The Tolsen 20058 is a compact 8-piece folding hex key set designed to keep all your essential Allen wrenches in one organized place. This tool includes eight different sizes, ranging from 1.5 mm to 8 mm, all crafted from heat-treated and chrome-plated chrome vanadium steel for lasting durability. Each key features a ball end, which is particularly helpful when you need to access bolts at an angle of up to 25 degrees, making it much easier to work in tight or awkward spaces. Measuring 13 cm in length and weighing 170 g, the set folds into a PVC handle with a rubberized grip that feels secure in your hand and doubles as a lever to provide extra torque. This portable design makes it a practical choice for anyone from home DIY enthusiasts to professional technicians who need a reliable, all-in-one solution for tightening and loosening hexagonal fasteners without carrying a bulky case.
