3、ntrol bolt-nut-washer assemblies,also referred to as“sets.”These assemblies are capable of developing a minimumpredetermined tension when installed by applying torque to thenut,while at the same time applying a counter torque toseparate the spline end from the body of the bolt using anappropriate sp
4、line drive installation tool.1.2 An assembly consists of a tension control bolt withspline end(covered by this specification)and a suitable nut andwasher covered by reference to applicable ASTM specifica-tions.1.3 The fastener assemblies are intended for use in struc-tural connections.These connecti
