There are generally three types of staple wire, and they all have different characteristics, strengths, and use cases. The three types of staple wire:

This wire is slim and discrete, and because of this, the staple will leave a skinny impact after penetrating the material. For this reason, fine wire staples are ideal to use on fabrics, upholstery, and picture framing.

If you want a stable staple with higher performance compared with the fine wire, this is the wire you should choose. It can handle more robust material because the wire gives it more strength and stability. Excellent to use in pallet boxes, lighter wood manufacturing, and heavy fabrics.

The robust and robust choice in the staple wire assortment. If you have an application that demands high holding power combined with demanding and rigid material, this wire is the choice. Perfect to use for wood framing, furniture, framing, carton to wood pallets, and fastening heavy wood to wood.
When comparing different staples, they often have a gauge classification number. This number comes from American Wire Gauge, AWG. AWG is a standardized wire gauge system, and from this, we can conclude the thickness of the staple wire. As a rule of thumb, the higher the gauge number, the thinner the wire. So a gauge number of 20 indicates a thicker, heavier wire than a 22-gauge.
| Gauge | 22 | 21 | 20 | 19 | 18 | 16 | 14 | 12 | 10 |
|---|---|---|---|---|---|---|---|---|---|
| Fine wire | x | x | x | ||||||
| Medium wire | x | x | |||||||

The crown of the staple is vital because it is the actual part of the staple that keeps the material together. And depending on your material, there are different crowns available.

Is used for discrete carton closing, woodwork, and fine carpentry.

Is great to use on applications like home wrapping, cedar shingles, and woodwork.

Mainly used for carton closing. It has a high holding power due to having a wide piece of metal over the cardboard, holding it together.
There are many different staple leg lengths down to the precise mm for almost every staple. So how do you know what leg length to choose for your application? Here is a simple rule to remember:


Multiply your material thickness by three. For example, if you are stapling 5mm thick wood, you need a 15mm leg length.

When stapling thin materials like plastic foil or fabrics to wood, the staple should be 4mm longer than the thickness of the material.

When stapling through hardwood, the staple should be twice as long as the thickness of the wood.
Depending on your application environment, you have to choose a staple material that matches that environment. For example, if your finished application stays indoor with no humidity, it requires one specific staple material, and if it stays outdoor close to water, it needs another kind of staple material.

The most commonly used staple on the market. These staples are made of steel with zinc plating that helps them resist general corrosion and therefore keeps the rust away. If they are used indoor, they will last forever with no rust whatsoever, but if you use them in an outdoor and damp environment, the staple will rust to some extent.

Josef Kihlberg produce carton closing staples with a copper finish. This gives them an exclusive aesthetic appeal compared to the regular galvanized type and offers the same level of rust protection. In addition to this, the copper coating improves the staple operation through the stapling tool as it works as a mild lubricant to keep the staple machinery going perfectly.

Are you working in a sensitive environment like a sawmill and want to avoid causing a spark? Or perhaps using staples around a magnetic area as an MRI field? Then using an aluminum staple is the choice for you. Aluminum staples are also very smooth to cut into if there is a need to remove them.

Stainless steel staples are perfect to use in an application used outdoors and or exposed to humid environments. The typical grades for stainless steel staples are grade 304 and 316. 304 is the most common one due to its outstanding rust resilience. We strongly recommend making a 304 choice if your application spends continuous time outdoor. A stainless-steel 316 staple gives the ultimate rust protection. It will not get affected by harsh environments like saltwater. Use 316 as your choice for applications located at sea or close to the coastline.

Staple legs come with different types of points. It is the end of the staple that pierces the material when used.

This is the most common type and is engineered to penetrate the material in the best ways possible. It goes straight through the material and forces the two legs towards each other.
Once the staple has penetrated the application material, you want the staple legs to bend to stay securely fastened. The terminology for this bend is clinching. And depending on your application, there are different ways to clinch.
