Grade 12.9 Bolt

High Tensile 12.9 Allen Bolt & 12.9 hex bolt suppliers in UAE

What is Grade 12.9 Bolt?

Bolts made of grade 12.9 are high in strength. It has a min yield strength of 1100 MPa and a min tensile strength of 1220 MPa. The Grade 12.9 Bolt is used for some of the heaviest jobs like securing an engine. The 12.9 grade bolts suppliers supply these products to be used in high stress environments. In fact, High Tensile Bolts 12.9 Grade is the highest class for metric bolts. This can be understood by their tensile strengths, which 120 percent more for 12.9 High Tensile Bolts than grade 10.9 bolts.

The Grade 12.9 Bolts are threaded fasteners that come with external male threads which need to match the pre-formed female thread, like nuts. The Class 12.9 Bolts are known for their long life cycle and are easy to install and uninstall. The 12.9 Bolt is made of carbon steel and can be customised to different shapes and sizes. The 12.9 hex bolt comes with a hexagonal-shaped head.

The m10 12.9 bolt is quite adaptable and offers strong fixing. The M12 12.9 bolt comes with a 12mm thread diameter. The m8 12.9 bolt is used in many applications like securing heavy metals, timbers, etc. The Allen Bolt 12.9 Grade can be efficiently used in small, awkward spaces.

It is to be noted that the hardened 12.9 Bolt Grade becomes fragile due to thinning out. The 12.9 Bolts can perform very well, even in unfavourable environments like acidic or alkaline mediums.

Difference between UNC, UNF, 8UN Metric 12.9 bolt

UNC or Unified Coarse Thread is a kind of Unified Screw Thread (UST) standard. The UNC class 12.9 metric bolts come with unbroken series of coarse threads of right-turns, and they have uniform geometry. The UNF or Unified Fine is also a kind of UST, and these fixings are often used in the aerospace and automotive industries. The 8UN metric 12.9 bolt has 8 threads per inch irrespective of the diameter, and they are generally used on 1” or larger diameters.

12.9 Allen Bolt vs 12.9 hex bolt

Both hex and Allen bolts have a hexagonal head, but they have a few differences. The 12.9 Hex Head Bolts are used in applications where strength is critical, and it can be easily installed and uninstalled. The 12.9 Allen Bolt comes with a recessed top where the key can be inserted.

What’s the difference between standard bolts and 12.9 Metric Bolts

For the standard bolts, the size of the head is measured in terms of inches or a fraction of an inch. However, for 12.9 Metric Bolts, the head size is measured in millimetres.

How to identify metric 12.9 bolt?

The metric 12.9 Grade Bolt is denoted by the letter M followed by a number which is the nominal diameter of the bolt shaft described in millimetres.
