The Ultra-Fast Fully Insulated FASTON Series is a 12-10 AWG Receptacle and Tab offers the advantage of a completely protected terminal and a wire crimp with comparable electromechanical performance to open barrel “F” crimp FASTON Terminals.

The “User-Friendly” design combines easy mating with rounded corners. The .187 and .250 series receptacles incorporate a two-stage roll configuration and a cantilever mounted dimple which provides easy insertion and multiple independent points of contact for reduced tab interface resistance.
