classic dominator siding screws
Attempting to replace fenders on a Classic Dominator trailer and found the screws to be in between 1.5 and 2.0 torx bits, I have several sets of bits and nothing between these two sizes nor does McMaster Carr supply show anything in the middle. Any ideas?
Thanks Jimmy Parker |

Re: classic dominator siding screws
Jimmy the screws on both of my Classic trailers have been double square. Square bits work fine, sorry but cant remember what they call the size.

Re: classic dominator siding screws
It is not a torx bit, I have a classic trailer and as the other guys have pointed out a square bit is all you need. In the hardware store like HD, deck screws have single square heads. That is the bit that you need.

Thanks for the help, a #2 square did the job although it didn't make sense to me!!

They use that style of drive because you can drive the screw in from an odd angle and also they do not strip out the square drive area like a Phillips drive will. FES 387

Re: classic dominator siding screws
That screw head was designed by a Canadian named Robertson somewhere in the 1950's. Four sizes matched to a colour. Smallest being yellow, then green, red and black. Never got popular in the States but they really work well, stay on the end of your driver bit and don't strip easily.

Re: classic dominator siding screws
We saw a lot of them in the marine industry in late 50s and the sixtys. Good fastener, lots better than a phillips. Still see them a lot in the electrical industry.
