Are you working on a framing project that requires v-nails, or are you curious about their purpose?
Explore our guide on using v-nails for crafting the perfect picture frame. Gain insights into choosing the right type of v-nails and discover the essential tools for a successful installation.
What Are V-Nails?
V-nails, also known as wedge nails, are specialized nails designed for securely binding corners, most commonly of picture frames. Made from high-quality steel, these nails are driven into the corner joints using specialized tools, creating a strong, tight-fitting bond.
What Type of V-Nail Do I Need?
They come in a variety of types and sizes to suit different frame materials and project needs.
- Hard Power Twist v-nails are recommended for harder wood varieties like Walnut, Cherry, Maple, and Ash, due to their superior strength and resilience.
- Soft Power Twist v-nails are ideal for softer woods such as Cedar, Poplar, and Banak, providing a strong yet flexible hold.
- Hard Fiberboard Twist v-nails are best used for medium to hard MDF materials.
These versatile nails are also compatible with other types of hard and soft plastics.
Available in sizes from 5mm to 15mm, you can easily match the right size to your frame’s thickness.

Tools That Make V-Nail Installation Easy
Using the right tools can make a big difference in both the ease and outcome of your framing project. Specialized joiners, called underpinners, provide powerful and seamless v-nail driving.
- Manual Underpinners: Perfect for beginners or those who work with V-nails occasionally. These make the process smooth and controlled.
- Pneumatic & Electric Underpinners: Ideal for high-volume or frequent framing, offering speed and precision for consistent results.
While you can insert V-nails by hand, it’s not recommended. It is difficult to do cleanly and risks damaging the frame material.

How to Use V-Nails for Picture Frames in 4 Simple Steps
Since v-nails are most commonly used in picture framing, here is how to install v-nails in a frame successfully.
- Apply Wood Glue: Add a thin layer of glue to the mitred edges of your frame and spread it evenly.
- Join the Corner: Press the glued ends of your frame together firmly to form the joint.
- Set Up the Frame: Position your frame in the underpinner.
- Drive the V-nails: Using the underpinner, drive the v-nails into the corner joint. Repeat this for all four corners of the frame.
NOTE: If the frame is wide, add another v-nail towards the center of the joined frame on each side, completing the frame with eight v-nails installed.
That’s it—you’ve just completed a professionally joined frame!
