Grade 8.8 bolt tightening torque

WebThe following suggested tightening torques provide an excellent starting point for determining torque requirements. Remember, you may need to vary these numbers somewhat based on the individual joint or the amount of fastener lubrication. This table is offered as the suggested maximum torque values for threaded products and is only a … WebRather than for each joint individually. If I specify M12 grade 8.8 it should be torqued to 95Nm and a 12.9 should be torqued to 160Nm. If I put an 8.8 where a 12.9 is specified, and try to torque to 160Nm, it will probably damage the bolt. 12.9 where an 8.8 was specified and torque to 160Nm will probably damage the part.
