Abstract
A screw for use in joining workpieces, for example automotive body parts, is provided that includes a head portion, an externally threaded shank extending from the head portion, a flow-hole-forming tip disposed at a distal end portion of the externally threaded shank, and a recessed spring washer disposed under the head portion. The recessed spring washer is configured to apply a clamping load to joined workpieces as they expand and contract.
