Fasteners are the apparatus helpful to join, fasten, or assemble two or more surfaces. Fasteners include screws, nuts, bolts, flanges, values, and rivets. Fasteners are highly versatile, making them useful in numerous domestic and industrial applications.

Incoloy 825 is a nickel-iron-chromium alloy. It provides good oxidation-corrosion resistance in elevated temperature areas. Also, it exhibits good mechanical properties, making it beneficial in high-acidic environments.

Incoloy 825 enhances the performance, connectivity, and durability of the fasteners in high-temperature surroundings. It provides outstanding resistance to pitting, cracking, and intercrystalline corrosions. Thus, making it tough and unbreakable in hostile environments.

Mangalam Metal Corporation offers exclusive grades of Incoloy 825 Fasteners to our clients across the globe. We use high-quality raw materials to produce our Incoloy products to meet national and international standards.


Fasteners are easy to install or upgrade. In industrial premises, we generally use three types of fasteners. They are stainless steel, carbon steel, and alloy steel. To enhance the performance and stability of fasteners in high-temperature areas, we use Incoloy 825 coatings.

Selecting a proper Incoloy Fastener is a very crucial decision. One should consider the following factors before installing them:

  • Working Surroundings
  • Installation Process
  • Convenience
  • Adjacent Elements
  • Weight Restrictions

In general, we use the 9-basic type of fasteners in industrial premises. However, we are listing down 4-important Incoloy 825 Fasteners that are always in demand and recommended.


Incoloy 825 Nuts are circular ring-shaped components with internal threads. Before manufacturing them, we take a precise measurement of their malting bolt. The most popular nuts include hex, locks, jam, coupling, square, and axle.

Incoloy 825 Bolts are long cylindrical-shaped rods with external threads. We produce bolts with accurate measurements prescribed within the ASME schedules. The most popular bolts include hex-head, U-bolt, lag, carriage, and eye-bolt.


Incoloy 825 Washers are ring-shaped discs having a large opening in the center. These washers are added in-between the nuts and bolt to provide extra strength under high pressure and turbulence. Also, they offer extra grip to these fasteners to evenly distribute the stress over the material’s surface.

The most popular washers include plain, spring, beveled, and locking washers.


Incoloy 825 Rivets looks more like a bolt but without the threads. It resembles a long cylindrical shaft with a head on one side and its tail on the other. The rivet is helpful to create permanent joints between the two surfaces and offer resistance against shear forces simultaneously. It exhibits magnificent performance in heat-generating applications.

The most popular rivets include blind rivets, pop rivets, semi-tubular rivets, large flange rivets, and solid rivets.


Incoloy 825 Anchors represent an injection. We install them to connect structural or non-structural elements in high-temperature areas. These anchors embed themselves in the materials and hold the materials tightly. The anchor can handle high-stress and shear forces in given applications.

The most popular anchors include internally threaded, externally threaded, acoustical wedge, masonry, bonded, screw, and pin anchors.

Markings and Packing

Product packaging serves to protect the products inside. Mangalam Metal Corporation effectively ensures all the products are deliverable to our clients securely. In the case of exports, we follow all international standard protocols of packaging.

Often, we export them in wooden cases. We mark our products with Grades, Lot Numbers, Size, Degree, and our Trademark. We also make custom markings on the products as per the requirements of our clients.

Quality Assurance

At Mangalam Metal Corporation, all products are subject to strict supervision at each production chain, right from purchasing the raw materials to dispatching products. All the processes undergo inspections for conformity to ASTM, ASME, MSS, and JIS codes and standards.
