What is Unbrako bolt?

Unbrako High-tensile Fasteners Established in 1911, Unbrako is the ultimate authority in high tensile industrial fasteners and remains the socket screw by which all others are measured .

What are tee bolts?

T-bolt, forged from solid metal. A nut for T-slots becomes a T-bolt, by screwing in a setscrew and gluing, locking or welding it. A slot nut with hole without thread becomes a T-bolt when a standard hexagon bolt is pushed through it. The geometric shape of the slot nut prevents the bolt from turning during assembly.

What do letters on bolt heads mean?

The higher the grade, the stronger the bolt. English bolts have radial lines on their head to identify the grade, or strength class. The number of lines on the bolt head is 2 less than the actual grade. So, for example, a grade 5 bolt will only have 3 radial lines on its head.

What does 10.9 on a bolt mean?

For the 10.9 bolt, the 9 tells the user that the yield strength of the bolt is approximately 90% of the first number: 1,000 MPa. Thus, the 10.9 bolt has an approximate yield strength of 900 MPa (940 MPa by specification). Two other common symbols that are included on metric parts are the “S” and the 3 designations.

Where do we use t headed bolt?

T-Head Bolts, otherwise known as Hammer-Head Bolts, are used in a range of applications – such as the fastening of lift guide rails. They are able to be placed flexibly in required positions within anchor channels.

What are T bolts used for?

T-slot bolts are fixing elements that combine a solid metal t-bolt with a square based t-nut used for fixturing in machines and structures, for example they are widely used in CNC machines. Wixroyd T-bolts are made from forged steel with rolled thread, with strength classes of 8,8 , 10,9 and 12,9.

How can you tell if a bolt is high tensile?

They both use numbers to grade their bolts – the higher the number, the higher the tensile strength. For instance, the SAE system covers diameters of up to 1 ½ inch, and a grade 8 would have a higher tensile strength than a grade 5. Let’s take a look at the markings you would find on some of the most common SAE bolts.

Is a 10.9 bolt hardened?
