Screw Feeders for Nuts, Bolts & Hardware

The purpose of a screw feeder is to provide automated, controlled presentation and feeding of screws, fasteners, and hardware parts. By consistently regulating product flow from bulk containers, these systems eliminate manual part placement, protect interlocking components from damage, and ensure steady delivery into downstream processes such as secondary manufacturing operations, parts inspection, or automated packaging equipment.

Different types of hardware feeding systems include vibration feeders and custom gravity feed systems. Vibration feeders use controlled oscillating motion and open designs for interlocking, difficult-to-feed parts. Gravity feed setups utilize containers, dumpers, lift tippers, or lift truck rotators to supply secondary operations. The ideal type depends on part geometry, volume requirements, and specific manufacturing or packaging workflows.

A screw conveyor primarily transports bulk materials across a distance, whereas a screw feeder regulates and meters the flow of hardware into downstream equipment. In fastener and hardware handling, feeders focus on controlled discharge, part separation, and gentle presentation into weigh-count scales or workstations, rather than merely transferring bulk volume from one location to another.

Yes. Vibration feeders featuring open designs are engineered specifically for gentle handling of interlocking and difficult-to-feed hardware components. These systems separate tangled fasteners and control feed rates smoothly. Additionally, lift tippers enable gentle bulk loading directly into the feeder, minimizing part impingement and ensuring continuous presentation to downstream packaging fillers or workstations.

Hardware feeders can supply screws, fasteners, stampings, and forgings directly to various secondary manufacturing operations. These include parts washing, heat treating, plating, thread rolling, inspecting, and packaging. Custom-designed workstations and integrated dumpers or lift tippers ensure parts are delivered efficiently to each processing stage according to operational requirements.

Feeders integrate directly with automated packaging equipment, such as durable weigh-count fillers. Bulk hardware is loaded via lift tippers or gravity feed containers and fed at a controlled rate into the weighing or counting mechanism. This integrated setup streamlines packaging operations, reduces labor requirements, and maintains consistent packaging cycles for high-volume fastener operations.
