Wondering what a Hex Bolt is and what applications it can be used for? Here is a brief description of the Hex Bolt and its various specifications. Find out more about the different lengths and sizes available, and how you can use this bolt in your next project.

1. What is a Hex Bolt?
A Hexagon Bolt, commonly known as Hex Bolts, are threaded
fasteners with a hexagonal head shape. This type of bolt is made to
be installed using a spanner. Hexagon Bolts are preferred for their
robust shape, which makes them suitable for more heavy duty
fastening applications. Hexagon bolts are also usually available in
larger sizes than alternative fasteners.
Hex bolts are six sided heads that are the industry standard for
fasteners with forged heads. American Society for Testing and
Materials (ASTM) A307 grade A bolts, all SAE hex bolts, and
various other common specifications require a standard (finished)

2. hex head. For specifications such like as A307 grade B, A325 and
A490 that require a heavy hex pattern, points to dimensional
tolerances for heavy hex bolts or structural bolts.
Hex Bolts are known as
• Hex head bolts
• Cap screws
• Hex cap screws
• Hex head cap screws
• Machine bolts
• Hex machine bolts
• Hex head machine bolts
• Tap bolts
• Hex tap bolts
• Hex head tap bolts

3. Length and Sizes of Hex Bolts
The size and length of inch series fasteners — is indicated in
inches, generally fractional rather than decimal. Size points to the
nominal diameter of the bolt while length is just that—how long the
bolt is.
Hex bolts length in size from 1/4" to 4" in diameter; 1/4" to 1 1/2"
sizes are widely available.
Lengths range from 3/8" to 24"; 1/2" to 10" is typical. From 3/8" to
1", lengths are in 1/8" increments. Between 1" and 4", 1/4" steps
are normal. From 4" to 8", lengths generally increase by 1/2".
Longer than 8", expect 2" steps. Length is evaluated from the under
head bearing surface to the extreme point that is threaded at end of
the bolt.
Larger lengths are not constructed in short ranges, similarly smaller
lengths are not available in long ranges. Not all hex bolts are easily
available in all sizes and lengths.
The bolt must be long enough to allow at least two full threads to
extend beyond the nut face after tightening, which ensures full
thread engagement with the nut. However, there should be two full
threads exposed on the head side of the nut to make sure the nut
can be properly tightened. More exposed threads within the grip the
area between the head and the nut will result in a "springier" bolt. It
is also recommended that threads should not be in the shear
planes.

4. Applications of Hex Bolts
Hex bolts might be used for many different applications that include
fastening wood, steel, and other construction materials for projects
such as docks, bridges, highway structures, and buildings. Hex
bolts with forged heads are also widely used as headed anchor
bolts.
