Handy sets fit your pocket or tool box easily and help eliminate the lost-key problem. Tough, heat-treated alloy steel. Hex-key ends are square-cut for a secure full-depth fit and maximum contact with the hex socket to prevent slippage and stripping of the socket. Holder serves as a handle. Two key positions (straight-out or right angle) for extra leverage. Ball design allows for a thicker neck diameter increasing torque capacity while maintaining operational angles to 25%. Set includes 3/16, 7/32, 1/4, 5/16 and 3/8 inch.
