What is the specification for torque?
By definition, torque refers to the amount of rotational force at the point of application. When attaching a wheel to a vehicle, torque specifications are the amount of force recommended on the hardware to ensure proper installation.
How do you tell the grade of a bolt?
You can usually figure out the grade, or strength, of a bolt by looking at the markings on its head. English bolts (U.S.S. or S.A.E) are categorized by grade, from grade 2 to grade 8, where the grade represents inch strength. The higher the grade, the stronger the bolt.
What is torque value NM?
Torque is measured in Newton metres (Nm) or you might see the imperial measurement of lb-ft (pounds-feet). If you want to calculate the conversion for yourself, 1 Nm is equivalent to 0.738 lb/ft. See the pulling power of torque in our tug of war video.
What is a grade 12.9 bolt?
Grade 12.9 Hex Bolts are high strength bolts with 1100MPa minimum yield strength and 1220MPa minimum tensile strength. Suraj Metal Corporation is a leading manufacturer and supplier of the different types such as the Grade 12.9 Hex Head Bolts and others.
What does 12.9 mean on a bolt?
In metric classes, bolts that have been graded as 12.9 have the highest strength. In comparison to grade 8.8, the strength of Grade 12.9 Bolts is very high, where their minimum ultimate tensile strength is valued as high as 1242 Mpa. These fasteners are renowned for having a high tensile strength.
How strong is a grade 12.9 bolt?
Grade 12.9 Hex Bolts are high strength bolts with 1100MPa minimum yield strength and 1220MPa minimum tensile strength.
