T50 staples are probably the most popular staples in the US and possibly even worldwide. They are a type of fastener designed for light- to heavy-duty applications. They commonly unite two or more pieces of material, such as wood and plastic.
T50 staples are the perfect choice for jobs requiring quick tacking or household projects. They provide reliable fastening with a secure fit, reducing the chance of slips or jams. They come in various lengths for different materials, making them ideal for creating custom pieces from wood, plastic, and more. These staples are ideal for multiple uses. In this blog, we will cover the uses of T50 staples, their applications, and tips for selecting the right ones for your project.
What Does T50 Mean in Staples?
The term "T50" in staples refers to a widely used heavy-duty staple type designed for various fastening applications. These staples provide strong, secure attachment for materials like wood, plastic, and fabric in professional and DIY projects. Arrow Fastener originally manufactured T50 staples, setting a standard for quality and compatibility with multiple staple guns.
Their flat crown design ensures a firm grip, reducing movement and increasing durability. Available in various sizes, T50 staples are designed to adapt easily to different materials and applications.
What Are T50 Staples Used For?
The T50 staple is renowned as the staple standard, holding its place as one of the best-selling staple heavy-duty fasteners worldwide. Designed to work with the Arrow T50 staple gun and other compatible staplers, these staples deliver exceptional holding power.
As previously mentioned, the world's best-selling heavy-duty staple platform is the T50 staples originally manufactured by Arrow. With exceptional holding power, these staples are perfect for a wide range of heavy-duty stapling applications such as:
- Housewraps
- Roofing underlayments
- Upholstering fine furniture and window treatments
Due to their thicker gauge, these staples are not suitable for office use but excel in construction and remodeling projects. These staples possess enough strength to penetrate even light wood trim, given that the stapler itself is sturdy enough.
Staple Length For Insulation
Choosing the right staple length for insulation is crucial for achieving a secure hold without damaging the material. Insulation requires staples that are long enough to penetrate the facing and grip the wood substrate, but not so long that they pierce too deeply.
For most residential insulation projects, staples in the 3/8" to 1/2" range provide a reliable hold. These lengths ensure the insulation stays in place while reducing the risk of tearing or compressing the material. When working with foil-faced or kraft-faced insulation, select staples that pierce cleanly without wrinkling the surface.
For added protection in damp or humid areas, such as basements or attics, using corrosion-resistant staples helps maintain long-term durability by preventing rust and deterioration.
Are T50 and 140 Staples the Same?
T50 and 140 staples are essentially the same, with T50 being a common brand name and 140 being a series designation for the same type of heavy-duty, flat wire staple. T50 staples feature a proprietary design, ensuring a secure fit with Arrow and other compatible staplers.
Always check your stapler’s specifications before selecting the correct staple type for your project’s needs.
What Size Are T50 Staples?
A T50 staple is characterized by its flat top, also known as the "crown," which measures approximately 3/8".
PLEASE NOTE **The labeling of the crown size is subject to interpretation by the manufacturer. Some manufacturers label as 7/16" crown, while others label as 3/8" crown. The T50 / A11 staple is a proprietary crown size. These staples are manufactured according to T50 and A11 (R11) specifications and are compatible with T50 and similar staplers.**
Common T50 staple lengths include:
- 6mm (1/4″)
- 8mm (5/16″)
- 10mm (3/8″)
- 12mm (1/2")
- 13mm (17/32″)
- 14mm (9/16″)
Manufacturers typically produce T50 staples from steel, often with a galvanized T50 staples coating or a rust-resistant zinc finish to improve performance. For projects requiring maximum durability, such as roofing or outdoor applications, contractors often prefer stainless steel T50 staples due to their unmatched corrosion resistance.
What Gauge Are T50 Staples?
T50 staples typically have a 20-gauge thickness. This makes them strong enough for heavy-duty applications like upholstery, insulation, carpeting, and even roofing underlayment staples. Their robust construction prevents bending during installation while ensuring excellent holding power.
Thanks to their versatility, T50 staples are compatible with many staple guns, making them a go-to fastener across different trades. Always verify your tool's compatibility before selecting the correct staple gauge for your project.
How to Load a Staple Gun T50?
Loading a T50 staple gun is simple:
- Squeeze and pull the pusher rod at the back of the tool.
- Insert the staples into the magazine rail with their legs facing downward.
- Slide the pusher rod back until it clicks into place, securing the staples.
- Test on scrap material to ensure smooth operation.
Always follow safety guidelines to avoid injury while loading and using a staple gun.
