What is Rivet Length?

Rivet length is the total length of the rivet required to securely join two materials. It is calculated based on the thicknesses of the materials being joined and the diameter of the rivet stem.

User Guide

To use the Rivet Length Calculator is simple:

  1. Enter the thickness of material 1 (T1) into the calculator.
  2. Enter the thickness of material 2 (T2).
  3. Enter the diameter of the rivet stem (D).
  4. The calculator will provide the required rivet length (RL).

Example Input Values:

  • Thickness of Material 1 (T1): 0.5 inches
  • Thickness of Material 2 (T2): 0.3 inches
  • Diameter of Rivet Stem (D): 0.1 inches

Rivet Length Formula

To calculate the rivet length, use the following formula:

RL=(T1+T2+1.5×D)\text{RL} = (T1 + T2 + 1.5 \times D)


Variable Description
RL Rivet Length (inches)
T1 Thickness of Material 1 (inches)
T2 Thickness of Material 2 (inches)
D Diameter of Rivet Stem (inches)

How to Calculate Rivet Length

Following is an example calculation for rivet length using the formula.

1 . Add the thicknesses of Material 1 and Material 2.

T1+T2=0.5+0.3=0.8T1 + T2 = 0.5 + 0.3 = 0.8

2. Multiply the diameter of the rivet stem by 1.5.

1.5×D=1.5×0.1=0.151.5 \times D = 1.5 \times 0.1 = 0.15

3. Add the results from the first and second steps.

RL=0.8+0.15=0.95RL = 0.8 + 0.15 = 0.95

Thus, the required rivet length (RL) is 0.95 inches.

Calculation Examples

Example Type Input Values Rivet Length
Basic T1: 0.5 in, T2: 0.3 in, D: 0.1 in 0.95 in
Advanced T1: 0.8 in, T2: 0.5 in, D: 0.15 in 1.325 in
