Grey Pneumatic 4124D 3-7/8 Deep Socket
Grey Pneumatic 4124D is a 1-inch-drive deep impact socket with a listed 3-7/8-inch fastener opening. The specification distinguishes a 2.28-inch socket depth from a 5.51-inch overall length, and identifies chrome-molybdenum steel. Check those dimensions separately: the nominal opening fits the fastener, while depth and total length determine how the socket reaches and clears the assembly.

Before ordering
