There is provided a fastener for engaging with a loop fabric, comprising a base having a front surface with a multiplicity of engaging projections. At least some of the engaging projections having a top surface end and an attached end. The at least some engaging projections top surface ends form an edge angle surrounding the projections. A mantle surface extending from the top surface end edge to the attached end. Generally at least one contour line of a side view of the mantle surface is convex. There is also provided a first method for forming a fastener, comprising: dispersing polymer particle into a contact release surface transforming the polymer particles into an at least semiliquid state of a suitable viscosity for a time sufficient to transform into preform projections having contact edges contacting and fixing the front surface of the base with the terminal ends of at least some of the preform projections removing the base, thereby separating the preform projections, from the release surface forming engaging projections projecting from the front surface of the base.
