Works with Grey Pneumatic's 1/2" sockets and socket sets
Features a friction ball, which is spring loaded steel ball that lines up with the socket retainer hole
Heat treated for strength and durability
Engineered specifically for use with impact tools, using the most up to date industrial specifications
Grey Pneumatic Impact Sockets are designed for professional tool users
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.
