Speedway 3/16 Small & Large Head Alum Exploding Rivets, Black

Ok, they don’t really explode, but the back side splits into folds so you don’t normally need to use a back-up washer with them. They work great where it’s hard to reach the back side. Includes both large and small headed rivets. Box of 250 Large. Box of 250 Small. Small head is 3/8 O.D. Aluminum pop rivet with aluminum shank. Grip range from 0 to 3/8"
