At Monster Bolts, we have all kinds of fasteners for your most challenging home and business projects.
With competitive price and timely delivery, Hebei Bentley Technology sincerely hope to be your supplier and partner.
In addition to all kinds of innovative wood screws, sheet metal screws, and other fasteners, we have a variety of high-design hex bolts including fully threaded and partially threaded options.
Might you want to use these for your next project? It depends. Does the Pope wear a funny hat?
One of the primary reasons that hex bolts are so popular for heavy-duty interior or exterior use is their design.
For context, think about trying to hold things together using your traditional Phillips head wood screws with their relatively small attack surface and your trusty screwdriver.
Now imagine you're up on a ladder somewhere and it's 90 degrees, and you're sweating into your face. Suppose there are bees roaming around you with their stingers out, and you're trying to grab the stuff as quickly as possible and wrestle it into place. Importantly, too, suppose you are trying to hold the angle while you fasten.
In all of these cases, what you want is a surface that takes tool attack from various angles, and where it's relatively easy to get this fastener threaded into place...
Now do you see why hex bolts are so popular? Instead of wrestling with a tiny x, and often stripping the screw head in your frustration, you can grab onto the hex bolt and turn it confidently, just like you would turn lug nuts with a tire iron.
Hex bolts are also, in many ways, the workhorses of the fastener world. They do the tough jobs, and those are the jobs that they are built to do.
Look, these things are not likely to break or bend over time. The diameter of most hex bolts provides quite a bit of security, and with the right alloys and craftsmanship, these fasteners aren't going anywhere. That's why you see them installed on bridges and in various municipal projects where durability is a major concern, and the need for prevailing wage means planners are likely to spare no expense in materials.
That's our “this old house” moment for today. Take a look and get what you need for your next project. Ask us any questions that you have about how to hold stuff together (we don’t do counseling, but we DO do project advice!) – and bookmark us for an easy way to get the gear you need for the long haul.
Hex bolts are measured by their length, diameter, and thread pitch. The length is measured from under the head to the end of the bolt, while the diameter is the width of the bolt's shank. Thread pitch refers to the distance between threads and is typically specified in threads per inch (TPI) or millimeters for metric bolts. Accurate measurements are crucial for ensuring the correct fit in applications.
Hex bolts are versatile fasteners used in a variety of applications, including construction, machinery, automotive, and furniture assembly. Their hexagonal heads allow for easy wrenching and torque application, making them ideal for securing heavy-duty materials. They are commonly used in steel, wood, and concrete structures.
Hex bolts are made through a multi-step process that includes cutting, forging, threading, and heat treating. Initially, a steel rod is cut to the desired length, then forged to form the hexagonal head. Threads are created by rolling or cutting, followed by heat treatment to enhance strength and durability. Finally, the bolts are coated or plated for corrosion resistance.
Hex flange bolts are similar to standard hex bolts but feature a built-in flange under the head. This flange acts as a washer, distributing the load more evenly and providing a larger bearing surface. Hex flange bolts are used in automotive, construction, and industrial applications where extra support and load distribution are needed.
To loosen hex bolts, use a wrench or socket that fits snugly over the hexagonal head. Apply counterclockwise force to turn the bolt. If the bolt is rusted or stuck, apply penetrating oil and let it sit for a few minutes before trying again. Using a breaker bar or an impact wrench can provide additional leverage and make the job easier.
To remove hex bolts, first, ensure you have the right size wrench or socket. Turn the wrench counterclockwise to unscrew the bolt. If the bolt is difficult to remove, apply penetrating oil to loosen rust or debris. In cases where the bolt is damaged or stripped, use bolt extractors or cutting tools to remove it safely.

Hex bolts are commonly made from steel, stainless steel, brass, and other alloys. Steel hex bolts are often zinc-plated or hot-dip galvanized for corrosion resistance, while stainless steel bolts are naturally resistant to rust and corrosion, making them suitable for outdoor and marine environments.
Hex bolts offer several advantages, including ease of installation with standard tools, high strength and durability, and versatility in various applications. Their hexagonal head design allows for greater torque application, ensuring a secure and reliable connection.
Choosing the right hex bolt involves considering the material, size, thread type, and coating based on the specific application. It's important to match the bolt's strength and corrosion resistance to the environment and load requirements of your project.
The main difference between hex bolts and hex screws is that hex bolts are used with a nut, while hex screws are used without a nut and are driven directly into tapped holes. Hex bolts typically have a larger and thicker shank compared to hex screws.
Hex bolts are a type of threaded bolt, characterised by their six-sided hexagonal-shaped head. Hex bolts can be either fully threaded or partially threaded (featuring a clear shank along part of the body) and are suitable for use in a wide range of applications, typically machinery and construction.
They are available in a choice of types, sizes, materials and finishes, providing the freedom and flexibility to select the bolt best suited to your particular task or application. Hex bolts are sometimes also known as hex head bolts or hexagon bolts, again due to their distinctive head shape.
Hex head bolts are versatile and adaptable fasteners, making them suitable for a variety of uses across a range of industries and applications. Example hex bolt uses include hex head screws for wood, metal, and many other environments and scenarios.
They offer strong tensile properties and most standard types can be used in multiple locations (dependent upon the material and finish). As a result, hex bolts are a widely used staple fastener.
Their primary use is for heavy-duty fixing and fastening applications. This could include:
Various different types of hex bolts are available, each best suited to different applications and environments. Hex bolts can be categorised in a number of different ways – chiefly their sizing, the material or finish used in their manufacture, and whether they are fully or partially threaded.
The following sections provide further detail on some of the key hex bolt types, giving you the knowledge you need in order to make a fully-informed buying decision.
Choosing the right-sized hex bolt for your task is important, and there are several factors to take into consideration when measuring hex bolt dimensions and sizes. These are as follows:
The ISO metric thread size system is widely used around the world. It is a handy international standard for measuring thread sizes across an array of different screw and bolt types. Each size is denoted by the letter ‘M’ followed by a number. This number indicates the outer diameter of the thread, measured in millimetres. As an example, a hex bolt with a thread size of M8 would have an outer diameter of 8mm.

Most hex bolt size charts refer to a specific range of products. As a result, it can be difficult to locate an accurate chart which covers a range of hex bolt types and sizes. The following hex bolt size charts should help you to easily select the most suitable product for your requirements.
This size chart focuses on DIN standard 931 bolts (hex bolts which have a partially-threaded clear shank along the length of the body).
