also known as Allen keys, are L-shaped and come in different sizes, each with a hexagonal cross-section. The set typically includes key sizes ranging from the smallest 1/16 inch up to the largest 3/8 inch, incrementing in 1/16 inch steps. These hex keys are commonly used to tighten or loosen hexagonal socket screws and bolts. The L-shaped design provides leverage and allows easy access to screws in tight or hard-to-reach spaces. 
Whether you're a professional mechanic, DIY enthusiast, or general user, having a set of 10 SAE hex keys in your toolbox ensures you have the right size at hand whenever you encounter hexagonal fasteners in your projects or repairs.
