A fastening element features a female cap member and a unitary stud body defining a flexible base portion and a projecting portion integral therewith. A peripheral rim of the projecting portion stands upwardly from the base portion and is engageable into the female cap member as a snap fastener, and a bottom surface of the flexible base is deformable relative to the projecting portion. A layer of adhesive is sandwiched between the bottom surface of the flexible base portion and a removable covering layer for adhering to a surface on which stud is to be mounted. The one piece stud body can be produced efficiently while its flexible base is adaptable to mount on any of a variety of differently shaped surfaces, such as non-planar surfaces of a vehicle body to allow selective securing of a fabric cover on the vehicle via a corresponding female cap secured on the cover.
