Bolt Torque Chart Template. Due to many variables that affect the torque-tension relationship like human error, surface texture, and lubrication the only way to determine the correct torque is through experimentation under actual joint and assembly conditions. 3/8" - 24 Q .332 50 35 .

"+ (dt.getFullYear()) +" "+ (("0"+dt.getHours()).slice(-2)) +":"+ (("0"+dt.getMinutes()).slice(-2)); Unlike the DIN 931 and DIN 912 the shank of a DIN 933 bolt goes up to the head. Proper torque spec varies depending on the material, bolt grade or wether lubrication is used such as oil, wax, or anti-seize Always go to the manufacturer for proper torque specs … This is done to allow a safety buffer so that the bolt does not get too close to the proofload value.
