Safety flush rivet set makes it virtually impossible to damage or “smile” the skin while flush riveting. Rubber outer guard cushions the outer edge of the set while limiting recoil. Swivel head will move through 20 degrees to keep the face of the set flush against the head of the rivet which minimizes mis-setting the rivet. Finally, the safety spring keeps the set securely attached to the rivet gun to prevent accidental “bullets.”
