The number of "shots" for which the impact mechanism of the construction stapler is designed. For models with a twisted spring, it averages 10 – 12K strokes, for instances with a leaf spring — 55 – 60K operations.
Min. nail length
The shortest length of nails (see Fastener Type) that the stapler can handle.
The shorter the fastener, with the same thickness, the less effort is required to drive it, but a nail that is too short simply cannot stand under impact normally. Therefore, for many instruments, this restriction is directly indicated. It is worth paying attention to it first of all if you plan to work with small short nails.
Max. nail length
The longest length of nails (see Fastener Type) that the stapler can handle.
With the same thickness, a longer nail requires not only the appropriate space in the magazine and feed mechanism, but also a higher impact energy — otherwise it simply will not work to hammer it “on the head”. This means that the maximum fastener length is directly related to the power and, accordingly, the overall level of the tool. Recall that a powerful professional tool has the appropriate dimensions and weight, moreover, it is often made pneumatic (for more details, see "Type"). Therefore, it makes sense to look for models that are compatible with long nails only if this is critical for the planned work.
Min. pin length
The shortest length of the attachment pin (see Attachment Type) that the stapler can handle.
Parts of small length are clogged relatively easily and do not require much effort, however, fasteners that are too short simply will not be captured by the tool and will “shoot” as expected. Therefore, modern staplers often have a limitation not only on the maximum, but also on the minimum length of the pin. This option is especially relevant if you plan to work with small details.
Max. pin length
The longest attachment pin (see Attachment Type) that the stapler can handle.
A long pin not only needs to fit in the magazine and the feed mechanism of the tool — it also requires significant effort to be applied, otherwise the part cannot be hammered to the desired depth. Accordingly, an increase in the permissible length of the pin (with the same thickness) requires an increase in the power of the tool, and this, in turn, affects the dimensions, weight and price. In fact, this means that the principle "the more — the better" does not work in this case — you should choose a stapler based on how much longer the length is really needed for the planned work.
