The Unifix Grade 10.9 HT Hexagon Bolts are essential heavy-duty fasteners designed for professionals and DIY enthusiasts working in automotive, construction, and industrial machinery assembly. These high-tensile steel bolts offer superior structural integrity and reliability under significant load-bearing conditions, though users should ensure they are using the correct torque specifications for their specific application to avoid potential metal fatigue or stripping.

The 10.9 grade denotes the mechanical properties of the steel, indicating a nominal tensile strength of 1000 MPa and a yield strength of 900 MPa.
These bolts are standard grey high-tensile steel. They are not explicitly galvanized and may require protection if used outdoors.
Yes, provided the load-bearing requirements match the 10.9 grade specifications as dictated by local engineering standards.
You will need a standard metric wrench or a socket set corresponding to the head size of the specific bolt diameter.
The partial thread design increases the bolt's strength in the shear plane, making it superior for applications requiring structural alignment.
Ensure the socket size is an exact match and that the tool is fully seated on the bolt head before applying pressure.
Check the thread pitch and diameter to ensure compatibility; verify that there is no debris or paint in the receiving threads.
For proper installation, always use a calibrated torque wrench to ensure the bolt is tightened to the manufacturer's recommended specification for the specific joint. Avoid over-tightening, as even high-tensile steel can fail if pushed beyond its yield point. These bolts are compatible with standard metric nuts and washers of the same strength grade. To prevent oxidation, store in a dry, cool environment, and consider applying a light layer of industrial grease if the bolts are being installed in environments with high moisture levels.
