💡 What is a blind rivet and how does the tri-fold design improve clamping in oversized holes?

Here's a handy answer for common questions:

• Blind rivets join materials from one side by forming a head behind the workpiece.
• The tri-fold mandrel expands to bite into irregular holes, increasing holding power.
• No backer washer is required because the tri-fold action locks the rivet tight.
• This setup works well in automotive repair, machinery maintenance, and metal fabrication.
