When it comes to high-temperature and corrosion-resistant applications, stainless steel 321 fasteners are a top choice. These fasteners are made from a titanium-stabilized version of 304 stainless steel, making them stronger and more reliable in tough environments.
In this blog, we’ll look at the different types of 321 stainless steel fasteners and where they are commonly used.
1. Bolts
321 SS bolts come in various shapes and sizes. They are used to hold two or more parts together. Common types include:
Hex bolts
U-bolts
Eye bolts
Stud bolts
These 321 stainless steel fasteners are strong, heat-resistant, and ideal for engines, machinery, and exhaust systems.
2. Nuts
Nuts are used along with bolts to secure materials. Common types of 321 SS nuts are:
Hex nuts
Lock nuts
Wing nuts
Dome nuts
They are known for their good grip and resistance to loosening even in high-vibration areas.
3. Washers
Washers are flat rings placed between the surface and the nut or bolt head. They help spread the load and reduce surface damage. Popular types include:
Flat washers
Spring washers
Lock washers
321 stainless steel fasteners like washers are used in piping, engines, and industrial tools.
4. Screws
Screws are another important type of fastener. They are mostly used in assemblies where threading is required. Common types include:
Machine screws
Self-tapping screws
Socket head screws
Pan head screws
These 321 SS fasteners are used in applications where strength and corrosion resistance are needed.
5. Studs
Studs are threaded rods without a head. They are used in flanged joints and equipment with high pressure and temperature. 321 stainless steel studs are reliable in industries like petrochemical and power plants.
6. Threaded Rods
Threaded rods are long rods that are fully threaded. These fasteners are helpful in construction, support systems, and industrial machines.
