SB0704E 2 oz (57 g) Ground Pin Compliant with UL 498 Figure 119.3

The SB0704E 2 oz (57 g) Ground Pin, compliant with UL 498 Figure 119.3, is meticulously engineered to adhere to the revised March 15, 2006 standards. It features a precise 2 oz (57 g) configuration, with dimensions, tolerances, material properties, hardness, and surface roughness all meeting stringent regulatory requirements. The material’s low thermal expansion coefficient ensures stable dimensional accuracy. Key structural details include a 0.5 inch (12.7mm) diameter section, a spherical full radius on the tip measuring 1845 inch (4.69mm), and essential length dimensions of .797 inch (20.24mm) and .792 inch (20.12mm). The designated grinding direction is critical for maintaining precision. This gauge is vital for verifying the structural and dimensional compliance of plugs and sockets.
