Red folding riveting gun

A folding riveting gun, also known as a “lazy tong” or “accordion” riveter, is a specialized manual hand tool used to install rivets, particularly in situations where more leverage is required than a standard hand riveter can provide. The folding design gives it a significant mechanical advantage, making it easier to set rivets, especially larger or tougher ones, with less physical effort.

Key Characteristics

• Folding/Accordion Design: This is the defining feature. The long handles fold and unfold in a scissor-like or “lazy tong” action. This design allows you to apply force over a greater distance, which multiplies the force applied to the rivet, making the job much easier.
• High Leverage: The extended length and folding mechanism create a powerful leverage system. This is what distinguishes it from a simple, one-handed rivet gun and makes it a “heavy-duty” tool. It’s particularly useful for setting rivets in harder materials like steel and stainless steel.
• Versatility: Most folding riveters come with multiple interchangeable nose pieces to accommodate a range of rivet sizes. This allows you to use the same tool for different applications and materials. Common rivet sizes it can handle include 3.2mm, 4.0mm, 4.8mm, 6.0mm, and 6.4mm.
• Portability: Despite its size and power, the folding design makes it more compact for storage and transport compared to other high-leverage riveting tools.
• Durability: These tools are typically constructed from heavy-duty materials like steel or aluminum alloy to withstand the high forces involved in riveting.
