You can strip the threads on the nut or the bolt and both can warp because of over torquing.

Extreme overtorque can cause the bolt to endure tensile stretch beyond safe limits, damaging the microstructure of the metal in the bolt and cause chrystallization of the metal in the bolt, especially under continued stress and vibration such as in a vehicle wheel bolt. This can cause the bolts to break off, which can be fatal at high speed. Wheel bolts over-torqued 50% or more should be replaced immediately by a mechanic. Always tighten wheel nuts with a torque wrench. Also, the nuts may be impossible to remove by hand if you have a flat.

If you over torque a wheel lug nut for example, if you have a flat you won't get the wheel off. If over torque a bolt you could stretch the bolt, round the head, damage the assembly, or break the bolt head completely off.

There are a number of possibilities. You can strip the threads on the nut, or the bolt. You can snap the bolt off. You can damage whatever the nut and bold is holding (especially if it is plastic, or a gasket - head gaskets and cam/rocker cover gaskets are especially prone to this), or you can weaken the nut or bolt so that it doesn't hold strongly anymore (had this myself once - brass wheel lugs on a classic Mini. They went on, but didn't stay on. It's kinda scary when you brake for a corner, and one of your wheels passes you!)
How much it will affect you depends on what the nut and bold are holding, and how much they were overtightened.
Good luck!

over torquing a nut or bolt, you could break something important, what ever you over torque may just stick on you... cast iron breaks pretty easily...

warp the components,put too much stress on the nuts or bolts will cause them to break or damage the threads

You can also stretch the bolt or strip the threads out of the hole.

The head can break off or the corners of the hex head can get rounded off or ''stripped''! This can happen with screws as well.

you can either strip the threads out or break the bolt.

Apart from what the others said, you can damage the gasket and/or the part that you are assembling.
