How do you calculate torque to yield a bolt?
How do you calculate torque to yield a bolt?
You can identify a torque-to-yield or stretch-style fastener by the narrow shank just below the washer face and before the thread run. A bolt of this design is intended to be installed in the plastic range and cannot be reused after being tightened once.
What is the correct torque for a SAE J429 bolt?
SAE J429 governs imperial sizes, while ISO 898 governs metric-size bolts. 1/4 to 3/4in. >3/4 to 1 1/2in. For imperial bolts, grades 5 and 8 are most common. SAE J429 conforming bolts will have radial markings machined on the head of the bolt that indicate bolt grade.
