Note 1: The recommended ring lug connector listing consists of wire size – screw size
format. The wire sizes are in AWG or mm
for the ring lug centers are: #10, #12, 1/4", 5/16", and 1/2". For metric wire sizes, bolt
sizes for the ring lug centers are: 6 = 6M, 8 = 8M, 10 = 10M
TIP: AWG = American Wire Gauge. Smaller numbers represent increasing wire thickness.
