Traditional nut and bolt fasteners are generally acceptable but will normally be over specified for particular applications. Thus, in situations where weight is important such traditional nut and bolt fasteners are not optimised. By providing a fastener in which splayed arms are created with ridges in respective receptor members and insert arm members it will be understood that multi point stabilised contact points for a nut are provided. Thus, the nut can move along the ridges defining a screw path for tightening of the fastener in use. The engagement between the receptor members and the insert arm members is typically through a slot forked end or a closed slot with the slots presenting the splayed arms perpendicular to each other in a cruciform configuration.
