Stainless Steel Nut Manufacturer in India

Top Manufacturer of SS Hex Nuts in India, At Resonable Cost


Stainless Steel Nut


There are ASME, ASTM, DIN and other international standards that govern the nut sizes. The 3/4 Hex Nuts are some of the most commonly used nut sizes which is a medium size. The materials grade is chosen in aspects of the corrosion resistance, strength, wear and tear resistance and cost of the material.The supplied Alloy 304 Stainless Steel Hex Nuts are one of the cheapest nuts to be purchased in the market having good strength and excellent corrosion resistance. However, there are other material grades that can stand better corrosion resistance compared to steel.

The use of 304 Stainless Steel Slotted Hex Nuts is limited to less corrosive applications. For applications that need more resistance to salty air or chloride ion stress corrosion cracking, the 316 SS Hex Nuts are better. They are used in sea water, marine and other corrosive applications. Regal Sales Corporation is a leading manufacturer of hex nuts and Heavy Hex Nuts in different material grades, specifications and standards. Please feel free to contact us for more information and pricing of the Stainless steel metric hex nuts in various standards, dimensions and material grades.

Are Stainless Steel Nuts Magnetic?


  • ➤ SS 304 and SS 316  are mostly non-magnetic, though cold working can make them slightly magnetic.
  • ➤ SS 410 and SS 430 are magnetic.

Are There Any Disadvantages to Using Stainless Steel Nuts?


Disadvantage Description
Cost Higher than carbon or alloy steel.
Galling/Seizing Prone to thread locking with stainless bolts; lubricants may help.
Strength Weaker than high-tensile steel for heavy loads.
Thermal Expansion Expands/contracts with temperature, affecting joint integrity.
Chloride Sensitivity Susceptible to corrosion in salty or chloride-rich environments.
Magnetism Some grades can become magnetic after cold work.
