Flanged Hexagon Nuts
Serrated flange nuts, also known as flange head nuts are available in a variety of diameters at competitive prices. When you need a firmer hold the flange nut will be ideal. The increased holding ability of these nuts is due to the serrated flanged base of the nut. This is specifically designed to spread the load over a slightly wider surface area. This allows for a firmer hold, whilst exerting less pressure on the material and reduces the need for the use of a washer.
Available in A2 stainless steel and steel covered in bright zinc plating (BZP)
For additional holding power combine the nut with one of our flanged hex bolts.
