CORROSION Galvanic compatibility (corrosion)
ENGINEERING How to match bolts and nuts Hole size is critical to tapping screws performance
FINISHING ASTM electroplating standard for threaded fasteners
HYDROGEN EMBRITTLEMENT Identifying failures
INSPECTING Fastener ultimate tensile strength explained What is dimensional conformity
THREAD ENGINEERING Coarse threads are generally better for assembly A thread’s “functional diameter” is its functional characteristic Only the GO size is different after plating on external inch threads
THREAD INSPECTION When two approved thread gages do not agree, is the thread acceptable
TIGHTENING Tightening the bolt or nut makes no difference What is the proper torque to be used on a given bolt
