Calibration of Alloy Steel Bolts
Performance of alloy steel structural bolts when subjected to various conditions of installation and load was determined; bolts investigated were ASTM A354 Grades BC and BD and ASTM A490; variables included bolt diameter, grip length, thread length under nut, and thread lubrication; problems investigated included behavior of bolts loaded in tension by either direct axial force or by torque, response of bolts installed by torquing to subsequent application of direct tension, effect of reinstallation, differences between tests performed in hydraulic load cell and field behavior of bolts, incremental vs continuous torquing, and effect of thread lubrication; conclusions and recommendations are made concerning alloy steel bolts used as structural fasteners.
