The Hilmor Reversible Magnetic Nut Drivers incorporate a high performance socket design that drives the fastener from the flats, not the corners, minimizing slippage. It features a tapered socket design for improved access in tight spaces and uses a 1/4-inch magnetic hex shaft, where metal shavings and debris are easily wiped off. The socket quickly changes between 1/4" and 5/16" sizes, and is available in 3 standard lengths. The sockets are forged from 6150 Alloy Steel and hardened above 48 HRC for improved strength and durability making it the ultimate switchbit. Hilmor Reversible Magnetic Nut Drivers meet or exceed ASME B107.110 Standards.
