The Boltster Multi-Hex Fastener Organizer provides a flexible solution for organizing fasteners ranging from 4 mm to 20 mm in a single tray. Its continuous hex layout accommodates multiple fastener diameters, lengths, and thread types, reducing the need to switch between organizers during repairs. Six integrated rare-earth magnets secure small fasteners and allow the tray to attach to steel surfaces, including vertical and overhead positions. Made from heat-resistant silicone rated to 500 degrees F, the 15" by 10" organizer also resists oils, fuels, and shop solvents.
