DIN 74361 Form "B" Narrow Flange Nut with Reduced Wrench Size
Smooth Flanged Bottom, Class 10 Steel

Also known as flat collar nuts or hexagon wheel nut with flat collar. These non-locking flange nuts are excellent for installation in tight spaces due to the small flange diameter and reduced wrench size. The smooth bottom flange acts as a built-in washer to evenly distribute force over a larger area against the fastening surface.

This non-serrated nut will not damage the threads of bolts or screws and can be reused. Also known as hex nut with integrated washer.

Material + Finishes
Hardened Class 10 metric flange nuts provide a high strength, high tensile fastening solution. Commonly paired with Class 10.9 metric bolts and screws.

These nuts are not coated or plated with a corrosion resistant finish.
