A fastener, capable of securing work pieces accessible from only one side, is provided. The blind fastener includes a deformable sleeve and a pin, the pin having a main body section and a tail section. The main body section includes a shear load bearing section integrally connected to a lock collar engagement section on a first end and a pin stalk section on a second end, the pin stalk section integrally connected to a series of pin sleeve integrating grooves. The tail section is integrally connected between the main body, via a break notch, and a series of serrations. The sleeve includes a hollow tubular shank having a first sleeve end and a second sleeve end, where the first sleeve end has a sleeve head having an opening for receiving the main body section. At all times during assembly of the fastener, the series of serrations remain outside the sleeve, never passing through the sleeve.
