Editor's Pick: Whether you're fixing furniture or assembling a bike, not having a handy set of hex keys on hand is truly frustrating. This set covers both SAE and metric, with 17 sizes ranging from 5/64 inch to 8mm. Each key opens independently up to 270 degrees, so it's easy to turn in tight spaces. The tips feature a square-cut design that fits snugly into screw slots and resists slipping and stripping. Made from heat-treated alloy steel with a rust-resistant coating, and the nylon handle provides a steady grip. When folded, it's about the size of your palm, so it takes up little space in a tool bag or drawer corner.
