Excessive tightening torque<\/strong> can stretch the thread, deform components (like a cylinder head) or snap the screw clean off.<\/li>\n<\/ul>\n\n\n\nIn the absence of torque specifications provided by the manufacturer, it is sometimes necessary to apply the standard torque values according to the type and diameter of the bolt. The following table lists the most common reference values for ISO metric bolts, standard thread, in classes 8.8 and 10.9.<\/p>\n\n\n\n
Noticed<\/em> :<\/strong> The values are indicative. For critical assemblies (safety, engines, structures), use the manufacturer's data or the applicable ISO\/UNI standard. Lubrication, nut type, engagement depth, and surface roughness strongly influence the required torque.<\/p>\n\n\n\n\n
