Precision screws

Small screws are miniature fasteners used to connect products with tiny shapes, but they play a crucial role in connecting key components. They are widely used in electronics, electrical appliances, furniture, mechanical equipment, etc.

 

Precision screws need to be hardened.

The rigidity of precision screws on products usually becomes hard. Because many untightened precision screws are easy to slide or break during use. The most fundamental reason for thread slippage and breakage is that precision screws are not hard enough. Therefore, it is necessary to harden precision screws with hardness requirements.

 

Different precision screw materials.

Precision screws are made of carbon steel and stainless steel. Carbon steel precision screws are generally made of steel wire, and the materials are low-carbon steel, medium-carbon steel, and high-carbon steel. The wire material is 1010A, 1018, 10B21, 45 steel, etc.

Stainless steel precision screws are usually made of stainless steel wire. The materials are stainless steel 201, stainless steel 304, stainless steel 410, stainless steel SUS316, stainless steel SUS404, and so on.

 

The plating of precision screws is different.

Electroplating of precision screws usually refers to carbon steel precision screws, and stainless steel precision screwstypically doo not require electroplating unless required by the customer.

 

Precision screw plating is divided into environmental protection and non-environmental protection.
