The SNAP male S retractable screw sits flush in your product for a clean look. Paired with a female counterpart, magnetic force triggers the mushroom-shaped lock to extend and secure the fastener. Once the female part is removed, the lock retracts, returning the surface to flat. This version includes a threaded ring for easy assembly and offers the same quick, one-handed use as our other SNAP fasteners. It is compatible with all SNAP female S components.
