A hex cap screw, also known simply as a hex bolt, is a type of threaded fastener designed to be used with a threaded nut or tapped hole.

The "hex" in the name refers to the head of the screw, which has a six-sided (hexagonal) shape. This shape is designed to be turned with a wrench or a socket, providing a means to tighten or loosen the screw. The "cap" in the name generally indicates that the head of the screw is larger and flatter, offering a larger surface area to distribute the load or pressure applied during tightening. .

Hex cap screws come in a variety of sizes, materials and thread pitches to suit different applications. They are commonly used in machinery, construction, automotive and other industries where strong and secure fastening is required.

A hex bolt, also known as a hexagonal bolt or a hex head bolt, is a type of threaded fastener commonly used to join two or more components together. It consists of a cylindrical shaft with external threads and a six-sided head, which is designed to be turned using a wrench or socket to tighten or loosen the bolt. The threaded portion of the bolt allows it to be securely fastened into a corresponding threaded hole or nut.

Hex bolts are widely used in various applications, including construction, manufacturing, automotive, machinery and more. They come in various sizes, materials and grades, each tailored to specific requirements based on factors such as load-bearing capacity, corrosion resistance and environmental conditions.

A heavy hex bolt is a type of bolt that features a larger and thicker hexagonal head compared to a standard hex bolt. Like the standard hex bolt, it has a threaded shaft and is primarily used for fastening purposes. However, the heavy hex bolt is designed to provide increased bearing surface and enhanced strength, making it suitable for applications where higher loads or greater structural integrity are required.

Heavy hex bolts are commonly used in construction, infrastructure projects, industrial machinery and applications where structural stability is crucial. Their design helps distribute the applied load more effectively, reducing the risk of deformation or failure under heavy loads.

A carriage bolt, also known as a coach bolt or round head square neck bolt, is a type of bolt designed with a distinctive domed or rounded head and a square section under the head. The square section prevents the bolt from turning when tightened, making it particularly suitable for applications where the bolted joint needs to remain secure while the nut is being tightened.

Carriage bolts are commonly used for wood-to-wood connections, such as attaching wooden components to one another or securing items to wooden structures. The square neck of the bolt fits into a square hole in the wood, preventing the bolt from spinning as the nut is tightened on the other side.

A structural bolt is a specialized type of bolt designed and manufactured to meet specific requirements for use in structural applications where safety and load-bearing capacity are critical. These bolts are used to join structural components together, such as steel beams, columns, trusses and other elements in buildings, bridges, industrial structures and more. They play a vital role in maintaining the structural integrity and stability of these constructions.

Structural bolts typically adhere to stringent industry standards, such as those set by organizations like ASTM (American Society for Testing and Materials) or AISC (American Institute of Steel Construction). These standards define the bolt's dimensions, material composition, mechanical properties and testing procedures to ensure they can withstand the stresses and loads that occur in structural settings.

Tension control bolts are commonly used in industries like construction and bridge building, where consistent and accurate tensioning is essential to ensure the safety and stability of the structure.

A tap bolt, also known as a fully-threaded hex bolt or a tap screw, is a type of bolt that features threads along its entire length. Unlike standard bolts, which have a portion of their shaft unthreaded, tap bolts are threaded from the head to the tip, allowing them to be inserted into a threaded hole or nut for secure fastening.

Tap bolts are commonly used in applications where a fully-threaded connection is required, providing consistent and reliable threading along the entire length of the bolt. They can be tightened using a wrench or socket on the hexagonal head. Tap bolts are often used in situations where a threaded hole is present, and the bolt is used to clamp or hold components together, providing a tight and secure connection.

A lag screw, also known as a lag bolt, is a type of heavy-duty screw designed for secure fastening of heavy objects to wood or other materials. It is characterized by its large size, coarse threads and pointed tip.

A flange bolt is a type of bolt that features an enlarged, flat, and circular flange head. The flange serves a dual purpose: it acts as a built-in washer, distributing the load over a wider area, and it provides a larger surface for applying torque during installation or removal.

A plow bolt, also known as a plough bolt, is a specialized type of bolt designed for fastening applications in which a flush surface is desired. Plow bolts are commonly used in plowing equipment, agricultural machinery and construction equipment, where a smooth and streamlined exterior is important to prevent obstruction or damage as the machinery moves through the ground.

Step bolts feature a wider, lower-profile, round head and are similar to carriage bolts in bearing surface and square-neck design. Step bolts are commonly used in decking applications, or where wood is bolted down because the larger diameter head of the step bolt will not pull through the soft wood. Step bolts' smooth, low, rounded head design also permits movement over the surface.

Timber bolts are commonly used in woodworking projects such as building structures, decks, fences and furniture. Their design is optimized for securely fastening wood components together, and they are particularly useful when a strong and reliable connection is needed while maintaining the aesthetic appearance of the wood surface.

A square bolt is a type of bolt that has a square-shaped head instead of the more common hexagonal head. The square head allows for a wrench or a specialized square socket to be used to tighten or loosen the bolt.

Square bolts are often used in applications where it's necessary to prevent rotation during installation or removal. The square head design makes it less likely for the bolt to slip while being turned, providing better control over the torque applied.

A slotted flat cap screw, also known as a slotted flat head screw, is a type of threaded fastener with a flat head and a single slot (or "slotted") groove on top of the head. This groove is designed to accommodate a flat-blade screwdriver or a similar tool for turning and tightening the screw. The flat head is intended to sit flush with the surface of the material it's being fastened to, creating a smooth finish.

An eye bolt is a type of bolt that has a looped or circular "eye" at one end, which is designed to be used as an attachment point. The eye allows for a variety of connections, such as attaching ropes, cables, chains or other hardware for lifting, securing, or hanging objects.

Eye bolts are commonly used in various applications, including rigging, construction, marine and industrial settings.
