Focus on M8 Titanium Bolts


In the realm of fasteners, M8 titanium bolts stand out for their exceptional strength, durability, and versatility. These bolts come in various types, each tailored to specific applications across different industries. Let's delve into the world of M8 titanium bolts, exploring their types and common uses.



Let’s start by looking at the system of bolt specification because it provides detailed information about the dimensions of a bolt.

We will use an "M8x1.25x45" bolt as an example:

M8: Diameter

   - The "M" indicates that it is a metric bolt.

   - The number "8" represents the nominal diameter of the bolt in mm. In this case, the bolt has a diameter of 8 mm.

1.25: Pitch

   - The number after "x" denotes the pitch of the bolt's threads, which is the distance between the threads measured in millimetres (mm). In this example, the pitch is 1.25 mm, indicating that the threads are spaced 1.25 mm apart.

45: Length

   - The last number represents the length of the bolt, measured from the tip to the bottom of the head. In this case, the bolt is 45 mm long.

In summary:

- M8: Metric bolt with a diameter of 8mm.

- 1.25: Thread pitch of 1.25mm (distance between threads).

- 45: Length of the bolt is 45mm.


This specification system facilitates a standardised method of conveying the crucial dimensions and characteristics of bolts. This simplifies the process for engineers, technicians, manufacturers, and enthusiasts to choose the appropriate bolt for their specific application.

Please be aware that countersunk bolts deviate from the norm mentioned above because the length measurement includes the head. This means that, for instance, an M8x1.25x45 countersunk bolt measures 45mm from end to end.
