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.
