Common Mistakes

Rivets are simple to install, but small errors can lead to weak joints, misalignment, or failed assemblies in FRC robots. 

 

 Incorrect Hole Size 

 

 Using a hole that is too large reduces holding strength 

 Using a hole that is too small can deform the rivet or prevent installation 

 

 Always match the drilled hole size to the rivet specification. 

 

 Wrong Grip Range 

 

 Too short → rivet may not fully set or can pull out 

 Too long → joint will be loose and weak 

 

 Grip range must match the total material thickness. 

 

 Poor Alignment 

 

 Rivets installed at an angle weaken the joint 

 Misaligned holes can cause stress on the connection 

 Parts may not sit flush against each other 

 

 

 Not Deburring Holes 

 

 Sharp edges can prevent proper seating 

 Burrs may interfere with rivet expansion 

 Can lead to uneven or weak joints 

 

 

 Incomplete Setting 

 

 Rivet not fully pulled can loosen over time 

 Mandrel should snap cleanly when properly installed 

 

 

 Overusing Rivets 

 

 Using too many rivets can add unnecessary weight 

 Can weaken material if holes are too close together 

 

 

 Key Idea 

 Strong riveted joints depend on correct hole size, proper grip range, clean installation, and good alignment. Most rivet failures come from small setup mistakes rather than the rivet itself.
