6.4 mm (1/4”) Blind Rivets Overview
6.4 mm pop rivets (also known as 1/4″ blind rivets) are large-diameter, single-side installation fasteners consisting of a rivet body and a mandrel. Installation is completed from one side of the workpiece using a riveting tool, forming a permanent mechanical locking structure. This specification falls within the heavy-duty fastening category, offering greater shear area and higher load-bearing capacity compared to smaller diameter rivets.
It is primarily used for thick plate connections, structural component assembly, and heavy industrial applications in high-vibration environments. Examples include automotive body manufacturing, steel structure joining, and heavy equipment mounting. It effectively enhances connection stability while reducing the risk of loosening due to excessive loads or prolonged vibration. This specification is commonly employed in structural-grade fastening solutions.

HOW TO CHOOSE
Blind Rivet Size Comparison
| Comparison Item | 4.8 mm Rivet | 6.0 mm Rivet | 6.4 mm (1/4”) Rivet |
|---|---|---|---|
| Shear Area | Smaller | Medium | Largest |
| Load Capacity | Suitable for general assembly | Suitable for medium to high load connections | Suitable for heavy-duty and structural applications |
| Typical Applications | Light sheet metal, general industrial use | Medium-thickness materials, equipment assembly | Steel structures, truck body manufacturing, heavy equipment |
| Structural Suitability | Generally not used for structural applications | Suitable for certain structural scenarios | Suitable for structural-grade and high-vibration environments |
Increased diameter means a larger shear cross-sectional area, enabling higher lateral load capacity under identical material conditions.
The 4.8 mm size is better suited for lightweight assembly scenarios; the 6.0 mm is suitable for medium load requirements; while the 6.4 mm (1/4″) size, with its larger cross-section and higher load-bearing capacity, is more appropriate for heavy-duty or structural-grade applications.
HOW TO CHOOSE
In the 6.4 mm (1/4″) specification, the adoption of a Structural Type design directly impacts connection strength and long-term stability. For heavy-duty or critical structural applications, Structural Type blind rivets typically offer greater advantages than standard types.
Mechanical Locking System
Structural blind rivets incorporate a mechanical locking mechanism that maintains a secure lock even after the mandrel breaks, preventing mandrel loosening or vibration-induced displacement. Compared to standard open-end blind rivets, their internal locking structure delivers more reliable joint integrity, making them particularly suitable for structural-grade applications.
Vibration Resistance
In high-vibration environments (e.g., vehicle operation or machinery running), structural blind rivets significantly reduce loosening risks due to their locking core design. In practice, structural products typically demonstrate superior connection stability under dynamic loads compared to standard types.
Higher Tensile Performance
Due to reinforced locking mechanisms, structural 6.4 mm blind rivets generally exhibit superior tensile performance compared to standard types. Under identical diameter and material conditions, tensile capacity increases by approximately 20–30% (specific values depend on material and structural design).
Dynamic Load Stability
Under cyclic loading or impact conditions, the structural design more effectively disperses stress concentrations, reducing fatigue risks in the joint. For structural nodes involving safety or long-term load-bearing, structural blind rivets offer superior engineering suitability.

6.4 mm (1/4”) Blind Rivets Technical FAQs
Q1: What hole size for 1/4 rivets?
For 6.4 mm (1/4″) blind rivets, the recommended drill hole size is typically 6.5–6.6 mm. The exact size should be determined based on material thickness, tolerance requirements, and installation standards. An appropriate hole diameter helps achieve stable clamping force.
Q2: How strong are 6.4 mm rivets?
Due to their larger diameter, 6.4 mm rivets exhibit higher tensile and shear strength under identical material conditions. Their tensile and shear performance typically surpasses that of 4.8 mm rivets, making them suitable for medium-to-high load and structural-grade applications. Specific strength data should be referenced from actual test reports.
Q3: What is the difference between structural and standard blind rivets?
Structural blind rivets feature a mechanical locking core design that maintains a locked state even after the mandrel breaks, enhancing vibration resistance and tensile strength. Standard rivets are generally suitable for routine assembly, while structural rivets are better suited for high-vibration or critical load-bearing areas. In heavy-duty or safety-critical applications, structural rivets offer greater engineering suitability.
Q4: Can 6.4 mm rivets replace bolts?
In certain medium-load structural connections, 6.4 mm blind rivets can serve as an alternative to bolts, particularly in installations where dual-side access is unavailable. However, for applications requiring extremely high strength or removable connections, engineering evaluation based on design loads and safety factors remains essential.
Q5: Do you support OEM and bulk supply for open end blind pop rivets?
