The hexagonal socket is made of S2 steel, which has rigorous heat treatment and forging processes, with a hardness of up to HRC58, and has excellent toughness and durability. The surface is blue-treated to give it a metallic luster, which enhances its wear resistance, corrosion resistance, and rust resistance.This rugged, impact-grade tool is engineered to ensure accurate dimensions, and its solid drive shaft ensures a secure, reliable connection. The chamfered end of the hex bit socket allows for smooth insertion into the fastener head, reducing wear. Use with a ratchet wrench to tighten hex drive fasteners faster, and is good for working with parts in tight spaces.
