Hex Bolts

Hex Bolts


Bolts are fasteners, which help in connecting different items together. They play a critical role in the construction of different types of projects across several industries. Consisting of a male thread in their exterior, they are fitted with a matching female nut to tighten them. There are 12 types of bolts each, having their own properties and functions.


A hex bolt is a six-headed structure with threading’s starting from the shank of the component. This style is common throughout the industry for fasteners with a forged head. They are widely used in different industries. The construction and engineering sectors use these components frequently for two different projects or fixing material on a single building.

These modules are used in systems that require a strong and steady fastener. The design of the material means that it has to have excellent tensile properties and strength. They are widely used in fastening docks, bridges, buildings, and highway structures. Their versatility makes them suitable for diverse jobs as the hexagonal head holds a strong grip. They are also easy to loosen or tighten as there is an abundance of space to move the tools in all directions. These components can be easily availed in different finishes, lengths, and styles making, them highly desirable.

What are hex bolts called?

These components are also referred to as hex cap bolts, hexagonal screw head bolts, machine bolts, and hex cap screws. They are very common across the construction and repair industry. Each of these bolts is designed with a unique property, which sets it apart from the rest. They can be readily produced using stainless, carbon, and alloy steel.

Difference between hex screw & hex bolt

The terms of both these components are interchanged several times and used incorrectly. We will help you understand what both these modules are designed to be.


These components consist of external threading with the hex head designed to be driven using a wrench. They can be partially threaded up to a certain length or fully threaded. The components are designed to be inserted in openings with tapped ends. They are machined which can be later available in coarse or fine thread. They are installed by turning a nut to tighten the component.


These modules have an in-build shoulder, which is threaded under the head. This helps in increasing the overall tensile strength of the component. The threaded length of the screw is very limited and cannot be utilized for all applications. They are fitted by turning the head of the bolt and then assembling and tightening it.

Is Torx better than hex?

Torx bolts are made up of a six-headed star-like shape. These components have some key advantages over a fastener. Firstly, their design would prohibit them from stripping away due to the way load is distributed in the system. This allows them to be fastened tightly making, them highly secure. The load handling capacity of the module allows the module to have a smaller size which makes it highly desirable.

Is a hex bolt the same as an Allen?

Both these components are nearly the same. With Allen bolts having 6 heads structure but a hollow opening which enables the wrench to tighten it to a fitting. They are also less likely to cam out or stripped as it has a lot of contact area.

What can I use for a hex bolt?

These modules are commonly produced utilizing steel. They can also be manufactured using aluminum, brass, copper, and plastic. The components can be readily hardened or produced utilizing stainless steel. Various alloys are also used while making these fasteners. This provides consumers a rich choice of options while selecting a bolt suitable for their operation.

What is the difference between a hex bolt and a hex cap screw?

A hex cap screw is designed with tighter tolerances across the body dimensions. They have features, which have a chamfered end and have a washer face under the head of the bolt. They are commonly referred to as finished hex bolts. A hex bolt on the other hand, has a flat end and doesn’t possess a washer face under the head.
