These aircraft rivet sets are high-alloy steel, and heat-treated to provide for structurally sound driven aluminum rivets. These are AN470 rivet sets.
Excellent quality at lower cost! Purchasing these as a 5-piece set saves cost over buying each set individually. In addition, this is a great starter set for bucking AN470 aluminum rivets, as it contains four common sizes plus a flush rivet set. Usage includes universal and flush-style rivets.
The shank is precision-ground to the industry standard .401 shank.
