This is a follow-up question to Seized nut & bolt - difficult to access

What happened - or what did I do wrong - for this bolt to lose its thread in this way?

Is it simply doing it up too tightly? Is that all it is?

Bolt with worn thread


It looks to me like it has been over-tightened, beyond the point of failure of the bolt.

    I would completely agree. Looks like the bolt, while pretty was probably a cheap grade 1 bolt which couldn't handle any kind of torque, might have been the nut, or probably a combination of the two. – Pᴀᴜʟsᴛᴇʀ2 Apr 4 '16 at 16:12

    Yeah, I've done that. Another proud moment. – DucatiKiller Apr 4 '16 at 16:48
