These rivets are from Zenair and are suitable for installation using either hand or pneumatic riveters. The A4 and A5 rivets must be installed using a machined head for correct fitting (as per the Construction Standards from Zenair)
A3 and A6 rivets can be installed using a standard flat rivet head tool.
A5S is the STAINLESS STEEL rivet option and we recommend dipping the rivet in Cortec or a similar treatment prior to installation (pull with product wet for best results)
