PM Metal provides guidelines with respect to fastener patterns and spacing to prevent this problem. Protect legibility of markings Minimize exterior dimensional changes Maintain thread fit Chemical Composition Both 2H and 2HM nuts have the same chemical composition. Grade 5 steels are produced from unalloyed medium carbon groups, such asym typeand are usually work-hardened to improve their strength.

Leave this field empty.

These steels are typically medium carbon alloys, such as types and Trade is the most common grade used in automotive applications. Grades 2, 5, and 8 are typically the standard for carbon steel screws and bolts, with alloyed carbon steel being a higher-end variation on these metals.
