Flange Nuts

What is a Flange Nut and how are they used

Flange nuts have a wide flange under the hex that acts as a washer which helps to evenly distribute pressure over the parts being secured.

More information about Flange Nuts

• Flange nuts work extremely well for oversized or irregularly shaped holes since the flange will cover any discrepancies on the mating surface.
• Serrated flange nuts have serrations on the flange are positioned at an angle that bites into the material being fastened against to provent the nut from turning loose.
• Serrated lock nuts provides better vibration resistance than a standard hex nut.
• The serrations on the flange will scratch or mar a surface so if using on a painted or coated surface and moisture could be an issue, it is best to choose a fastener that will not run the risk of removing the coating and exposing the mating surface to the possibility of corrosion.
