- Bolt Preload Calculation, Garrett D. Euler,
Apr. 2002. Theory and equations for computing bolt
installation prestress.
- Criteria for Preloaded Bolts (new pdf), NASA
JSC NSTS-08307A, 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 RP-1228, Richard T. Barrett,
1990. Warning: This 100-page
book is a 9.6 MB PDF file (ftp). Extremely large! Requires
approximately 40 minutes to download! Excellent
entry-level 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 MSFC-STD-486B,
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 poor-quality document.
- <currently unavailable> Preferred
Space Flight Structural Fasteners, NASA MSFC-HDBK-2071,
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), A-286
bolts having an NAS or NA part number are high-strength,
aerospace-quality fasteners.
