Evaluation of Three Diver-Installed Fastener Systems
Many salvage operations require the attachment of lifting points by drivers. As part of the Navy-Makai dive series in late 1971 both threaded and power velocity attachment systems were evaluated for diver use. One-half-inch-diameter eyebolts installed in diver-drilled and tapped holes in 1-inch steel plate had an average ultimate pullout strength of 21,500 pounds and required 7.8 minutes to install. Diver-installed power velocity studs and 1/2-inch-diameter eyenuts had an average ultimate pullout strength of 20,000 pounds in 1-inch-thick steel plate and required 1.4 minutes to install. Simple padeyes attached with three threaded fasteners were 2.1 times stronger than the single fasteners. (Author Modified Abstract)
