Flange nuts sometimes have rotating flanges that help to form a more stable structure without affecting the finished product as serrated flange nuts do. Rotary flange nuts are mainly used to join wood and plastics. Sometimes both sides of the nut are serrated, allowing either side to be locked.

Self-aligning nuts have convex, spherical flanges that fit with concave disc washers to allow the nut to be tightened on surfaces not perpendicular to the nut.

Hex flange nut mainly comprises a nut body, a flange face is fixed on one end of the nut body, and a cap is fixed on the other end of the nut body. It has good sealing and corrosion resistance.

Hex flange nut mainly comprises a nut body, one end of the nut body is fixed with a flange face, the other end of the nut body is fixed with a cap; As a result of the nut body is set on the cap, so in the use of hexagonal flange nut has a good sealing, can effectively prevent rain, moisture, dust and other harmful substances immersed in the nut body, prevent corrosion phenomenon of the nut body, thus can greatly extend the service life of hexagonal flange nut.
