Metric High-Strength Steel Hex Nuts—Class 10
About 25% stronger than medium-strength steel nuts, these nuts are comparable in strength to Class 10.9 bolts.
Blue-dyed nuts have a distinctive blue color that makes them easy to distinguish from inch nuts.

Low-Strength Steel Thin Hex Nuts
Also known as jam nuts, these are about half the height of standard hex nuts. Use them in low-clearance applications or jam one against another nut to hold it in place. About half the strength of medium-strength steel thin nuts, use them for light duty fastening applications, such as securing access panels. Some of these screws meet ISO and DIN dimensional standards.
The distinctive coloring on blue-dyed steel nuts makes them easy to distinguish from inch-size nuts.
Nuts that meet ISO 4035 (formerly DIN 439B) adhere to international standards for dimensions and material composition to ensure compatibility with other products and tools. Although the DIN 439B standards are no longer active, they are commonly referenced globally.
