ASTM F 1852 - 05 Standard Specification for Twist Off Type Tension Control Structural Bolt/Nut/Washer Assemblies, Steel, Heat Treated, 120/105 ksi Minimum Tensile Strength

American Society for Testing and Materials (ASTM). Current edition approved Jan. 1, 2005. Published January 2005. Originally approved in 1998. Last previous approved in 2004 as F 1852–04a. 8 p. This specification covers two types of heat treated, steel, tension control bolt-nut-washer assemblies, also referred to as “sets.” These assemblies are capable of developing a minimum predetermined tension when installed by applying torque to the nut, while at the same time applying a counter torque to separate the spline end from the body of the bolt using an appropriate spline drive installation tool.
