The specifications call for a #11 drill (0.190"-0.200") diameter pilot hole. However a 3/16" can sometimes be used as they tend to oversize when drilled by hand. These rivets have an extremely long grip range of 0.030" to 3/8". Both the flange and mandrel are of aluminum construction. These rivets are BLACK in color (only the head and shank, the 1/8" mandrel is mill finish). The head diameter is 1/2" minimum. The finished head height after installation is about 0.062" The rivets go by many names such as EXPLODING, TRI-FOLD, or MULTI-GRIP. This rivets achieve this characteristic by splitting three ways on the back when installed . This allows for installation in blind holes such as tubing or on body panels where access to the back side is limited. The tri-fold action eliminates the requirement of a backing washer. These are must have for your handy-man tool box. Also works for repairing gutters, storm doors, hinges and many other items where a blind hole is present. As with any fastener installation, at a minimum always wear safety glasses/goggles, gloves, and closed toed shoes. You should also take any other precautions you feel are required with your work area. ProductSiteLaunchDate : 2019-05-01T01:32:54.022Z Size : 50pcs UnitCount : 1 UnspscCode : 31162201
