5 point bolts?

[DASDAVID]

I just picked up a tc33, the plate reads tc33s, never heard of it . My question is what size are the injector hold down boolts, I have nothing to fit. The tractor starts and runs but is spitting out fuel at 1 injector just under the plate. Any help would be great.

There called penta bolts, obviously designed to be tamper resistant.size is measured from flat to opposite point, sockets are available
