Popular trends in hex bolts and nuts for general applications

Popular trends in hex bolts and nuts for general applications: Hex bolts or hex cap screws are commonly used in the construction and manufacturing trades. We also call them hex cap bolts, machine bolts or hexagon screw head bolts. A wide range of sizes are used in general work. We find it used in various places like petrochemical industry, construction, food machinery industry and solar power installations.

The best way to choose a hex bolt nut for your job will depend on the material you choose. You can find a variety of nuts and bolts from hex bolt manufacturers. The most common types of screw head bolts are:

  • Carbon steel bolts
  • Stainless steel bolts
  • Alloy steel
  • Brass
  • Aluminum
  • Silicon bronze

Stainless steel is commonly used for most applications due to its durability and high strength. This is one of the most common hardware applications used to make 18-8 hex bolts and nuts. Next is the 316 grade which has high corrosion resistance. It is mostly used in salt water. It is more expensive than 18-8 steel. If the nut or bolt has burrs or scratches, it will not affect the life and will not cause corrosion because the corrosion resistant material is present inside. They have a distinctive clean silver color and shiny appearance. These bolts are slightly magnetized due to threading and cold forming. This type of fastener is common for exterior fastening and decorative purposes as it is very attractive.

Highly corrosion resistant steel

Zinc plated is a low carbon steel that is coated with zinc. It is either Grade 2 or Grade A307A. It has moderate resistance to corrosion. Grade 5 is zinc plated medium carbon steel. This grade is between Grade 2 and Grade 8. Most automotive applications use this grade of steel. In Grade 8 we have two types. One is zinc plated grade 8 yellow steel and the other is grade 8 plain finish. You can get more information from hex nut bolt manufacturers before placing your order.

Both of these are tempered medium carbon steels. Grade 8 is stronger than Grade 5 and is used in high strength applications. A plain finish means it is not plated. Chrome plate is another type of steel. It has a mirror like finish. Hot dipped galvanized steel is also used. Both it and chrome are low carbon steels for general use. Both have a high degree of resistance to corrosion.

Structural bolts have a larger diameter than hex bolts. The most common type of structural bolt is A325. There are two types in use. One is a plain finish and the other is hot dipped galvanized steel. The plain finish is unplated and made from SS Fasteners Manufacturers carbon. Hot dipped galvanized is also a medium carbon steel used in structural connections. It has good corrosion resistance.
