23-Piece 1/4 in. Drive 6-Point SAE and Metric Magnetic Impact Socket Set Grey Pneumatic supplies the world's automotive, industrial, assembly, mining, maintenance, construction and energy industries with heavy-duty, high quality impact and specialty sockets. GP sockets and tools are made using the highest quality chrome-molybdenum alloy steel and state-of-the-art manufacturing process and equipment. Through and exact heat treatment, as well as rigid quality control, ensures the correct balance of strength and durability to deliver outstanding performance at the most competitive cost. . Designed for professional tool users and made of high quality alloy steel Engineered specifically for use with impact tools Made to transfer the pressure from the thinnest part of the socket wall toward the thicker section, resulting in increased strength High torque drives limits the amount of wear on the corners of the fastener and the socket improving the strength of the socket, and transferring increased torque to the fastener allowing easier access to tight areas Has a spring loaded magnet that retracts into the socket for extended bolt applications . 3/16 in. 6-Point SAE Magnetic Impact Socket - 906RG 7/32 in. 6-Point SAE Magnetic Impact Socket - 907RG 1/4 in. 6-Point SAE Magnetic Impact Socket - 908RG 9/32 in. 6-Point SAE Magnetic Impact Socket - 909RG 5/16 in. 6-Point SAE Magnetic Impact Socket - 910RG 11/32 in. 6-Point SAE Magnetic Impact Socket - 911RG 3/8 in. 6-Point SAE Magnetic Impact Socket - 912RG 7/16 in. 6-Point SAE Magnetic Impact Socket - 914RG 1/2 in. 6-Point SAE Magnetic Impact Socket - 916RG 5mm 6-Point Metric Magnetic Impact Socket - 905MG 5.5mm 6-Point Metric Magnetic Impact Socket - 955MG 6mm 6-Point Metric Magnetic Impact Socket - 906MG 7mm 6-Point Metric Magnetic Impact Socket - 907MG 8mm 6-Point Metric Magnetic Impact Socket - 908MG 9mm 6-Point Metric Magnetic Impact Socket - 909MG 10mm 6-Point Metric Magnetic Impact Socket - 910MG 11mm 6-Point Metric Magne
