I have a brand new 2018 Ford Transit cargo van that came without a passenger seat; the van was ordered as a fleet vehicle for some purpose that didn't require a front passenger seat. I'm now installing a factory seat.
What I have are four holes in the floor of the van into which I will bolt my seat base. However, there are no threads in those holes. I assume the hardware here is higher that average in terms of strength, but I've ordered the bolts from Ford so I;m not concerned about choosing the wrong grade/type of bolt.
I'm trying to understand all the parameters of doing the tapping correctly. One thing I'm struggling with is the tap selection. I've read that the different metals that the taps themselves are made from determines the hardness of materials they can perform their function against.
So, how can I determine the correct tap to purchase? Again, I'm not looking for sizing or anything like that ... more quality or functional match to the thing I'm tapping, the floor of my van.
