fish out of water-"spike threads"?
hi all,
as the subject states, i am a fish out of water with the structural stuff.
i've got a steel plan from my se that calls out anchor rod threads to be 'spiked' at both ends, and was wondering if someone could help explain what that actually means. i would assume it means to destroy the threads in such a way as to prevent the rod from backing out of the nuts, but didn't know if there was a certain method that is commonly used?
the application is for cradling & supporting a bearing beam that is to be cut for the installation of a new reactor. the 'cradle' is made of mc9, hung from w14 across the beam to be cut with 3/4" rod.
thanks in advance for your help,
stacy
