    I’ve learned over time not to get stuff made in China, because most of the time, the quality’s not great. And it’s the same story with these bolts. The first two I tried used up right away. I had to fall back on using the old trailer bolts, which, believe it or not, are 15 years old but worked perfectly well… So, just a heads-up, avoid Chinese bolts.

    I had to put in a little work to get them in there. They’re probably metric size or something, but I managed to make them fit.

    Good replacement good price

    Well, there’s not really much to tell, it’s just a bolt.

  5. RM

    Looks pretty decent. And they come with a regular lock nut, not a nylon lock nut.
