U-shape nails, also commonly referred to as U-nails or fencing staples, are specialized types of nails designed with a U-shaped design. They are mainly used to fasten wire fencing to wooden posts or for attaching wire mesh to wooden frames.
Design and Structure
Here are the key design features of U-shape nails:
- U-Shaped Body: The most distinguishing feature of these nails is their U-shaped design, which looks like a staple. This shape helps secure wires or mesh onto wooden surfaces effectively.
- Sharp Points: These nails have two sharp points designed to penetrate the wood easily.
- Material: Like most nails, U-nails are commonly made from galvanized steel to resist rust and corrosion. The galvanized coating protects the nails when used outdoors and exposed to weather elements.
Uses and Applications
- Securing Fencing: The primary use of U-nails is to secure wire fencing to wooden fence posts. They’re used to fasten various types of wire fencing, including livestock fencing, barbed wire, welded wire, and chicken wire.
- Attaching Wire Mesh: They’re also used for attaching wire mesh to wooden frames in applications such as garden fencing, chicken coops, and rabbit hutches.
- Securing Vineyard Wires: In vineyards, U-nails are often used to secure the wires that guide the growth of the vines.
- Holding Cables and Wires: In some situations, they can be used to hold cables and wires in place against wooden surfaces.
When using U-nails, it’s important to ensure that they’re hammered in securely and that the wire or mesh is held firmly but not overly tight. The wire should be able to move slightly to accommodate tension changes due to temperature fluctuations or animal pressure. If the wire is held too tightly, it could break or pull the staple out of the wood.
