ABSTRACT
Sometimes a designer will propose a combination of rivets and bolts or bolts and dowel pins to share a shear load. This is not an acceptable design. Rivets are hole-filling (interference fit). Dowel pins are slip or snug fit, and bolts have clearance holes. Therefore, any combination of these three types of shear fasteners will give uneven load distribution, with the tightest fasteners picking up most of the load first.
