Nylon Rivet Size Chart & Hole Guide

Nylon Rivet Size Chart & Hole Guide

How to Choose the Right Size for PCB and Electronic Assembly

Choosing the correct nylon rivet size is critical for ensuring secure fastening, efficient assembly, and long-term reliability in PCB and electronic applications.

Incorrect size selection can lead to:

• Loose mounting or component movement

• Difficult installation or damage to PCB

• Reduced retention strength

This guide provides a practical nylon rivet size chart and selection method for engineers and buyers.

 Standard Nylon Rivet Size Chart

Below is a general reference for commonly used nylon push rivets in electronic applications:

Note: Sizes may vary depending on design and manufacturer. Custom sizes are available.

Step-by-Step Selection Guide

1. Confirm PCB Hole Diameter

The rivet must match the hole size precisely.

• Too tight → difficult insertion

• Too loose → weak fixation

 Recommended tolerance: ±0.05 mm – ±0.1 mm

 2. Calculate Total Panel Thickness (Grip Range)

Grip range = total thickness of materials being fastened:

• PCB thickness

• Spacer (if used)

• Mounting panel

 Example:
PCB (1.6mm) + Spacer (2mm) + Panel (1mm)
= Total 4.6mm → select rivet with 3–5mm grip range

 3. Choose Rivet Type

Push-Type Nylon Rivets

• Fast, tool-free installation

• Ideal for automated assembly

Two-Piece Rivets

• Removable

• Suitable for maintenance applications

 4. Check Head Size and Clearance

Ensure the rivet head:

• Fits within your design space

• Provides enough holding surface

 5. Consider Retention Strength

Retention depends on:

• Material (PA66 vs reinforced nylon)

• Design structure

• Installation accuracy

 Common Application Examples

PCB Mounting

• Recommended hole: 3.0mm

• Typical grip: 1–3mm

 Fan & Heat Sink Fixing

• Requires higher retention

• Consider reinforced nylon material

 LED Modules

• Lightweight structure

• Smaller diameter rivets preferred

 Common Mistakes to Avoid

❌ Ignoring tolerance between hole and rivet
❌ Choosing incorrect grip range
❌ Using oversized rivets causing PCB stress
❌ Not considering assembly method (manual vs automated)

 When Standard Sizes Are Not Enough

In many electronic projects, standard sizes may not fit perfectly.
