|These rivet sets are used for back riveting flush rivets on RV control surfaces and other homebuilts. The spring loaded pressure holds the rivet firmly against the skin surface when flush riveting. These tools are also used to "back rivet" the rivet shank when the rivet head surface is inaccessable. Features a plastic sleeve to hold multiple sheets of aluminum together while riveting. 0.401 shank.|
I used it appx. 50 times and the pins came out of it.
One of the best tools I ever purchased! Keeps panel to panel TIGHT, plus creates a very uniform and nice looking rivet when you're done. Only gripe? I wish they made many lengths and offsets so I could use it in difficult places to reach. MUCH better result than a flush head on the gun and ANY bucking bar. Can I rate it SIX Stars?
