It’s all in the name with this set. Sonic Tools 20-piece SAE deep socket set includes 6-point flank deep-well sockets from 3/8” to 1-1/4”. Sonic Sockets are made from Chrome Vanadium steel for a lifetime of durability, strength, and corrosion to resistance. The Flank Sockets have reliefs in the corners, allowing the socket to bite into the flats of the fastener, mitigating the chance of stripping.
