Benefits of the Grey Pneumatic High Torque Drive: Transfers the pressure from the thinnest part of the socket wall toward the thicker section, resulting in increased strength. Allows up to 20% more torque to be applied than on standard hex impact sockets. The shift in pressure allows less socket wall thickness, increasing access to tight areas. Sockets grip the fastener across a broader contact area, reducing the chance of rounding off fasteners.
