The FIDLOCK SNAP male M retractable screw offers flush integration into your products. When combined with a female counterpart, magnetic force attracts the male part, causing the mushroom-shaped lock to emerge from the SNAP male M retractable and the fastener to lock securely. As soon as the female part is removed, the locking mechanism retracts, regaining the SNAP male M retractable fastener's flat surface. This version features a threaded ring for easy assembly. Naturally, the SNAP male M retractable offers the same quick, easy, and single-handed use as our other SNAP fasteners. The SNAP male M retractable is compatible with all SNAP female M components except for the SNAP female M screw (05500).
