Frequently Asked Questions

What are the key specifications for this hex nut, and what does 'Grade 8' mean?
This is a metric M30 hex nut made from carbon steel with a black oxide finish. 'Grade 8' indicates a high tensile strength of approximately 150,000 PSI, making it suitable for demanding, high-stress applications. The nut measures 1.181 inches across the flats.
What are the typical applications for a Grade 8, black oxide M30 hex nut?
This nut is designed for heavy-duty industrial and construction use, such as in structural steelwork, machinery assembly, and heavy equipment where high clamp load and corrosion resistance are required. The black oxide finish provides a basic layer of protection against rust in non-severe environments.
How is this product packaged, and what is the minimum order quantity?
The nuts are packaged in bulk quantities of 50 per bag or box. This pack size is designed for maintenance, repair, and operations (MRO) use, allowing you to purchase a practical quantity for ongoing projects without excess inventory.
