What are the effects of slotted holes on bolts?
The study is primarily concerned with the effect oversize and slotted holes have on:(1)losses in bolt tension after instal- lation, (2) the slip resistance of a joint, (3) the ability to tighten bolts using the standard installation technique, (4) whether washers are needed for oversize holes and (5) the changes in bolt tension during testing.
