The Perfect Pull: Why Jaws Matter
It’s not magic — it’s engineering perfection in every pull.
When you pull the trigger on a rivet gun, you might think it’s all about brute force, but the real precision lies in the jaws. These small, hardened steel components are the unsung heroes of every perfect fastening. They grip, pull, and release the rivet stem with astonishing accuracy and when they wear out, even the most powerful rivet tool can lose its edge.
⚙️ The Hidden Power Inside Your Rivet Tool
Every time you set a rivet, the jaws inside your rivet gun clamp down on the mandrel with pinpoint precision. They convert the tool’s pulling force into the perfect tension needed to snap the rivet stem at exactly the right moment.
Too tight and you risk damaging materials. Too loose and your rivet won’t set properly.
This delicate balance is why brands like Gesipa, POP Avdel, and Rivrite have invested years into perfecting jaw design and material composition. Each jaw set is engineered for a smooth, consistent pull, whether you’re using a battery-powered rivet tool or a hydro-pneumatic rivet nut tool.
🧩 How Jaws Work: Grip. Pull. Release.
-
Grip: As you activate the trigger, the jaws close around the mandrel, holding it securely in place.
-
Pull: The tool’s mechanism retracts the jaws, pulling the mandrel to deform the rivet body.
-
Release: Once the stem snaps, the jaws release, ready for the next cycle.
It’s a seamless sequence that happens in fractions of a second, precision you can feel in every pull.
🔧 Why Tool Spares Matter
Even the best jaws wear down over time. Regular maintenance and timely replacement of tool spares, including jaws, collector bottles, nosepieces, and mandrels, can make all the difference between flawless rivets and frustrating rework.
