Zusammenfassung:The Industrial Fasteners Institute (IFI) in Cleveland initiated a study in 1993 to perform actual fastener testing. IFI created a task group consisting of association staff personnel, technical representatives from association member companies, and other interested fastener and thread experts. Their task was to manufacture, measure and test fasteners to develop data that would relate thread size to fastener performance. Both aerospace and commercial assemblies were to be tested. The effect of nut-thread size on aerospace joint performance was investigated by making nuts with common characteristics and controlled lots with different thread dimensions. The mating bolts for the test were a single lot of standard MS 21250 tension bolts. For the commercial hex fasteners, cap screws, and nuts with common characteristics except for thread dimensions were manfuactured in accordance with B18.2.1 and B18. 2.2 in controlled lots and investigated for conformance to standard performance requirements. The tests and their results are examined in detail.
