Spanner Sockets
For easy tightening and loosening, these sockets have pins that grip the slotted sides on bearing nuts. These sockets require less clearance around bearings than standard hook spanner wrenches, so they’re good in tight spaces. Use them with a square-drive wrench handle or a ratchet wrench; they’re not for use with impact wrenches.

6-Point Impact Sockets
Achieve the best possible grip on hex fasteners and prevent rounding. These sockets are made to withstand the high torque and force of impact tools.
3/4", 1", and 1 1/2" square drive size sockets require a locking retainer. Use with an impact wrench that has a pin-style socket retainer, or use a socket retaining ring with tools that have a hole- or hole-and-ring style socket retainer.
