   5. Set screws and similar threaded fasteners not under tensile stresses [5] [6] 6. (Now withdrawn) Nuts with specified proof load values – Fine pitch thread [7] 7. Torsional test and minimum torques for bolts and screws with nominal diameters 1 mm to 10 mm [8]

3. ASTM A325 - Wikipedia

   en.wikipedia.org/wiki/ASTM_A325

   To minimize confusion, bolt head markings are unchanged and the designation A325 is retained as a grade name within the new standard. [4] In 1951, A325 bolts were recognized as equivalent to a hot driven ASTM A141 rivet. [5]

4. ASTM F568M - Wikipedia

   en.wikipedia.org/wiki/ASTM_F568M

   This standard defines property classes, the metric equivalent of a screw grade, that are almost identical to those defined by ISO 898-1, [2] except for the addition of the 8.8.3 and 10.9.3 classes. These two additional standards are fasteners that have the same mechanical properties as their base property class (i.e. 8.8 and 10.9), but are made ...

   For example, a property class 5.8 bolt has a nominal (minimum) ultimate tensile strength of 500 MPa, and a tensile yield strength of 0.8 times ultimate tensile strength or 0.8 (500) = 400 MPa. Ultimate tensile strength is the tensile stress at which the bolt fails.

6. Bolted joint - Wikipedia

   en.wikipedia.org/wiki/Bolted_joint

   The applied torque causes the bolt to "climb" the thread causing a tensioning of the bolt and an equivalent compression in the components being fastened by the bolt. The preload developed in a bolt is due to the applied torque and is a function of the bolt diameter, the geometry of the threads, and the coefficients of friction that exist in the ...

7. Torque-to-yield fastener - Wikipedia

   en.wikipedia.org/wiki/Torque-to-yield_fastener

   The torque applied to the fastener must be determined such that it does not contribute to a service condition where the fastener enters a low-cycle fatigue regime. In general, the use of torque-to-yield fasteners is deprecated except in cases where the materials and structures comprising the entire assembly are certified to be within tolerances ...
