The SNAP male S retractable anchor sits flush in your product for a seamless 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 an anchor add-on for easy assembly in thick materials like wood. It offers the same quick, one-handed use as other SNAP fasteners and is compatible with all SNAP female S components. The stated static breaking load applies when used with female products FL-05516 and FL-05517.
