Abstract
A fastening system including a two piece swage type fastener including a pin and a collar in which the pin has relatively wide lock grooves and in which the lock grooves have a generally smooth root contour with the collar having a shank portion with a wall thickness defining an excess volume of material prior to swage greater than the volume of the confronting lock grooves and with the clearance between the inside diameter of the collar shank portion and the diameter of crests of the lock grooves being a minimum to reduce the compressive force required to swage the collar shank into the lock grooves and with the excess volume of collar shank material providing only a partial fill of the lock grooves upon swage.
