This Proto 10-piece socket set features a 1/4" square drive with 12-point box-tip sockets ranging from 3/16" to 9/16", all forged from alloy steel with a nickel chrome finish for lasting durability. The 12-point design applies up to 15% more torque to the fastener while reducing the risk of rounding, making it ideal for professional MRO and mechanical applications.
Sockets mount on a ball-locking socket bar with included socket clips to keep everything organized and secure. The set is measured in inches and contains 10 sockets per bar — sold as 1 complete set.
