Question 1

What are Hex Bolts and where are they commonly used?

Accepted Answer

Hex Bolts are six sided head fasteners used to securely join two or more components in structural, mechanical and industrial applications. Their design allows for easy installation with standard tools, even in restricted spaces. These bolts are widely used in steel fabrication, heavy equipment assembly, infrastructure development, automotive assemblies, marine structures and oil & gas facilities due to their high strength and durability.

Question 2

What is the difference between fully threaded and partially threaded Hex Bolts?

Accepted Answer

Fully threaded Hex Bolts have threads running along the entire shank length, providing a greater grip in applications requiring maximum thread engagement—like fastening two threaded components or using a nut over the full length. Partially threaded Hex Bolts have an unthreaded portion near the head (known as the grip length), which offers shear strength and is ideal for structural connections where alignment and clamping force are critical. Choosing between the two depends on the mechanical design and load distribution of your assembly.

Question 3

Can Hex Bolts be used in high temperature or cryogenic environments?

Accepted Answer

Yes, but the material selection is critical. For high temperature applications, Alloy Steel or Stainless Steel 316/310 are preferred for their heat resistance. In cryogenic conditions, Duplex Steel and certain stainless grades retain toughness and prevent embrittlement. It’s essential to match the bolt material to the temperature range and application to avoid failure due to thermal expansion or material degradation.
