The magnetic parts trays are ideal for storing small tool, screws, pins and any other ferrous items and keep them within reach of work area.  They help prevent lost or misplaced parts, fasteners, and tools.  Mount tray horizontal, vertical, or upside down to hoods, fenders, or other ferrous metal surfaces.  Rubberized covering over magnet prevents damage to finished surfaces.
