Stainless Steel 316 Heavy Hex Nut

The SS 316 Heavy Hex Nut from Stainless Bolt Industries is a high-performance fastener designed to withstand corrosion and offer remarkable strength even under the most trying circumstances. Made of stainless steel 316, which contains molybdenum, this nut provides excellent resistance to pitting, crevice corrosion, and conditions that are high in chloride, such as those found in chemical processing and maritime settings. Its heavy hex design features a thicker and wider profile than traditional hex nuts, which increases its endurance and carrying capabilities under extreme stress conditions. Stainless Bolt Industries manufactures our SS 316 Heavy Hex Nuts in compliance with stringent international requirements, insuring toughness and long-term performance.

Overview of the SS 316 Heavy Hex Nut

Stainless Bolt Industries' SS 316 Heavy Hex Nut is a high-end fastening element designed for corrosive and high-stress situations. This nut, which is made of AISI 316 stainless steel, is perfect for offshore, chemical, pharmaceutical, and marine applications since it has been enhanced for corrosion resistance by the addition of copper. The heavy hex design has a broader and wider body than typical hex nuts, which improves load distribution and increases the surface area for wrench contact. Because of this, the SS 316 Heavy Hex Nut is particularly well-suited for assemblies with high pressure and vibration where joint stability is crucial.

Why Choose Our SS 316 Heavy Hex Nut?

We offer an extensive selection of SS 316 Heavy Hex Nut, designed to meet the diverse fastening needs of various industries. Here's why our SS 316 Heavy Hex Nut stand out :

  • Our nuts, which are made of stainless steel 316 with molybdenum added, offer excellent corrosion resistance in saltwater, acidic, and chemical-rich environments.
  • The heavy hex design's thick, broad profile ensures high carrying capability and reduced risk of thread stripping under stress.
  • Perfect for use in biological processing units, offshore platforms, marine environments, and power plants where safety and dependability are critical.
  • We provide a wide range of sizes, threads, and surface finishes (natural, passivated, and electro-polished) to suit your project-specific requirements.

Key Features of SS 316 Heavy Hex Nut

The stainless steel nuts provided by us are enriched with the following features.

  • Contains 2–3% molybdenum, giving it superior resistance to saltwater corrosion.
  • The heavier hex shape offers extra wrenching surface, improving grip during high-torque installation and reducing the risk of rounding or slippage.
  • Combines industrial-grade strength with sanitary-grade cleanliness, making it one of the few fasteners suitable for both chemical plants and clean environments like food or pharma industries.
  • Special finishing reduces the risk of galling (thread locking due to friction), which is common in stainless steel-to-stainless steel fastening.
