How do you find the torque value of a bolt?
DETERMINING TORQUE The general equation for bolt load based on applied torque is T = KFiDb where K = torque coefficient. K is a function of the coefficients of friction and collar friction in the joint, and these are based on variables such as surface finish, coatings, and so on.
How is bolt torque value calculated?
How tight should wheel nuts be NM?
Lock-off. Once you have the correct setting dialed in, tighten the lock screw at the base. NOTE: Torque wrenches tend to be more accurate when they’re set to the middle of their range. This wrench goes from 28Nm to 210Nm – which is ideal for our wheel nuts, at about 90Nm.
What is a torque value?
Torque is a twisting force measuring force multiplied by distance – foot or inch pounds in the US and Newton-Metres in Europe. Usually distance would be the length of the wrench (say 2 feet) and your hand would apply force (2-foot wrench, 10 pounds of pressure equals 20 foot-pounds). [
What is the best grade of torque for bolts?
Grade 2 bolts are cheap but not very strong, grade 8 bolts are the strongest and most expensive, and grade 5 bolts are the most common. Refer to the charts to find the ideal tightening torque.
How to find the ideal tightening torque?
Refer to the charts to find the ideal tightening torque. Bolts are graded using various systems, but in the United States, the main bolt grading system was designed by SAE, the Society of Automotive Engineers. The grading indicates the material strength of the bolt. The higher the grade, the stronger the bolt.
What does grade 8 mean on a bolt?
The grading indicates the material strength of the bolt. The higher the grade, the stronger the bolt. The most common SAE bolt grades are Grade 2, Grade 5, and Grade 8. Very few applications outside of industry require higher than a Grade 8 bolt.
What is a Grade 2 bolt?
Grade 2 bolts are cheap but not very strong, grade 8 bolts are the strongest and most expensive, and grade 5 bolts are the most common. Refer to the charts to find the ideal tightening torque. Bolts are graded using various systems, but in the United States, the main bolt grading system was designed by SAE, the Society of Automotive Engineers.
