Alright gearheads and DIYers, this 8-piece set of M12-1.75 hex flange nuts is exactly what you need for those projects where regular nuts just won't cut it.

The class 10 rating means these are serious hardware - they can handle significant torque and stress without stripping or failing.

The flange design eliminates the need for separate washers, saving you time and making installation quicker.

The prevailing torque top-locking feature is the real star here - it creates friction that helps prevent loosening from vibration, which is crucial for automotive, machinery, or any application where safety matters.

The zinc yellow finish provides solid corrosion resistance while making them easy to identify in your toolbox.

With an 18mm wrench size, they're substantial without being overly bulky.
