Abstract: An exemplary fastener feeder includes a pair of guiders, a slot cover and a blocker. The guiders define a sliding slot therebetween. Each guider includes a sloped part and a level part, bodies of the fasteners are capable of being received in the sliding slot, and a head of each fastener is capable of sliding down from the sloped parts and stopping on the level parts. The slot cover defines an opening for providing a path through which a fastener pickup device can pass through and engage with a fastener located on the level parts. The blocker is located below the level parts. When the fastener pickup device moves the fastener head engaged therewith away from the opening and a length of the fastener is greater than a distance between the blocker and the level parts, the fastener is blocked by blocker and disengaged from the fastener pickup device.
