Torque values listed are for general use only. Check tightness of fasteners periodically. Relative Strength Marking 4. Caution: All material included in this chart is advisory only, and its use by anyone is voluntary. In developing this information, Fastenal has made a determined .
Standard tightening torque for metric screw threads. Or for metric sizes: M = P x D. P = bolt tension Newtons. These formulae may be used for bolts outside the range of the . The tightening torque values given in the above table serve only as a guide.
This bulletin covers the following Champion . Suggested Starting Values.
The torque figures quoted have been based on a theoretical bolt load equal to of the proof load of. The following torque values are to be used on all fasteners unless otherwise. STAInlESS STEEl CAP SCREWS. The maximum recommended tightening torque values stated above are for bigHead products under stand-alone test conditions. Maximum permissible torque . Recommended Assembly Torques.
Bolt torque values are calculated by using . Nm, based on a friction coefficient of 0. Bolts that are fully or partially threade with washers and nuts are called as metric bolts. They are of two types, metric flange bolts and metric hex bolts. SAE Plain and Zinc Plated Hex and Socket Head Cap Screws. TORQUE CHART – SAE PLAIN . When working with fasteners of different frictional characteristics, the Nut, or K, Factor . I understand that some of you like to tighten up your bikes bolts by feel rather than using torque wrenches but for those who do use torque. Metric Steel Bolt Torques.
Lubrication effect on bolt tension and torque.
Reduction of torques for lubricated vs. Choosing a bolt that has torque tolerance is important to many industries. SAE J4governs imperial sizes, while ISO 8governs metric -size bolts.
