Grooved Pop Rivets
Grooved pop rivets a special type of rivet with a grooved structure, usually used to join materials with low strength or brittle materials. For example, wood, plastic, composite materials, etc.
When grooved rivets are properly installed, the grooves in the rivet’s subject bite into the wood or plastic, providing additional mechanical grip and holding power.

What Are Grooved Pop Rivets?
Grooved pop rivets are blind rivets featuring longitudinal or circumferential grooves on the outer surface of the rivet body. These grooves enhance mechanical interlocking between the rivet body and hole walls during the riveting process, thereby improving resistance to rotation and pull-out.
The primary purpose of the grooved structure is not to increase ultimate tensile or shear strength, but to prevent rivet rotation or loosening after installation. Standard pop rivets are more prone to rotation in smooth hole walls, soft materials, or vibrating environments, whereas the grooved design significantly mitigates this issue.
Engineering tests indicate that under identical installation conditions, grooved pop rivets typically exhibit 20–40% greater resistance to rotation than smooth rivets (specific values depend on material and groove geometry).
Suitable Materials and Applications
Thin Sheet Metal Joining (Aluminum or Thin Steel Sheets)
In sheets ≤2.0 mm thick, limited friction on hole walls allows smooth rivet bodies to rotate easily. Grooved Pop Rivets enhance anti-rotation stability by engaging with hole walls through their grooves, making them suitable for long-term use in thin sheets.
Soft Metals or Composite Materials
Hole walls in soft metals and composites are prone to compression wear. The grooved structure increases radial contact area by approximately 15–30%, reducing the likelihood of joint loosening during service.
Structures Subject to Vibration or Light Dynamic Loads
Under mild vibration conditions, the friction of smooth pop rivets diminishes over time. Testing indicates that Grooved Pop Rivets typically exhibit 20–40% higher resistance to rotation, making them more suitable for applications requiring long-term stability.
Loose Hole-Rivet Fit Assembly Conditions
When hole tolerances are excessive, the initial stability of smooth rivets significantly decreases. The radial clamping force generated by the groove partially compensates for hole diameter deviations, improving assembly tolerance.
Key Differences from Standard Pop Rivets
- Standard Pop Rivets: Smooth rivet body relies on the flared tail for clamping force
- Grooved Pop Rivets: Rivet body features grooves, providing additional radial gripping force
Grooved structures are preferable when applications require anti-rotation stability. For scenarios prioritizing quick installation and cost efficiency, standard pop rivets are typically sufficient.
What are the Common Materials Used to Manufacture Grooved Blind Rivets?
Grooved Blind Rivets are typically made from aluminum, steel, stainless steel, and copper. Aluminum rivets are commonly used in lightweight applications, while steel and stainless steel rivets are suitable for applications that require more strength.
Rivmate offers grooved rivets in Aluminum/Steel combinations. this is the most common material combination. Of course, if your project has special needs, you can contact our engineers!
What Are the Main Advantages of Grooved Pop Rivets?
1️⃣ Enhanced Anti-Rotation Stability
Grooved Pop Rivets achieve superior anti-rotation performance through mechanical interlocking between the rivet body’s grooves and hole walls. Engineering tests demonstrate that under identical installation conditions, their anti-rotation capability typically exceeds smooth-body pop rivets by approximately 20–40%, making them particularly suitable for thin sheets and vibrating environments.
2️⃣ Enhanced Reliability in Thin Sheets and Soft Materials
In thin sheet metals (≤2.0 mm), aluminum alloys, and composite materials, standard pop rivets often loosen due to insufficient hole wall friction. The grooved structure increases radial contact area by approximately 15–30%, reducing the risk of material tearing or joint failure.
3️⃣ Greater tolerance for hole diameter deviations
Oversized holes are common in mass production. Grooved Pop Rivets partially compensate for hole-to-rivet gaps through radial clamping force generated by the grooves, maintaining stable connections even with loose holes and reducing assembly defect rates.
4️⃣ Enhanced Stability Under Vibration
In environments with minor dynamic loads or prolonged vibration, friction from smooth rivet bodies diminishes over time. Grooved Pop Rivets rely on mechanical interlocking rather than friction alone, significantly reducing the likelihood of loosening during extended use.
5️⃣ Eliminates Need for Additional Anti-Loosening Measures
In most applications, Grooved Pop Rivets can directly replace solutions requiring washers, adhesives, or other anti-loosening designs, achieving higher connection stability without adding installation steps.
6️⃣ Higher Installation Consistency, Suitable for Mass Production
Grooved Pop Rivets exhibit low sensitivity to hole wall conditions and operator variations. The grooved structure accommodates installation deviations within a certain range, ensuring more stable anti-rotation performance during mass installation.
Do I Need Special Tools to Install Grooved Pop Rivets?
Grooved Pop Rivets require no special installation tools.
Their installation method is identical to standard pop rivets. The grooved structure is located on the outer surface of the rivet body, which does not affect the core pin break-off mechanism or the operation principle of the riveting gun. Therefore, no specialized equipment or additional tooling is required.
Basic installation can be completed with a manual rivet gun.
For small batches or field operations, manual rivet guns can reliably install Grooved Pop Rivets. During installation, the grooves mechanically interlock with the hole walls, providing additional anti-rotation stability. This process does not depend on tooling modifications.
Pneumatic or electric riveting guns offer superior consistency control.
For medium-to-large volume assembly, pneumatic or electric tools deliver more stable pulling force, ensuring uniform groove engagement with the hole walls. Production experience demonstrates that consistent force significantly reduces anti-rotation performance variations caused by operator inconsistencies.
Are Grooved Pop Rivets Removable?
Grooved Pop Rivets are not removable fasteners.
Like standard pop rivets, Grooved Pop Rivets achieve a permanent connection through plastic deformation upon installation and are not designed for repeated removal.
Removal is only possible through destructive means.
To remove Grooved Pop Rivets, the common methods involve drilling off the rivet head or drilling through the rivet body. This process destroys the rivet body and may enlarge the hole diameter in thin sheets or soft materials.
The grooved structure increases removal difficulty.
Due to mechanical interlocking between the grooves and hole walls, Grooved Pop Rivets exhibit higher resistance to rotation during removal compared to smooth rivets. They are less likely to rotate with the drill bit during drilling but cause greater wear on the hole walls.

Why Import Grooved Pop Rivets from China?
Many manufacturers or distributors in the world who use blind rivets choose to import blind rivets from China. So do you know why they import blind rivets from China instead of buying them locally? There are mainly several reasons:
- Price advantage
- Advanced manufacturing technology
- Strong customization capability
- Rich customer experience
China’s manufacturing industry has a clear cost advantage, especially in the case of low raw material and labor costs. Imported grooved blind rivets can significantly reduce purchasing costs and improve profitability.
