3 mm Pop Rivets
3 mm Pop Rivets refer to pop rivets with a shank diameter of 3.0 mm, suitable for thin sheet metal connections and light-duty structural assemblies. This size effectively minimizes deformation of the connected materials while ensuring fundamental joint strength. Commonly used in industrial applications demanding weight reduction, aesthetic appeal, and assembly precision.

What Does “3 mm” Mean in Pop Rivets?
3 mm refers to the rivet’s shank diameter, not the pre-drilled hole diameter.
The shank diameter determines the rivet’s fundamental strength level and suitable application scenarios.
The pre-drilled hole size is typically slightly larger than the shank diameter.
For a 3.0 mm blind rivet, the commonly recommended hole diameter range is 3.1–3.2 mm, depending on the rivet design and material.
3 mm and 1/8″ (3.2 mm) are closely related in practical applications but are not entirely equivalent.
They may serve as alternatives in certain light-load applications, provided hole diameter, tolerances, and clamping range compatibility are verified.
Accurate differentiation between shank diameter and hole diameter helps prevent assembly defects and batch installation inconsistencies.
Misunderstanding dimensions is a common cause of riveting failures and rework.

HOW TO CHOOSE
3 mm Pop Rivets vs Other Common Rivet Sizes
3 mm vs 1/8" Pop Rivets
| Comparison Aspect | 3 mm Pop Rivets | 1/8″ Pop Rivets (≈3.2 mm) |
|---|---|---|
| Strength Level | Suitable for light to medium load fastening | Typically offers slightly higher load capacity |
| Typical Applications | Thin sheets, electronic enclosures, light-duty assemblies | Sheet metal parts, general industrial fastening |
| Weight & Drilling Requirement | Smaller hole size, lower impact on base material | Slightly larger hole size, more noticeable impact on thin sheets |
In certain light-load applications, 3 mm may serve as an alternative to 1/8″, but it is essential to verify that the hole diameter, tolerances, and clamping range meet assembly requirements.
3 mm vs 4 mm Pop Rivets
| Comparison Aspect | 3 mm Pop Rivets | 4 mm Pop Rivets |
|---|---|---|
| Strength Level | Suitable for light-duty fastening | Suitable for medium to higher load applications |
| Typical Applications | Thin sheets, lightweight components | Structural parts, applications with higher load requirements |
| Weight & Drilling Requirement | Lightweight, smaller drilling diameter | Larger drilling diameter, greater impact on base material |
When the connection point is sensitive to weight, appearance, or thin sheet deformation, 3 mm is typically the more suitable choice; if structural strength is the priority, evaluate whether an upgrade to the 4 mm specification is necessary.

FAQs - 3 mm Pop Rivets
Q1: Is 3 mm the same as 1/8 inch?
Not exactly. 3 mm refers to the metric shank diameter of the rivet, while 1/8 inch is approximately equal to 3.2 mm. In some light-duty applications, 3 mm can serve as an alternative to 1/8″, but verify that the hole size, tolerances, and clamping range are compatible.
Q2: What hole size is required for 3 mm pop rivets?
The generally recommended pre-drilled hole size is 3.1–3.2 mm. The specific hole diameter should be confirmed based on the rivet design, material combination, and assembly requirements.
Q3: What is the MOQ?
Minimum order quantities vary based on rivet type, material combinations, and customization requirements. For standard 3 mm pop rivets, we offer flexible MOQ arrangements, which can be confirmed upon inquiry.
Q4: Can open end blind rivets be used outdoors?
A: In outdoor environments without waterproofing or gas-tight requirements, open end blind rivets made from suitable materials (such as stainless steel or corrosion-resistant alloys) are viable. However, for prolonged exposure or highly corrosive conditions, careful evaluation is needed, or alternative rivet types should be selected.
Q5: Can you provide samples?
Yes. We can supply samples tailored to your specific application for assembly testing or performance verification. Sample specifications and quantities are negotiable based on your requirements.
