SAE bolt grades indicate the strength of the bolt. Each bolt grade has an ideal tightening torque for maximum clamping force without breaking. 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.

Lubricate on bolt threads and nut faces with compatible antiseize*. (Mulitply torques by 0.70 for PTFE coated bolting and use additional compatible lubricant on threads/nut faces). This Chart gives the torque value for the final pass. After hand tightening, torquing must follow a cross bolting sequence as.

2021. 7. 21. · Tightening Torque The tightening torque values given in the above table serve only as a guide. A k factor of 0.2 has been used which assumes threads are plain finish, burr free with a light oil coating. It should be noted that these figures are based on the first tightening of single assemblies in isolation. Note:.
