In order to avoid any confusion when ordering, we
suggest conforming to the Industrial Fasteners Institute
measures as shown here. Please be sure, when ordering
by overall length, that it is clearly indicated as such.

TOLERANCES ON STUD BOLT LENGTHS

All our stud bolts have been manufactured according to
the requirements of ANSI standard B16.5, as outlined by
the Industrial Fasteners Institute. All studs are measured
from the first full thread to the last full thread.
Flat chamfer points are not included in this measurement.
Actual length tolerances are as follows:

Length in Inches                       Tolerances in Inches
Length up to 12 ………………….. + or – 1/16
Over 12 to 18 …………………….. + or – 1/8
Over 18 …………………………….. + or – 1/8
