Hex bolts are one of the most commonly used fasteners used in various industries such as construction, automotive, and manufacturing. They are widely used for securing heavy-duty machines and structures in place. When it comes to industrial applications, the fasteners used must be of the highest quality, especially since industrial processes can be demanding and unforgiving.
Stainless Steel Hex Bolts Vs. A307 Grade A Low Carbon Zinc-Plated Hex Bolts
There are two types of hex bolts commonly used in industrial applications. One is stainless steel hex bolts, and the other is A307 grade A low carbon zinc-plated hex bolts. The main difference between these two types of fasteners lies in their material construction.
Stainless steel bolts are made entirely of stainless steel, which is an alloy of steel, nickel, and chromium. Stainless steel bolts are known for their strength, durability, and resistance to corrosion, making them an excellent choice for harsh industrial environments. These bolts are ideal for applications that require a high level of hygiene and sanitation, such as the food and beverage industry.
A307 grade A low carbon zinc-plated hex bolts, on the other hand, are made of carbon steel and then coated with zinc to protect against corrosion. Although they are significantly cheaper than stainless steel bolts, they have a shorter lifespan and are not as strong or durable. Zinc plating can deteriorate over time, especially in harsh environments, leaving the bolt vulnerable to corrosion.
Stainless Steel Hex Bolts: Advantages and Disadvantages
Advantages
• High resistance to corrosion
• Suitable for use in harsh environments
• Extremely durable and long-lasting
• Easy to maintain and keep clean
• Available in a range of sizes and diameters
Disadvantages
• More expensive compared to other fasteners
• Difficult to cut and shape
• May react with certain materials that produce galvanic corrosion
A307 Grade A Low Carbon Zinc-Plated Hex Bolts: Advantages and Disadvantages
Advantages
• Significantly cheaper compared to stainless steel bolts
• Coated with zinc to protect against corrosion
• Widely available and easy to source
Disadvantages
• Not as durable or strong as stainless steel bolts
• Shorter lifespan compared to stainless steel bolts
• Zinc plating can deteriorate over time and leave the bolt vulnerable to corrosion.
When to Use Stainless Steel Hex Bolts
Stainless steel hex bolts are ideal for use in applications where hygiene, sanitation, and corrosion resistance are paramount. These fasteners are also suitable for use in harsh environments, such as offshore drilling platforms, chemical plants and refineries, and the food and beverage industry.
When to Use A307 Grade A Low Carbon Zinc-Plated Hex Bolts
A307 grade A low carbon zinc-plated hex bolts are suitable for use in applications where the cost is a significant factor. These fasteners are widely available and are suitable for use in less demanding environments, such as residential and commercial construction, where the risk of corrosion is relatively low.
Final Thoughts
Choosing the right type of hex bolt is essential when it comes to industrial applications. It is important to consider the environment and the requirements of the application before selecting a fastener. If hygiene and corrosion resistance are paramount, then stainless steel hex bolts are the ideal choice. If cost is a significant factor, then A307 grade A low carbon zinc-plated hex bolts may be a more suitable option. No matter what option you choose, make sure you are sourcing your fasteners from reputable suppliers to guarantee the highest quality materials.
