52921 is a PLASTI-GRIP nylon-insulated ring tongue terminal designed for solderless wire termination in electrical applications. This terminal accommodates 26-22 AWG wire sizes (202-810 circular mils / 0.10-0.41 mm²) and features a #2 (M2) stud size with yellow color-coded insulation for easy identification. The terminal body is constructed from phosphor bronze per ASTM B-139 with a copper metallic sleeve per ASTM B-152 and tin plating per ASTM B-545, providing excellent conductivity and corrosion resistance. The nylon insulation is rated UL 94V-2 and offers high dielectric strength, while the serration feature inside the terminal barrel ensures exceptional contact and tensile strength. This terminal is ideal for control circuits and general-purpose wiring applications requiring reliable, high-quality terminations.
