With a splined profile on one end, these shafts transmit high rotational loads—good for hydraulic systems, machine tools, and other high-torque applications. Compared to keyed shafts, they last longer, handle higher torque, and do not require as tight of a fit.

Grooved on the inside, these bearings rotate with your spline shaft as they move loads up and down its length.

For use with splined shafts, which are commonly found in gearboxes and pumps, these couplings are capable of transmitting more torque than couplings for round and keyed shafts.

Also known as Bristol bits, these have a knurled-end shank that allows finger tightening. They can also be used with the included screwdriver.

Sets include an assortment of keys. These simple tools turn fasteners from either end and reach into tight spots.

Adapt your rotary hammer to fit a variety of masonry drill bit shank types.
