Frequently Asked Questions

What are the key specifications for these hex nuts, and what does 'Grade 6' mean for performance?
These are M30 metric thread hex nuts made from carbon steel with a zinc-plated finish for corrosion resistance. 'Grade 6' indicates a medium-duty strength class with a minimum proof load of approximately 90,000 PSI, suitable for general structural and industrial fastening applications.
What are the typical applications or use cases for these M30, Grade 6 hex nuts?
These nuts are designed for medium-duty bolting in construction, machinery assembly, and structural frameworks. Their 1.181-inch width across flats allows for standard wrenching and they are commonly paired with Grade 5 or similar bolts to secure large components, flanges, or heavy equipment where high tensile strength is not the primary requirement.
How are these nuts packaged for order, and what is the minimum quantity?
The nuts are packaged in bulk boxes of 100 units per box. Orders are typically placed by the box, ensuring you receive a complete, counted quantity for inventory and project planning.
