What does the number on a staple series actually mean?
71. 80. 90. 140…
It’s easy to assume the numbers tell you the size. They don’t.
Staple series are reference codes, so when you’re choosing a staple, you still need to consider the crown width, wire gauge, leg length, application and whether it’s compatible with your tool.
That’s also why two series used for similar jobs aren’t necessarily interchangeable.
We’ve put together a straightforward guide explaining the common staple series and what you actually need to look for.
