Fastener Torque Specs Torque is applied to the fastener in an effort to elastically deform the bolt shank. IMPERIAL Grade 8 bolts, allow a torque variance of ± 5% either way Standard Torques for Metric Bolts Metric Bolts - Table of Standard Torques (± 5% Nm) Grade 8.8 10.9 12.9.Grade 8.8 10.9 12.9 The torque rate can vary considerably for the same diameter of screw. Our bolt torque graphics are undoubtedly essential graphics for operators to keep on hand.

Bolt torque, the amount of force required to tighten a bolt, is listed according either to the Society for Automotive Engineers (SAE), which uses U.S. measurements, or to metric units. Replace, wash and oil cylinder head bolts. You can also publish the lyrics of your favorite song or you can sing it in your own voice and publish it. In the case of bolts and nuts, this elastic deformation between the bolt head and the nut is critical in order to create tension or clamping force to hold the joint together. Manufacturers of bolts and/or machines establish torque specifications for their components and the nuts and bolts that hold them together. Torque values are based on clean, dry threads. to DIN 13, sheet 13 and nuts with height of 0,8 x d acc. Unless otherwise specified use torque values listed above. ; Bolt size Low Grade Grade 8.8 Grade 10.9 Grade 12.9; 6mm: 3-5 5.8 8.8 10.9 Class 5.8 Class 8.8 Class Bolt Head Identification Bolt Size Grade 2 Grade 5 Grade 8 (Metric) Bolt Head Identification Bolt Size (Inches) For me, it all started with writing my diary for a student.
