All about lamb nuts

Nut-lamb – a fairly kind of fastening element, intended for mounting anything without additional devices and mechanisms, that is, with the help of only hands. This methiz received its name for the presence of “ears”, in which similarity with lamb horns. The rotation of the ears of the hand allows you to delay or, on the contrary, weaken the mount. The first nut-lambs at the beginning of the 20th century patented in Germany, which is why fasteners with rounded ears are called “German”. Soon a more technological modified version of the lamb of bent steel was patented in the US. Externally, it is easy to distinguish between square ears – this option was the name “American”.

Peculiarities

Both specified variants of hack-bara masks have now equally widespread use. But On this evolution of such a manual fastener stopped: new modifications appear, but now from other materials.

The main technical feature of the lamb nut is her self-sufficiency. Of course, it is impossible to use it without a bolt or stud, but even these hardware are selected so as not to use the key or screwdriver to hold them. For example, the hairpin can be welded or have a loop instead of the head, which it is moving towards the subject or part. Bolt either should not have a turnkey head or screwdriver. For example, the bolts used in the installation of wooden products can have a rounded head and special stops that, crashed into wood, prevent turning when tightening fasteners.

Hut-lamb combines and fastening hardware, and tool for its installation. The need for such a fastener arises in cases where it is necessary to quickly tighten or release the fastener of the removable part, which is not an element of the supporting structures. The selection of a key or screwdriver would have undoubtedly much time. At the same time, for functional consolidation, the effort of one hand without additional devices.

Dimensions

As GOST 3032-76 indicates, lamb nuts are distinguished by material manufacturing material and sizes. The main parameter on which all the rest depends is the diameter of the threaded hole. It corresponds to the standard sizes of bolts and nuts adopted in the modern industry, and labeling.

Minimum standard size m3. This means that the diameter of the bolt thread, to which you can turn such a nut, is 3 mm. A number of subsequent sizes of nut-barus looks like this: M4, M5, M6, M8, M10, M12, M14, M16, M18, M20, M24.

It is quite expected that the external sizes of nuts will increase in the same order. Most German-type nuts have holes in the ears. The purpose of the holes is not only to ease hotes: some masters use them for fixing the methization in a certain position using wire. But more often a cable or a kapron thread is tied to avoid the loss of methization.

In terms of thread, the lamb nuts are divided into products with large and fine threads, the step of which is determined by the size of the metric. Only large threads have lambs of small sizes: m3, m4, m5, m6. M8 nuts and then produced with both thread options. This fact should be considered when buying fasteners. If there is no experience in determining the size of the thread, the hairpin or bolt, to which the nut is supposed to be coated, can be suitable as a sample.

Closed-type lamb nuts that have a limit on the length of the stud, to which they have to be checked, are on sale much less. The dimensions of such hardware begin with M6, not less. Thread Steps We are usually no – the standard large thread is cut on.

Materials

Machine lambs made from various materials. Traditional is metal fasteners.

Due to small static and dynamic efforts acting on compounds with such nuts during operation, carbon steel can be used for their manufacture. These alloys are relatively durable, the cost is small, but there is a minus – they are subject to corrosion. In addition, not always such products satisfy the aesthetic requirements. Often, trying to slow down the corrosion destruction, they are applied with coatings impregnated with oils. For this reason, steel galvanized products are more common, not only successfully opposing corrosion processes, but also having a rather presentable appearance. In addition to zinc, other non-ferrous metals can be applied to coating steel dampers: copper, nickel, tin, silver and their alloys.

The most durable are stainless steel hardware, however, combining strength and aesthetics, they have a high cost. But since such removable fasteners are never used massively, so the use of stainless steel is quite justified.

The unique properties of organic polymers caused their use for the manufacture of fasteners with special requirements, for example, with increased moisture resistance. Contemporary fastener for the arrangement of bathrooms does not require increased strength, but the water resistance is obligatory. Therefore, it is not necessary to do without plastic nuts, which when installing do not require great effort, tightening with one hand.

Wide use of solid plastic lambs with steel core. These products fix various kinds of equipment and appliances. They are relevant where it is often turned away and fascinated fasteners, but the effort is limited by the dynamic properties of materials.

Application

As already mentioned, you can meet lamb nuts everywhere where great efforts are required, but often you have to mount and dismantle light designs.

So, Steel products are used to install fuel filters on some engines. This structural element is often changing.

In addition, they can be seen on the lids of hermetic tank thermos. The covers have to open and close several times per day, and damage the sealing gasket that provides tightness, an excessive tightening of nuts is unacceptable.

This also establishes the use of such products for fixing covers of hatches, hermetic doors or portholes.

In some cases, a closed fastener is used (When the ears of the nuts are connected in the form of a metal loop). Such hardware have a higher decorative component, so they can be applied to fix some household appliances.

Galvanized and stainless lamb can be seen in collapsible wooden structures. For example, sketches or easels that are attributes of artists, have a range of adjustable and folding parts. They are impossible to imagine without shiny hack-bars.

Parashka nuts in the designs of photochative, stage lighting and sound amplifiers are widely used. Mounting and adjusting such equipment is required very often, and we would be very uncomfortable with you for this purpose and screwdriver.

Large nuts for manual adjustment, which gained their development based on barashkov, can be found in the design of modern office chairs.

Plastic lamb nuts with steel closed type cores are used for the installation of some measuring electrical appliances and radio equipment. Here they allow you to reliably isolate fastening elements, preventing the possibility of short circuit.

As used fasteners of soft plastic when installing water and other plumbing equipment, already mentioned. But it should be clarified that with such a material it is impossible to use any tool, since the effort created when tightening with the hand, in this case it is quite enough.
