A hex bolt, also known as a hexagon head bolt, is a common type of fastener widely used in various mechanical and construction applications. Here is a detailed introduction:
Head: It features a hexagonal head, which provides a flat surface with six sides. This hexagonal shape allows for easy gripping and turning using a wrench or socket, enabling efficient tightening and loosening. The head may also have markings or specifications engraved on it, indicating the bolt's material, strength grade, and other relevant information.
Shank: The shank is the long, cylindrical part of the bolt that extends from the head. It has a threaded surface along its length, which is designed to engage with a corresponding nut or a threaded hole in a workpiece. The diameter and length of the shank can vary depending on the specific application and requirements.
Thread: The thread on the shank of the hex bolt is typically a standard screw thread, such as a metric or imperial thread. The pitch of the thread, which is the distance between adjacent thread ridges, is carefully designed to ensure proper engagement and clamping force.
Hex bolts are commonly made from various metals, including carbon steel, stainless steel, and alloy steel. Carbon steel bolts offer good strength and are relatively inexpensive, making them suitable for many general - purpose applications. Stainless steel bolts, on the other hand, have excellent corrosion resistance, making them ideal for use in harsh environments or where exposure to moisture and chemicals is a concern. Alloy steel bolts are often used in high - stress applications that require greater strength and durability.
Hex bolts are used in a vast number of applications. In the automotive industry, they are used to assemble engine components, chassis parts, and body panels. In construction, they are employed to connect structural members, such as beams and columns, and to fasten machinery and equipment to the floor or other surfaces. They are also widely used in the manufacturing of furniture, appliances, and various mechanical devices.
High Strength: Hex bolts can provide a high clamping force, ensuring a secure and reliable connection between two or more components. This makes them suitable for applications where structural integrity and stability are crucial. Easy Installation and Removal: The hexagonal head design allows for easy access and operation with common tools, facilitating quick installation and removal during assembly, maintenance, or repair processes.
Versatility: They come in a wide range of sizes, materials, and strength grades, making it possible to select the appropriate hex bolt for almost any application, whether it's a small - scale DIY project or a large - scale industrial installation.

Hex bolts are six-sided bolts made of low-carbon steel and frequently used in construction and repair applications. A few of the most common specifications include: ASTM A307A, A354, and F1554. Hex bolts can be partially threaded or fully threaded, which are more commonly referred to as a tap bolt. They are typically manufactured by a hot-forging process and allow for a die seam across the bearing surface. If your application requires a thicker head, consider using a heavy hex bolt or structural bolt for structural steel-to-steel connections. We also carry Grade 8 hex bolts.
Hex bolts are often mistakenly called hex cap screws, though the main difference is that hex cap screws feature a washer face under the head and a chamfered point, and a hex bolt does not have a washer face or chamfered threads. Hex cap screws are used in more precise applications like OEM where a tighter tolerance is required.
