Bolt proof strength
WebThis measurement is given in pounds per square inch (psi). The proof load specification for a Grade 5 bolt is 85,000 psi for bolts 1/4- to 1-inch long. Bolts over 1 to 1.5 inches long must endure a proof load of 74,000 psi. The ASTM requires the proof load specification for a Grade 5 bolt to be 55,000 psi for bolts from over 1.5 to 3 inches.
