ABSTRACT
This article provides information on several types of screws to be used on different types of surfaces and examines several reasons behind the loosening of fasteners. Vibration loosens fasteners by creative relative motion between the threads. Suppliers have designed screws specifically for aluminum and other light alloys. The Delta PT fastener from Semblex reduces radial stress on the boss. Using a tool that will apply the right torque accurately is as important as setting it.
