The invention provides a radially expanding fastener/alignment plug assembly for use with a torque power tool, the assembly including: a sleeve member (), insertable into a hole of an object, having radial expansion elements with inner surface portions which are tapered towards a first end; an expanding member (), insertable in the sleeve member, having an outer surface portion which is tapered towards a first end, cooperating with the inner tapered surface portions of the radial expansion elements of the sleeve member; and a displacement member () formed between a second end of the sleeve member and a second end of the expanding member. Advantageously, the assembly is self-reacting allowing an actuation torque to be applied to and reacted upon to create high levels of pulling and expansion force without the need for an external reaction point.
