Heavy Hex Flat Nuts

Heavy hex flat nuts are usually made of carbon steel, stainless steel or alloy steel and are heat treated and surface treated to increase strength and corrosion resistance. It is designed to meet international standards, ensuring a match with bolts and other fasteners. Known for their stability and durability, these nuts are suitable for high strength and long-term use.Heavy hex flat nuts are made from different materials to fit where you’ll use them. Carbon steel ones are strong and work for most factory or machine jobs. Stainless steel types (like 304 or 316) don’t rust, so they’re good near saltwater or chemicals. If you need extra toughness, alloy steel nuts are treated to handle heavy use without wearing out. For really extreme stuff – like rockets or oil rigs – we’ve got titanium or Inconel options. Pick the material that matches your project, and these hex flat nuts will work well and last.

Detailed drawings and parameters

The size of heavy hex flat nuts (width and thickness) is made to match standard wrench tools, so you don’t have to guess if they’ll fit. The stainless steel ones (like 304 or 316) don’t rust easily, even in wet or salty places. These nuts follow safety rules like ASTM, ISO, and ASME – for example, carbon steel heavy hexagon flat nuts meet ASTM A563 DH specs, and stainless steel ones stick to ASTM F593. This means they’re the right size, strong enough, and made from the right stuff to work with bolts from any country. They also skip harmful chemicals (thanks to RoHS and REACH rules), so they’re safe for eco-friendly jobs. If you need nuts that pass safety and environmental checks, heavy hex flat nuts are built to handle heavy jobs without cutting corners.

FAQs

Q：Can heavy hex flat nuts be customized for non-standard sizes?

A：Yep, we can make heavy hex flat nuts in custom sizes if the standard ones (like M10 to M100 or 3/8” to 8”) don’t fit your project. Need a weird thread type (like UNC, UNF, or ISO) or a special coating? Just tell us – we’ll cut them exactly how you want. Even though they’re custom, we still check every batch to keep them within precise measurements. Whether it’s for planes, buildings, or custom machines, we’ll make heavy hex flat nuts that work for your setup. No extra fancy stuff, just nuts that do the job.
