 Bolt Preload Calculation, Garrett D. Euler,
Apr. 2002. Theory and equations for computing bolt
installation prestress.
 Criteria for Preloaded Bolts (new pdf), NASA
JSC NSTS08307A, July 1998. 93 KB PDF file (ftp). Requires
approximately 19 seconds to download. Contains equations
for bolt stress analysis, including installation prestress and margin of safety
calculation.
 Fastener
Design Manual, NASA GRC RP1228, Richard T. Barrett,
1990. Warning: This 100page
book is a 9.6 MB PDF file (ftp). Extremely large! Requires
approximately 40 minutes to download! Excellent
entrylevel introduction to fasteners, fastener analysis, bolt pattern
analysis, and equations, but does not really explain how to include fastener
prestress.
 Torque
Limits for Threaded Fasteners, NASA MSFCSTD486B,
Nov. 1992. 1.8 MB PDF file (ftp). Requires approximately
7.5 minutes to download! Contains isolated details
regarding bolt prestress but does not contain equations, and is generally
a poorquality document.

Space Flight Structural Fasteners, NASA MSFCHDBK2071,
Oct. 1992. 0.58 MB PDF file (ftp). Requires approximately 3
minutes to download. This is a list of some of
the fasteners preferred in aerospace structural applications but is
certainly not exhaustive. Generally, any 1100 MPa (160 ksi), A286
bolts having an NAS or NA part number are highstrength,
aerospacequality fasteners.
