NC in the context of bolts can have several meanings, depending on the specific application or industry. Here are a few common interpretations:
- Non-corrosive: This refers to a bolt made from materials that are resistant to corrosion, such as stainless steel or nickel alloys.
- Non-critical: This designates a bolt that is not essential for the structural integrity of a system or component.
- Nominal diameter: This refers to the diameter of the bolt head and nut, as opposed to the actual diameter of the bolt shank.
For a more precise understanding, it's essential to consider the context in which the term "NC" is used. For example, if you are looking at a bolt specification sheet, "NC" might refer to the thread class or the material grade.
It's always best to consult the relevant documentation or a specialist for clarity.
