For SI: 1 inch = 25.4 mm, 1 lbf = 4.4 N, 1 psi = 6.895 kPa.
1
For purposes of measuring overall fastener length, fasteners must be measured from the underside of head to bottom of tip.
2
Length of thread includes tip. See detailed illustration.
3
Bending yield strength determined per methods specified in ASTM F1575 and based on the minor thread diameter.
4
Fastener installation and design values require complete threaded portion to be embedded in the main member.
5
Fastener bending yield strength is determined by the 5 percent diameter (0.05D) offset method of analyzing load-displacement curves
developed from bending tests.
6
Allowable shear strength values apply only to shearing in the unthreaded shank portion of the fastener.
