Standard sizes of fasteners for which the tool is designed. This information is necessary for the correct selection of consumables: each standard dimensions corresponds to certain dimensions of parts, and sometimes also design features. There are a great many standards describing standard sizes; they differ not only in the type of fastener, but also in the geography of application and even by specific manufacturers. Detailed data on various standard sizes can be found in special sources; here we will provide general points on some of the most popular options.

First of all, it is worth saying that the standard dimensions describes only two parameters - thickness and width (for nails - size and width of the head). The length can be different: for example, for the popular staple dimensions 53, the length range can be from 4 to 14 mm, and for 140 - from 6 to 14 mm. At the same time, tools for a certain standard dimensions are not necessarily compatible with all length options. So when assessing compatibility with consumables, you should pay attention not only to this point, but also to the restrictions on the minimum and maximum length of fasteners.

This is what the list of the most popular sizes for rectangular brackets looks like:

- 55. One of the smallest sizes used in modern staplers is 6 mm wide and 1.1 mm thick.
- 90. Another relatively small standard dimensions, it has even a slightly smaller width - 5.8 mm - and a thickness in the...range of 1 - 1.27 mm.
— 57. Staples 10.6 mm wide and 1.2 mm thick.
- 59. The “thin” analogue of dimensions 57, with the same width, provides a thickness of only 0.75 mm.
— 140. Quite rigid staples with a width of 10.6 mm and a thickness of 1.24 mm.
- 114. A slightly enhanced variation of dimensions 57, with increased width and thickness - 10.8 mm and 1.4 - 1.6 mm, respectively.
- 53/53F. Quite wide (11.3 mm) staples, available in both 0.75 mm (53) and 1.25 mm (53F) thicknesses.
— 72. In fact, it’s an analogue of the 53 described above: staples 11.3 mm wide and 0.7 mm thick.
- 54/58. Wide staples 12.8 - 12.9 mm, also available in two thicknesses - 0.75 mm in version 58, 1.25 mm in version 54.

Of the semicircular staples used mainly for fastening cables, the most popular options are:

- S. Relatively small staples with a width of 6.2 mm and a thickness of 1.25.
- L. Larger dimensions - 7.7 mm wide with the same 1.25 mm thickness.

In nails for driving tools, the thickness is indicated by the size, and the width by the largest dimensions of the head. The most popular sizes these days are:

— J. Small fastening nails only 1.2 mm thick with a head width of 2 mm.
— N. Diameter 1.65 mm, cap width 2.8 mm.
- DA. The so-called finishing (finishing) nails are quite large in dimensions: size 1.8 mm, head width 3.5 mm. The head has a characteristic D-shape and, as befits finishing nails, when hammered, it is almost completely recessed into the material.

Regarding pins/studs, it is worth noting that such fasteners are actually nails without heads. Therefore, the main dimensions of such parts is thickness (size), for the most common standard sizes it is as follows:

— 40. Thin pins/studs, only 0.64 mm thick.
— 41. Larger fastener, with a size of 1.2 mm.

Detailed information on choosing a standard dimensions for specific tasks can be found in special sources.

Staple models that the tool is compatible with.

Usually, quite specific options are indicated in this paragraph, so finding compatible consumables is not difficult. The specific dimensions of the fasteners should be specified according to the manufacturer's data — different brands use different markings.

The total power consumed by a mains-powered electric tool (see "Power Source"). It is considered the main criterion for assessing the overall capabilities of a particular model: more power leads to better performance. In addition, data on power consumption also allows you to estimate the load on the power grid or other power source; in some cases this is unnecessary.

The actuation method provided in the design of the nail/stapler.

- Contact. This option assumes that direct contact with the material being processed is necessary for operation. Usually, a movable working tip (“nose”) is used for this: until the tool is pressed against the material and the nose is not retracted to the stop, the mechanism will not work. This way of actuation has a positive effect on both efficiency and safety of work: tight contact ensures that the fastener will be hammered as reliably as possible, and the risk that the hammer will “shoot” with a staple or nail in the air is reduced to almost zero. However the need to press the tool tightly every time reduces the speed of work: although pressing takes a fraction of a second, however, on tens and even more hundreds of clogged fasteners, this moment becomes noticeable. On the other hand, many tools provide the ability to hold the trigger so that the stapler automatically fires each time the spout is pressed. But the unequivocal disadvantage of this option can be called the fact that the presence of a safety contact mechanism complicates and increases the cost of the tool.

- Non -contact. Mechanisms that work regardless of whether the tool is pressed against the material or not. Other things being equal, the non-contact method of operation is faster than the contact one, because. does not require additional "body movemen...ts" during work. And the tool itself is lighter and cheaper. On the other hand, non-contact triggering requires increased care from the user: if handled carelessly, the tool can trigger at a certain distance from the surface of the material (which impairs clogging efficiency), or even “shoot” in an undesirable direction, which is fraught with material damage and even serious injury .

A device that protects the tool from being triggered at the wrong time.

Most often in a modern tool there are manual fuses in the form of a button or switch. Such a device blocks the release button or opens the power circuit; thus, when the fuse is on, the tool will not work, no matter what the user does. This reduces the chance of fasteners "shooting" in the wrong direction and reduces the risk of personal injury and property damage.

The number of fasteners that fit in the stapler magazine.

Note that manufacturers tend to indicate the maximum number of parts in the characteristics — that is, the capacity for the thinnest fasteners allowed by the design of the tool. Accordingly, fewer larger parts will fit in the store; this must be taken into account when choosing. Nevertheless, this parameter makes it possible to evaluate the instrument and compare models similar in class to each other.

Large capacity, on the one hand, allows you to work longer without interruptions to recharge the stapler. On the other hand, volume magazines are usually very bulky and can weigh a lot on their own, not to mention the weight of the fasteners loaded in them. Also, if parts are charged one at a time, recharging can become quite a long and tedious affair. Therefore, it makes sense to specifically look for a tool for 100 parts or more(especially when it comes to thick fasteners) only if the ability to work for a long time without reloading is more important than the disadvantages described above.

The smallest staple width that the stapler can handle.

The width of the bracket is, roughly speaking, the distance between its legs. Different situations and types of work require different sizes of staples, sometimes quite small. At the same time, staples that are too small will hang out in the store and will not be able to properly fit under the drummer, which is why modern staplers have a minimum size limit. You should pay special attention to it if you plan to work with brackets of small width.

The largest width of staples (see Fastener Type) that the stapler can work with.

The width of the bracket is, roughly speaking, the distance between its legs. Different situations and types of work require different sizes of staples, and sometimes the width must be quite large. However, a staple that is too large simply will not fit into the store, not to mention the fact that the stapler can “shoot” it normally. Therefore, this limit cannot be exceeded, and if you plan to work with brackets, you should pay special attention to the maximum width when choosing.

The smallest length of staples (see Fastener Type) that the stapler can work with.

The length in this case means the length of the leg — in other words, the depth to which the staple clogged "to the stop" penetrates into the material. Small staples do not require much power to drive, but the tool may not be designed for fasteners that are too short due to other parameters — for example, the design of the magazine. Therefore, for many models, this limitation is quite relevant, and in powerful professional models, the minimum length can be quite large — more than 20 mm.
