Talk:Spline drive
From Wikipedia, the free encyclopedia
[edit] Exactly what is spline drive?
So are you saying that spline drive is different from Triple square or double hex? All appear to be 12-point fasteners.
Can you provide a better reference to a description and standard sizes than some commercial web site?
Of course this spline drive is different from spline drive sockets.
There is also a recent spline drive intended for bolts that will fit 6-point hex, 12-point (double hex), square, E-Torx, and spline bolts. A number of American comapnies are offering this drive, including SK, Mac, and Proto.
