165028 is an AMP PIDG ring tongue terminal designed for electrical connections in wire sizes 4.0–6.0 mm² (AWG 12–10). The terminal features a tin-plated copper conductor with a nylon insulation sleeve, providing corrosion resistance and reliable electrical contact. It is configured for M6.0 bolt connection with a 6.3 mm stud hole diameter. The terminal dimensions include a thickness (S) of 1.0 mm, width (W) of 12.7 mm, contact width (C) of 8.7 mm, and maximum length (L) of 29.9 mm, with an insulation diameter of 6.4 mm. This ring tongue terminal is commonly used in automotive, industrial, and power distribution applications where secure, low-resistance connections are required for medium to heavy-gauge wiring.
