Tensile strength and pull out force of a bolt

[Ben Laycock]

Hi,

I'm looking for some help regarding working out the tensile strength of a M8, grade 8.8 bolt and the pull out force.

What information do I need to gather regarding the bolt and the material the bolt is engaging in to?

Thanks,

Most of the formulas are on pgs 1278-1279 of MACHINERY'S HANDBOOK 23 REVISED EDITION, INDUSTRIAL PRESS INC. New York, ISBN 0-8311-1200-X.
This is an older edition so the page numbers may have changed, the chapter is "Fasteners" and the section is "Working Strength of Bolts."

The chapter following is "Threads and Threading," which may also be useful.
