ABSTRACT:
An improved connection assembly which saves space and eliminates the need for many conventional fastener means such as nuts and flanges. The assembly includes a receptacle for accepting and engagement member, wherein a small amount of clearance is present between the receptacle and the engagement member. The engagement member includes a slot having two substantially parallel surfaces. A threaded fastener is used to fix the engagement member within the receptacle by passing the fastener through an opening in the bottom of the receptacle and causing the threads of the fastener to cut into and engage the surfaces of the slot.
