I am looking for a reference which is VDI 2230 Systematic Calculation of High Duty Bolted Joints, 1986 edition. Page 33. If someone has it, please help. Thanks. I cannot find it on the web. Or, I would like to have some source to show Bolts Shear Strength is 0.62 of the Tensile Strength. Please help to let me know where can I find it.

Fastener Standards Sixth Edition copyright 1988 by the Industrial Fastener Institute page M-58
" Ultimate shear strength of carbon steel approximates 60 percent of its ultimate tensile strength. And of course, a suitable factor of safety should be applied."
Does this assist you?

8533: In addition to Paskenell's citation, here are a few more sources, also. (1) Barrett, Fastener Design Manual, NASA RP-1228, 1990, , p. 21, "In the absence of specific bolt shear strength values, the following approximations for bolt ultimate shear strength Ssu may be used [for one or two bolts in line of force]. For alloy and carbon steel bolts, Ssu = 0.60 Stu, and for stainless steel bolts, Ssu = 0.55 Stu," where Stu = bolt ultimate tensile strength.
(2) Kulak, et al., Guide to Design Criteria for Bolted and Riveted Joints, 2 ed., Wiley, 1987, pp. 44-50, "For high-strength alloy steel bolts [ISO grades 8.8, 10.9, SAE grades 5, 8], Ssu = 0.62 Stu for one or two bolts in line of force."
(3) Fisher, "Structural Steel and Steel Connections," 2002, (1.45 MB), p. B-5, Eq. B-3, "Ultimate shear strength of a single [high-strength alloy steel] bolt is Ssu = 0.62 Stu."
