Wholesale 4.8 mm Pop Rivets
4.8 mm Pop Rivets are the specification of blind rivets used for higher strength and structural connections. This size is equivalent to 3/16″ in the imperial system and is a very common industrial standard in the European and American markets. Compared to the 4.0 mm specification, 4.8 mm typically has a higher load-bearing capacity and is more suitable for assembly applications with higher requirements for load-bearing areas and long-term stability.
- Higher structural connection strength
- More stable long-term assembly performance
- More suitable for project and batch production requirements
What Does 4.8 mm (3/16") Mean in Pop Rivets?
In blind rivets, 4.8 mm refers to the shank diameter of the rivet, not the diameter of the pre-drilled hole. The shank diameter is a key parameter that determines the rivet’s load-bearing capacity and applicable working conditions.
In the imperial system, 4.8 mm is equivalent to 3/16 inch, which is a widely used standard specification in industrial assembly in Europe and America. Therefore, “4.8 mm pop rivets” and “3/16 blind rivets” usually refer to the same type of product.
Compared with the 4.0 mm specification, the 4.8 mm one, due to its larger rod diameter, usually has higher tensile and shear load-bearing capacity under the same material conditions. This is a common reason for upgrading in engineering design. However, correspondingly, a larger rod diameter usually means a larger pre-drilled hole size. This will have a more obvious drilling impact on thin plates. Therefore, when selecting, the thickness of the plate and the strength of the hole position should be considered together.
Due to their higher strength and better structural stability, 4.8 mm (3/16″) blind rivets are more suitable for load-bearing sheet metal structures, equipment frames, support systems, and industrial connection scenarios that require long-term reliability.

HOW TO CHOOSE
4.8 mm (3/16") Pop Rivets vs 4.0 mm and 6.4 mm: How to Choose the Right Size
4.8 mm vs 4.0 mm: When Should You Upgrade?
- Strength Level: The 4.8 mm (3/16″) diameter is larger and typically offers higher tensile and shear bearing capacity compared to 4.0 mm, making it more suitable for load-bearing structural connections.
- Bore Diameter and Drilling Impact: The 4.8 mm requires a larger pre-drilled hole size, which has a more significant impact on thin plates, but can result in a more stable riveting effect.
- Typical Load Scenarios: The 4.0 mm is more suitable for general medium-load assemblies, while the 4.8 mm is better suited for higher load scenarios such as equipment frames, support systems, vehicle components, etc.
- Upgrade Recommendation: When there is loosening, insufficient strength, or insufficient safety margin at the 4.0 mm riveting points, upgrading to 4.8 mm is a common and reasonable engineering choice.
4.8 mm vs 6.4 mm: When Does 6.4 mm Represent Excessive Engineering?
- Strength Level: 6.4 mm is typically used for connections with higher loads and thicker plates, and its strength grade is significantly higher than 4.8 mm. However, not all projects require this.
- Bore Diameter and Drilling Impact: The 6.4 mm drilling size is larger and has a more significant impact on thin plate materials. It also increases processing costs and assembly difficulty.
- Typical Load Scenarios: 6.4 mm is more commonly used for heavy-duty structural components, high impact loads, or connection areas with high safety requirements.
- Selection Recommendation: If the application scenario is for routine industrial assembly or medium-high load structural connections, 4.8 mm is usually sufficient; only when there are clear high load or higher safety requirements should 6.4 mm be considered.
Selection Recommendation: A Practical Guideline
- Choose 4.0 mm: This option is more suitable when the aperture is strictly limited and the load requirement is not high.
- Choose 4.8 mm (3/16″): This is the more balanced standard specification when higher strength, better stability, and control of the drilling impact are needed.
- Choose 6.4 mm: This option is more appropriate for projects with obvious high load, thick plates, or strong vibration and impact conditions, and when a higher safety margin is required.

FAQ About 4.8 mm (3/16") Pop Rivets for Industrial Projects
Q1: Is 4.8 mm the same as 3/16 inch?
Yes, 4.8 mm and 3/16 inch usually refer to the same specification in the industrial fastener field. 3/16″ is the standard size commonly used in the European and American markets, while 4.8 mm is the metric expression. Both can often be understood interchangeably during procurement and selection, but it is still recommended to follow the product drawings or standard specification tables when placing orders.
Q2: What hole size is required?
The pre-drilled hole size for 4.8 mm (3/16″) blind rivets is usually slightly larger than the rod diameter. The common recommended range is 4.9–5.0 mm. The specific hole diameter needs to be confirmed in conjunction with the rivet structure, material combination, and assembly process. A too small hole diameter will cause installation difficulties, while a too large hole diameter may affect the riveting strength and clamping stability.
Q3: Is 4.8 mm stronger than 4.0 mm?
This is usually the case. The 4.8 mm diameter rod is larger. Under the same material conditions, the overall tensile force and shear bearing capacity are often higher than those of 4.0 mm. Therefore, it is more suitable for load-bearing structural connections, vibration environments, or industrial assembly where higher safety margins are required. However, the actual strength still depends on the material combination and the design of the rivet structure.
Q4: Can 4.8 mm replace 4.0 mm?
In many cases, it can be replaced, but it is necessary to confirm whether the hole diameter can be enlarged and whether the thickness of the sheet is suitable for larger-sized rivets. If the original structure has problems such as insufficient strength, loosening, or unstable connections, upgrading to 4.8 mm is a common engineering solution. However, if the hole size is fixed or the thickness of the thin sheet is low, the assembly conditions need to be re-evaluated.
Q5: Can you provide samples for testing?
Yes. We can provide 4.8 mm (3/16″) blind rivets as samples for customers to conduct assembly verification and strength tests. The sample specifications can be matched according to the plate thickness, material combination and head type. The sample tests can effectively reduce the risk of bulk procurement, especially suitable for project-based orders.
Q6. Can you support project orders?
Yes. We can support project-based batch purchasing and long-term supply requirements, including specification confirmation, clamping range recommendations, material matching suggestions, sample testing, and batch consistency supply. For structural connection applications, we can also provide more suitable specification solutions based on the customer’s operating conditions to enhance assembly stability and delivery efficiency.
