Frequently Asked Questions

What are the key specifications for this hex nut, and how does the metric thread size relate to Imperial fasteners?
This is a Grade 8 carbon steel nut with a black oxide finish. It has a metric fine thread size of M16 x 1.5, which corresponds to a nominal bolt diameter of approximately 0.630 inches, and a width across flats of 0.945 inches for standard wrench compatibility.
What are the typical applications for a Grade 8, fine thread nut like this?
Grade 8 fine thread nuts are designed for high-strength, precision applications where vibration resistance is critical, such as in heavy machinery, automotive assemblies, and structural frameworks. The fine thread provides a tighter clamping force and is less prone to loosening under dynamic loads compared to coarse threads.
How are these nuts packaged for order, and what is the minimum quantity?
These nuts are packaged in bulk boxes of 500 pieces. This industrial pack size is standard for B2B orders to support production or maintenance operations, ensuring you have an adequate supply for your project needs.
