The Effect of Nut Design on the Fatigue Life of Internal Wrenching Bolts

摘要

This evaluation demonstrated the wide range of fatigue life that may be obtained with internal wrenching bolts, depending upon the use of different type nuts. The effects of individual design factors such as height of nut, strength of nut, use of lubricants, angularity, tightening torque, etc., were quantitatively determined. Recommendations are made concerning the development and evaluation of specifications for nuts and bolts, and their use in military aircraft design and construction. (Author)
