Keep all your 3/8-inch drive sockets organized with the STEELMAN 42035 magnetic organizer. The soft rubberized covering on the bottom of this organizer prevents damage to finished surfaces and does double duty by both allowing the holder to be mounted on any ferrous metal surface and keeping held sockets securely in place. The organizer is designed to hold a total of 12 standard/SAE and metric sockets. The durable plastic construction is oil and fuel resistant and the smooth surface is easy to wipe clean when soiled. In addition, the magnetic material used is non-transferrable and will not magnetize held sockets or surfaces/tools it comes in contact with.
