V-Nails: The Ultimate Picture Framing Nail
If you’re wondering what nails to use for picture frames, the unsung hero behind a professional frame is the V-nail. These small yet powerful fasteners securely join frame corners, creating seamless, virtually invisible joints.
V-nails are V-shaped fasteners that are driven into the back of two frame moulding pieces at the joint, pulling them tightly together. This technique ensures structural strength while supporting the aesthetic integrity of the frame.
However, not all V-nails are created equal, and matching the right nail to the job can make all the difference.
V-Nails Tailored for Every Material
We offer a full range of Genuine AMP & Universal V-nails to accommodate every project. Each type of V-nail is specifically engineered to work with different materials.
Soft Wood Power-Twist V-Nails (SPT) (SW)
Description: Perfect for less dense materials. These V-nails are sharpened on the inside edge only. They feature an angled grind, or tapered edge, that cuts cleanly through softer woods without splitting.
Best Used With: Soft woods such as poplar, pine, and cedar, as well as soft plastic/polystyrene mouldings.
Available Sizes: 7mm, 10mm, 12mm, and 15mm
Medium/Hard Wood Power-Twist V-Nails (HPT) (MW/HW)
Description: Designed for denser materials. These v-nails have both edges sharpened and a blunter grind (angle). They counteract the greater resistance found in harder woods and more rigid plastics.
Best Used With: Denser woods such as oak, ash, hickory, cherry, maple, and walnut. Also works well with harder plastic/polystyrene mouldings.
Available Sizes: 5mm, 7mm, 10mm, 12mm, and 15mm
Hard Fiberboard Power-Twist V-Nails (HDF) (MDF)
Description: Specifically engineered for MDF and other fiberboard materials. These nails are slightly thicker, enabling them to drive into the densely packed fibers without compromising the board’s structure.
Best Used With: MDF and fiberboard materials.
Available Sizes: 7mm, 10mm, 12mm, and 15mm
How to Choose the Right V-Nail
Choosing the proper V-nail involves several key considerations:
- Frame Material: Softwood, hardwood, MDF, or polystyrene? Select the correct type of V-nail to match the material’s density.
- Frame Thickness: The depth of the V-nail must align with the thickness of the moulding without over-penetrating.
- Spacing and Quantity:Use multiple V-nails across the width of the frame for added strength. Avoid positioning nails too close to either edge to prevent splitting or visible deformation.
Pro V-Nail Tips
- Always match the nail not just to the frame’s material but also to the depth of the moulding. This ensures maximum holding power without piercing through the face.
- For thicker frames, stacking V-nails (placing one above another) can significantly enhance corner durability without compromising the appearance.
