VESSEL BH-40 Double-Headed Socket, Opposite Side 8 + 2 Bit Joint 4-Way

Many drilling screws (hex heads) are used in construction of shingling and siding boards. In these operations, many sizes of sockets were required for installation such as multiple nut setters (8 opposite sides) to fit the size of the drill screws, and anchors for hollow walls (0.4 inch (10 mm) opposite sides). Double head sockets can also be used as an adapter to extend the bit, making it convenient for you to carry many tools and socket bits in the field. 4 in 1 Can be used as a double head bit + socket (8 opposite sides/9.6) + extension joint. It locks securely into the bit, so you can tighten the screws. For siding, tightening roof drill screws, extending driver bits, and extending drill bits. Socket: Both heads: 3.1 / 3.8 inches (8 / 9.6 mm), total length 2.4 inches (60 mm), diameter 0.7 inches (18 mm)
