Visual indicator for turn-of-nut torque application

A socket for a turn-of-nut torque application comprising an elongated body portion having a drive end portion and a nut end portion opposite from said drive end portion:

• said drive end portion having an interior recess configured for accepting a drive end of a tool;
• said nut end portion having an interior recess configured with a polygonal cross-section, said polygonal cross-section having at least one interior corner for engaging a nut and transmitting force to the nut;
• said elongated body portion being configured as a tube-like body portion having an interior surface and an exterior surface defining a socket wall, said exterior surface being cylindrical and comprising at least one visual indicator for indicating turn-of-nut position,
• said at least one visual indicator being precisely machined into said exterior cylindrical surface of the elongated body portion,
• said at least one visual indicator comprising a first portion proximal an exterior edge of the nut end portion and a second portion distal said exterior edge of the nut end portion, and wherein said at least one visual indicator on said exterior cylindrical body portion is positioned directly opposite said at least one interior corner of said nut end recess, said at least one visual indicator and said at least one interior corner having a common socket wall portion.
