TM 5-3895-373-20 APPENDIX F TORQUE LIMITS SECTION I. INTRODUCTION F.1. SCOPE. This appendix provides general torque limits for hex head cap screws, bolts, and set screws for the 780T bituminous asphalt paving machine. F.2. EXPLANATION OF TABLES FOR CAP SCREWS. BOLTS, AND SET SCREWS. a. Torque values are based on plain, unplaced hardware that has been degreased and dried. The values are also based on clamping steel to steel. All torque values, including special cases, are identified in the applicable task. If a task torque value differs from a corresponding table value, the task value must be used. b. Section II. Torque Limits for Hex Head Cap Screws and Bolts. This table lists torque values for SAE Grade 8 fasteners. Grade 8 fasteners can be identified by 6 radial dashes on the head, each set 60° apart. c. Section III. Torque Limits for Set Screws. This section consists of two tables that list torque values for U.S. standard and metric set screws. Torque values will be for SAE Grade 5 or ISO Class 8.8 unless otherwise stated. F.3. HOW TO USE TORQUE TABLES FOR CAP SCREWS, BOLTS, AND SET SCREWS. a. Measure the shaft diameter of the cap screw or bolt to be installed. b. Determine the number of threads per inch. c. Locate the fastener in the left-hand column by both diameter and threads per inch. d. Look across the row to obtain the torque limit in Ib-ft or N•m. F-1
