- National Bolt & Nut possesses a premium line of high-quality serrated flange nuts. The serrated flange of these fasteners offer superior gripping capabilities. And, along with our other premium flange nut products, our serrated flange nuts possess an enlarged circular base that more evenly distributes pressure over the part being secured. This circular base allows our serrated flange nuts to maintain a tighter hold.
- Because of the tight grip offered by the hardened locking serrations of our serrated flange nuts, no washer is necessary during application. Nylon inserts and nuts with patches are also available, which help prevent our hex flange nuts from loosening during vibration.
- Our serrated flange nuts meet dimensions per 145 with the addition of serrated teeth under flange.
- Other materials and finishes available. For further information, call or send an information request.
