The M10 cap head screw (hex bolt) has a hexagonal head driven by a wrench, while the M10 socket cap screw has a cylindrical head with an internal hex drive (Allen key). Socket cap screws are preferred for compact designs where space is limited, while hex cap screws allow higher torque with external tools.
