Like some reviewers this is not a 10gauge lug.Inside barrel dia. measures .165 to .171in. not .125(1/8")in. 10gauge stranded wire is .116in. dia. 8gauge is .146in.dia.according to online gauge chart.The eye thickness is thin .035in.as compared to a standard auto store yellow #12-#10 eye connector which measured at .045in. thickness.Another seller on Revain has there 10gauge lug charted at 1.3mm which .051in.thickness with some mixed reviews.The pictures for this product are deceptive and product looks heavy duty.Not UL listed.Would not trust product for 10gauge amperage rating.
