Camshaft Sprocket Bolts

[D Wright]

Since I took this apart some time ago, Can't figure what bolts are needed to connect sprocket to camshaft. regular hex bolt or fancy (gonna get this wrong) torx or tri-square head bolt. Seems that I have three of theese (fancy) and can't remember where they go.
Thanks

The cam sprocket is originally held on by three 'fancy' tri-square cap screws. Torx have six 'corners' - Tri-square have 3 X 4 = 12
The head is very thin so the tri-square bit does not hold very well and can be easily stripped out. From memory, they can be replaced with standard Allen head, metric cap screws of the same diameter and lenght. Might have to cut the head of the Allen one down a bit thinner....
