Ergonomic fastener

A fastener for securing a panel to a substrate, the fastener comprising:

• a pin portion having a head from which extends a shank;
• a body portion, the body portion having a flange from which extends a pair of legs, the legs being constructed and arranged for insertion into a bore formed in the substrate, the flange itself having a channel formed therethrough such that the channel passes between the pair of legs, the channel also being arranged to receive the shank of the pin portion therein such that as the shank is forced into the channel, the pair of legs are forced away from one another and into compressive contact with an interior surface of the bore formed through the substrate so as to secure the fastener, and subsequently the panel, to the substrate;
• and,
• an interference control mechanism formed as part of the exterior of at least one of the legs of the body portion of the fastener adjacent a base of the at least one leg of the body portion, the interference control mechanism acting to control the compressive strength of the at least one leg so as to limit the compressive contact between the at least one leg and the interior surface of the bore formed through the substrate, thereby controlling a required insertion force that must be applied to the pin portion of the fastener to seat the pin portion within the body portion of the fastener.
