If you exceed the proofload value when tensioning the bolt, you run the risk of bolt failure. Bolt Torque Charts These charts show suggested maximum torque values for threaded products and are intended only as a guide. The numerical code shown on the head of a DIN bolt specifies the strength type. Use of its content by anyone is the sole responsibility of that person and they assume all risk. | Feedback The below chart refers to usage in steel. Clamp loads for Grade C lock nuts equal 75% of the bolt proof loads specified for SAE J-429 Grade 8, and ASTM A-354 Grade BD bolts. Engineering ToolBox - SketchUp Extension - Online 3D modeling! Torque - FT LBS. Torque Chart. Lubricated refers to fasteners in the “As Received” condition, which is normally a light preservative oil coating on unplated fasteners and no oil coating on plated fasteners.
