A wing nut includes a body having a sidewall that surrounds a central opening. The central opening is threaded along a threaded portion having a threaded length extending from the back end towards the front end of the body. At least two wings are integrated with the sidewall and extend away from the sidewall in a radial direction relative to the centerline. A rib extend peripherally around the sidewall in a radially outward direction such that a wall thickness of the sidewall increases to a maximum value moving along the centerline away from the rear end, and decreases along the centerline moving towards the front end from the maximum value.

Method of producing a narrative analytical report. The system analyzes information which has been input to a database and, using predetermined phrases intermingled with extracts from the database, produces a narrative analytical report which describes the critical aspects of the database. The system also produces a listing of questions on those aspects of the database which require explanation of clarification. In the final output, the user's responses to the questions are integrated into the appropriate areas of the analytical report.
