Comparison DeWALT DWHT0-TR510 vs Stanley FatMax FMHT6-70868

The main structural element of the construction stapler. The spring first compresses, accumulating mechanical energy, and then decompresses, releasing it to clog the fastener. According to the type of springs are divided into two subcategories:

— Vitaya. The impact mechanism with a twisted (torsion) spring is cocked and then released when the lever is pressed. The force with which the bracket will be clogged is regulated using a special screw, if it is provided for in the design. The working resource of a twisted spring averages 10-12K strokes, after which the recoil becomes stronger and it is no longer so comfortable to work with the tool.

— Plate. In staplers with a leaf spring, a flat spring located horizontally is responsible for the tension of the striker. Usually, this type of springs is used in professional tools — they have a long service life (about 55 – 60K strokes), which allows the use of construction staplers for large-scale work.

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 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 movements" du...ring 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 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 thickness of nails (see "Type of fastener") that the stapler can work with.

A nail that is too thin is just as undesirable for a tool as one that is too thick: already in the store, such parts can hang out, and there is no question of correct “shooting” at all. Therefore, this limitation should definitely be taken into account when choosing, especially if you plan to work with nails of small thickness. The most "thin" modern staplers have a minimum limit of about 1 mm, and in professional models it can exceed 2.5 mm and even 3 mm.

The largest thickness of nails (see "Type of fastener") that the stapler can work with.

Thick nails require not only the appropriate size of the magazine and feeder, but also significant effort is required to drive them. Therefore, the larger the maximum allowable nail diameter, the more powerful, heavier and more expensive the tool, usually. Professional pneumatic nailers can be compatible with fasteners of 3.5 mm or more, but for entry-level tools, a thickness of 1.2 — 1.5 mm is often more than enough.
