Frequently Asked Questions

How is rivet length calculated? +

Rivet length is calculated using the formula: Plate1 Thickness + Plate2 Thickness + 1.5 × Rivet Diameter. This ensures proper formation of the rivet head on the opposite side.

What is grip range? +

Grip range refers to the combined thickness of materials that a rivet can effectively join. It’s important to select a rivet with a grip range that matches your material thickness for optimal performance.

How do I determine the correct hole size? +

Hole size is typically 0.1-0.3 mm larger than the rivet diameter for standard rivets. The exact tolerance depends on the rivet type and material. Our calculator provides precise recommendations based on industry standards.

What factors affect edge distance and spacing? +

Edge distance (distance from rivet center to material edge) should be at least 2 times the rivet diameter. Rivet spacing (distance between rivets) should be at least 3 times the rivet diameter. These values may increase for structural applications.
