Description

Hex nuts thread onto a bolt or rod to lock two pieces of material together, spreading the load evenly across the connection. Stainless steel hex nuts resist rust, so they hold up in rain, humidity, or salt air without the orange staining you get from standard zinc-plated hardware.

Match the nut size to your bolt diameter and thread pitch before you order, since the wrong thread won't seat properly. Stainless steel threaded fasteners are more prone to galling than some other materials. Always apply a suitable lubricant or anti-seize compound during assembly to help prevent the threads from seizing.

Product Features: 

  • Consistent sizing across the batch, so every nut threads on the same way, every time
  • Corrosion-resistant, stainless construction for outdoor, marine, and coastal projects
  • Fits a matching stainless steel bolt, or threaded rod
  • We carry coarse-thread nuts and bolts in diameters up to 1"
  • Available in Type 18-8 and 316 Stainless Steel
  • Sold individually, with savings on quantities of 100 or more

Make sure to pair stainless steel hexagonal nuts with corresponding stainless bolts, washers, and rod. Mixing stainless with other alloys like galvanized steel and zmax is not recommended, especially in coastal environments.

    Frequently Asked Questions

    What is your shipping policy?

    We ship anywhere in the United States with free shipping on qualifying orders of $250 or more. Orders are sent out Monday through Friday, excluding holidays. Check our Shipping Policy for complete details.

    Will this rust over time?

    No, a stainless hex nut resists rust far better than standard zinc-plated steel, making it a solid choice for outdoor and coastal projects. Choose 316 stainless steel for coastal, marine, or other highly corrosive conditions.

    Can I mix a stainless nut with a regular steel bolt?

    You can, but pairing stainless nuts with a stainless bolt or rod is the better choice. Mismatched metals can corrode faster than either would on its own.

    How can I help prevent stainless steel threads from seizing?

    Stainless steel fasteners can gall if friction builds during installation. Keep the threads clean, tighten at a slow and steady speed, and use an appropriate anti-seize lubricant when the application allows.

    Great Nuts!

    Good quality and excellent prices. I use these SS nuts for various projects on the farm. Whether it's a bolt for an exhaust on a tractor or a fence repair, these SS fasteners work great and don't rust. So I can take it apart years later if needed.
