I bought a pair of tie rod ends online because you can't buy anything here. They arrived yesterday and I only then noticed they're left hand threaded. Made a few phone calls only to discover no one sells nuts that will fit around here. So off to the hardware store and picked up a die. It was M8 threaded originally so I went with 1/4" to ensure there'd be lots of thread, didn't want the old threads cutting across. The piece is zinc and now that I'm looking at how thin it is I'm worried about the strength. All the force on it should go up or down the length, right? Is it strong enough?
