Silicon Bronze Washer, Zinc Plated Steel Washers, Socket Head Cap Screw Lock Washer

When using screws, flat washers are used. There are many materials of flat washers, and the sizes are also different. The specifications of flat washers used by different nuts are also different. How to choose the materials of flat washers, where to use the flat washers of what materials, and how to process the flat washers? How to choose and purchase flat washers at ordinary times, and what are the key points of purchase, The following is an introduction to the material selection and processing technology of the flat washer.

Flat washers are usually thin pieces of various shapes used to reduce friction, prevent leakage, isolate, prevent loosening or spread pressure. Many materials and structures have such components, which are used to perform various similar functions. Due to the material and process limitations of threaded fasteners, the bearing surface of fasteners such as bolts is not large. Therefore, in order to reduce the compressive stress on the bearing surface and protect the surface of the connected parts, washers are used. In order to prevent the looseness of the connecting pair, the anti loose spring washer, multi tooth lock washer, round nut lock washer and saddle shaped, wave shaped and conical elastic washer are used.

Material selection and processing technology of plain washer

In threaded fasteners, because the bearing surface of bolts, screws and nuts cannot be made very large (limited by materials and processes), washers are used to reduce the compressive stress on the pressure bearing surface and protect the surface of the connected parts.

Flat washer material selection:

The flat washer shall be made of hot-rolled steel plate, hot-rolled and pickled steel plate or cold-rolled steel plate by stamping 'or by bar and tube cutting, rolling, forging and other processing methods. The specific processing method shall be determined by the manufacturer.

Plain washers without mechanical property requirements are generally made of angle materials, such as Q235A. When there are hardness requirements but they are not high, they can be calendered with thicker plates to achieve the required hardness. The spring washer and other anti loosening washers are generally made of 65mn70\or s50cm-s70cm, and shall undergo heat treatment (quenching + tempering)

Processing technology of flat washer:

There are two main processing technologies for flat washers, one is deburring treatment, the other is surface protection treatment;

Deburring treatment: the gasket shall be deburred and deburred by polishing, vibration or other methods.

Surface protection treatment: in the standard, the surface treatment of washer products is divided into coating (thick) and coating (thin). The author believes that it should also be applicable to other fastener products - Bolts (screws, studs) and nuts. Although it is not as specific as the standard in some other corresponding standards.

Warm reminder: if there are no other provisions for the washer without protective layer, the surface of the washer shall be ordinary, that is, there is no other coating (plating) except for the anti induced oil.

The above introduction is about the selection of flat washers and the processing technology of flat washers. Everyone has a certain understanding of how to select materials and how to make flat washers. In fact, when using nuts, flat washers will also be selected according to different uses. Therefore, the selection of materials also needs to be based on actual needs.

When purchasing, we must have some understanding of the materials of flat washers, Only in this way can a suitable flat washer be purchased.
