The Tolsen 16558 is a deep socket designed for working with fasteners in tight or recessed areas where a standard socket cannot reach. Part of the Industrial line, this tool features a 1/2" drive and an 8mm size, crafted from chrome-vanadium steel with a chrome-plated finish to ensure durability and resistance to wear. One of its most practical advantages is an improved head profile, which allows you to grip and remove deformed or worn-out fasteners more effectively. This makes it a reliable choice for mechanics and technicians who frequently encounter damaged bolts in demanding industrial environments.
