There is a fairly large assortment of fasteners. Each type is designed to work with certain materials in order to achieve high quality fixation. In addition, there is a universal fastener. The demanded square washer M3 is necessary for fixing metal products. In addition, a square product is used for other purposes.
The Importance of Quality Metal
The fastener in the twisted state is under constant tension. In order for it to withstand constant static and dynamic loads, it is necessary to initially use high-quality raw materials. An additional coating that protects the hardware from corrosion will be a great advantage in everyday use. It is worth adding to other important characteristics of fasteners:
- Strict compliance with accepted international standards.
- The strength declared by the manufacturer is true.
- Easy assembly and disassembly if necessary.
- Having a fairly large variety on sale.
- The absence of marriage in a batch of the same type of products.
Important: the better the raw material used by the manufacturer for the manufacture of fasteners, the longer it will serve as a retainer for a wide variety of parts. Even such a seemingly insignificant detail as a washer plays an important role in the reliability of fixation.
Diversity of washers assortment
Square shape with a hole in the middle, these are the only common characteristics of washers. In fact, slight differences in structure allow the fastener to be used with a variety of materials. Only in this case can you count on a reliable connection without damaging parts or materials to be joined. The most popular and sought after are:
- oblique square washer for channel;
- for timber structures with zinc protection;
- with an increased bevel angle for an I-beam;
- for assembly construction work without coating;
- the most expensive and valuable made of stainless steel.
The square shape and slight difference in thickness is needed to compensate for misalignment of the nut and bolt head. If such a washer is not used, the connection will not be tight enough, which is guaranteed to lead to an emergency in the future. For each work, it is necessary to correctly select the appropriate fasteners and hardware.
