Working on hybrid or electric vehicles demands tools you can trust with your life literally. Exposed fasteners on high-voltage systems carry real risk of fatal electric shock, and standard socket sets offer zero protection. The Sealey AK7942 is a 9-piece 3/8" square drive insulated socket set built specifically for this environment. Every component is fully insulated to VDE and EN 60900 standards, protecting against electric shocks up to 1500V DC and 1000V AC, making it equally suited to HV automotive work and electrical trades such as electricians and carpenters. Sockets are manufactured from hardened and tempered Chrome Vanadium steel and cover the most commonly needed sizes: 8, 10, 12, 13, 14, 17, and 19mm. The set includes a flip reverse comfort grip ratchet wrench with push-button quick release and a 100mm extension bar, giving you the reach and convenience needed in tight engine bays. Backed by a lifetime guarantee and supplied in a storage case, this set is part of Sealey's comp
