Tips for choosing Nut:
*Make sure that you use a nut designed with greater strength than the bolt. Because a weaker nut and stronger bolt results in fastener failure.
*Always choose a nut finished to match the bolt. For example, hot dip galvanized hex bolts need to be joined with hot dip galvanized nuts, and correspondingly, with hot dip galvanized washers.
