The Milton Industries 4-pc 1/2" Drive Deep Thin Wall Flip Socket Set, No. 1300-SS-10, is crafted from cold-forged Cr-MO steel to endure vibrations and impacts, preventing damage and extending both socket and anvil tool life. The 6-point lock-on design allows for a pinless connection for distributing high-torque with professional strength, keeping fasteners from getting damaged. With high-visibility laser etchings, users can easily find the correct size they need, even in dim conditions. Chamfered openings facilitate connection between the drive tool and the fastener. The set includes 1" deep 6-pt 3/4" by 13", 19mm by 21mm, 7/8" by 15/16" (metric and SAE) impact sockets, and a 3" impact extension.
