            Flange nuts Classification


            Roughly divided into two flange nuts with locking teeth and the pattern of each part does not have staggered toothed cam, wedge design due to internal slope angle oblique angle is larger than the nut bolts, this combination will firmly bite into one overall surface contact, flange nut connecting member area, which determines its use. When vibration occurs locknut raised portions mutually dislocation, resulting in uplift tension to achieve the perfect anti-loosening effect. Flange nuts black surface treatment process, white zinc plated, blue zinc plated, color zinc plated.

            When the two parts connected bolt and nut in order to facilitate the connection, will usually screw holes or a member of a very large, so that the two parts will be very easy to find a positive, two pairs of holes not very accurate bolt connection can be achieved, bolt holes increase will inevitably lead ordinary nut member connected with the contact area is reduced, so that the use of this flange nut can avoid this situation.


            Basic standard flange nuts


            Effects or purposes: mostly used in the pipe connecting the nut or the need to increase the contact surface of the workpiece

            Material: A3 low carbon steel 35K high-speed steel wire 45 # steel 40CR 35Crmoa

            Hardness class: 4 Level 5 68 10 12

            Finish: color zinc plating and is generally divided into white zinc plating two kinds, and generally cold galvanized!

            Main specifications: M5 M6 M8 M10 M12 M16 M20 (M20 and M14 M18 above specifications flange nuts and more unusual)

            Thread size: Refer to GB nut thread

            GB Code: GB6177-2000
