Hot Dip Galvanized Hexagon Nuts

There are many specific material grades for hot dip galvanized hexagon nuts. Different grades have different applications and different properties.

Common standards are things like ASTM A563,which includes grades like DH, DH3 for high strength. These often need extra carburization. Then there’s ASTM A194 Gr. 2H, a heavy hex nut made specifically for high-strength bolts.

These standards lay out the chemical makeup, mechanical properties (like hardness, proof load), and strict testing needs. It’s all to make sure they work as they should.

Correct installation

Correct installation of hot dip galvanized hexagon nuts allows the threads to be evenly stressed, stabilizes the structure, avoids damage to the coating and affects rust prevention, protects accessories, and reduces replacement costs.

They need to be tightened to a certain minimum amount of turning (that’s the turn-of-nut method). More often, you use torque wrenches that are calibrated or tensioning tools to get the exact tightness worked out by engineering calculations.

Putting hardened washers (ASTM F436) under the nut is a must. It helps spread out the load and keeps the nut from sinking into the material it’s connected to.

What is the level of customization or minimum order quantity (MOQ)?

For custom hot dip galvanized hexagon nuts,like specific grades, say ASTM A194 Gr 2H, or special coatings such as Xylan or Dacromet,the smallest number you have to order depends on how tricky they are to make and how we set up production.

Usually, you’ve got to order at least around 1,000 to 5,000. Though we can work with it if your project has specific needs. Just tell us the details of what you need, and we’ll give you the exact price and let you know how many you can actually order.
