Genius Tools SAE Jumbo Impact Sockets 3-1/2" Dr. (7" - 9-1/4")
For the largest inch-sized fasteners in industry, Genius Tools offers SAE Jumbo Impact Sockets with a 3-1/2 inch square drive from 7 inch to 9-1/4 inch. They are intended for equipment such as large presses, turbines, ship machinery and mining plant.
The series lists thirty-seven sizes in 1/16 inch steps, so the socket can be matched exactly to the fastener. Lengths increase from 230mm to 275mm, giving full contact on the tall nuts typical at this scale.
Each socket is made of Chrome Molybdenum Steel and uses a 6-point opening that contacts the flats of the hex. This is the preferred layout for impact work because it delivers torque evenly and reduces the risk of damaging a very expensive fastener.
Smaller sizes in the same drive, from 4-1/8 inch, are in the companion series. Sockets with a drive size of 2-1/2 inch or higher are not stock items and will be custom ordered, so please allow lead times of up to 60 days.
