FAQs About Knurled Body Metric Rivet Nut
What is a knurled body metric rivet nut?
A knurled body metric rivet nut is a type of blind rivet nut with external knurling (serrated surface) on its cylindrical body. The knurling enhances grip within the base material, preventing rotation after installation. It provides internal metric threads in thin or soft materials where tapping is not possible.
What are the advantages of knurled body rivet nuts?
a. Excellent Anti-Rotation Performance
The knurled outer surface embeds firmly into the base material during installation, effectively preventing the nut from spinning under torque or vibration. This is especially useful for softer materials like plastics or aluminum sheets.
b. Suitable for Various Materials
Knurled body rivet nuts are compatible with metal sheets, plastics, and composite materials, offering enhanced mechanical grip between the nut and the host material.
c. Secure and Stable Installation
The knurled design increases friction during setting, resulting in a more reliable and durable clamping force—ideal for applications requiring structural strength.
d. Supports Blind Hole Installation
Can be installed from one side of the workpiece without access to the back, making it perfect for confined or enclosed assembly environments.
e. Reusable Internal Threads
Equipped with standard metric threads, these nuts allow repeated insertion and removal of screws or bolts—suitable for maintenance-intensive applications.
f. Available in Multiple Head Styles and Sizes
Options include flat head, small head, countersunk head, and sizes ranging from M3 to M12, making them versatile across various industrial and commercial uses.
Are rivet nuts reusable?
The internal threads are reusable, meaning screws or bolts can be installed and removed multiple times. However, the rivet nut itself is generally a one-time installation; once set, it cannot be reused if removed from the base material.
What tools are required for installation?
a. Hand Rivet Nut Tool
Ideal for small batches or light-duty applications. Easy to operate and suitable for smaller sizes like M3–M6. Commonly used for repairs or DIY tasks.
b. Pneumatic/Hydraulic Rivet Nut Tool
Suitable for medium to large-scale production environments. Greatly improves installation efficiency and handles a wide range of sizes, especially larger ones like M8 and above.
c. Electric Rivet Nut Gun
Combines the benefits of manual and pneumatic tools. Well-suited for medium-frequency installations with good portability, making it ideal for on-site or mobile work.
d. Hole Punch or Drill
Used to create pre-drilled holes in the workpiece. The hole size must match the outer diameter of the chosen rivet nut (refer to technical datasheets for accuracy).
e. Caliper or Gauge
Ensures precise measurement of hole diameter and sheet thickness, helping confirm compatibility and preventing issues like spinning or improper fitting.
Are there different head styles available?
Yes. Knurled body metric rivet nuts are available in various head types such as flat head, reduced (small) head, and countersunk head to suit different assembly needs and surface flushness requirements.
What metric sizes are available?
Yes, there are several different head styles available for rivet nuts, each designed for specific applications and aesthetic or structural requirements. Here are the main types with detailed descriptions:
| Head Style | Key Features | Typical Applications |
| Flat Head | – Most common style – Large bearing surface – Good pull-out resistance | General use where the head sits on the surface |
| Countersunk Head | – Flush finish after installation – Smooth outer appearance | Automotive panels, electronics enclosures |
| Reduced (Small) Head | – Smaller flange diameter – Fits in tight or countersunk holes – Minimal protrusion | Limited space applications, aesthetic-focused designs |
| Large Flange Head | – Extra-wide bearing surface – Prevents pull-through in soft/thin materials | Plastics, composites, soft metals |
| Sealed (Closed-End) | – Bottom sealed – Prevents ingress of moisture/dust/debris | Outdoor, marine, electrical/electronic environments needing protection |
Can Knurled Rivet Nuts be used in high-vibration environments?
Yes, especially when combined with locking features such as thread-locking adhesives or paired with lock bolts. The knurled body resists spinning under vibration, making them suitable for automotive, machinery, and heavy-duty applications.
