Buyer Questions
Frequently asked questions
Are serrated flange nuts considered locking nuts?
They provide useful resistance to loosening on softer mating surfaces (mild steel, painted surfaces) where the serrations bite in, but they are not classified as 'prevailing-torque' locking nuts in the strict sense. For critical anti-vibration applications, use a nylon insert lock nut, all-metal locknut, or wedge-lock washer.
