Japanese Nitto Seiko Develops Share Cross Drive Recess for Bits of Similar Sizes

In manual fastening and loosening of screws at construction sites and other workplaces, it is time-consuming to change bits for each screw drive recess, which causes users to disassemble and assemble with a bit that does not fit the recess, thus resulting in a collapsed recess.
To solve this problem, Nitto Seiko has developed a "Share Cross" that can be used with bits of similar sizes. "Share Cross" can be suited for various types of fastening and improves work efficiency in manufacturing operations.
"Share Cross" is a small cross-recess with another large cross-recess superimposed on it, so that bits of similar sizes (e.g., #2 or # 3) can be used on the same screw head recess. The structure is such that the drive surfaces for transmitting torque can be shared, which achieves the optimum fit of the bit and maximizes the performance.
