Grey Pneumatic 1/2″ Drive 19 Pc. Standard Length Fractional Master Set

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 the socket wall thickness to be reduced increasing access to tight areas. Grip the fastener across a broader area reducing the chance of rounding off fasteners.
