These came from the buyout of Dixie International when they went out of business. Not sure what brand of motorcycle these were used on, so I'm going to give you specifications to see if they're going to work for your particular application. The head of the black plastic knob is about 1.75 in. in diameter . The overall length is about 1.75 in. The threads are about three quarters of an inch. The thread size is M 8-1 .25. We believe they were used to hold on side covers to 1960s and early 1970s Japanese motorcycles. We took a picture of the packaging for the nut to show you what size threads the stud is. You will not be getting the nut, we only took a picture to show you that we checked the sizing. We are selling them in lots of 10. Although these are new they've been sitting in a warehouse for decades so expect some dust and minor scratches. There's a handwritten label as you can see in one of the pictures. It is M100– 05.
