Heavy hex nuts



Heavy hexagon (abbreviated to: hex) nuts are commonly used to fasten stud bolts or hexagon bolts within a pipe or flange fittings or for the fan housing of an air-cooled heat exchanger. At HBS we can supply nuts according to DIN/ISO or ASTM/ASME  in both imperial and metrics sizes. Some of the most common options:

Norm Unit of Measurement (size) Note  
DIN 933 / ISO 4032 Metric Height= 0,8mm  
DIN2510 NF Metric Nut with integrally washer  
ASME B18.2.2. Metric/Imperial Nut with integrally washer, Height = Diameter (H=D)

 *Please contact us, if you require a deviating norm for your nuts. 

All of our nuts are at least EN 10204-3.1. certified and are stamped with the logo of the manufacturer and the material identification code. Click here for all (alloy) material identification codes.
