Thesetwo flanges at right angles with the body of the fastener, bothbeing made in (he process of manufacture, render it unnecessaryto do any driving or forming in applying this device other thanwould be necessary ir. applying a common wrought washer. Thisdevice saves much labor and is meeting with popular Figure 2 shows the application of both the bolt fastener and archbar style nut lock above mentioned.
