China Stainless Steel Fastener and Screw Nut Bolt

Product Description

Product Description

Fasteners are a type of mechanical parts used to connect two or more parts together. There are a wide variety of them, including bolts, nuts, screws, washers, rivets, pins, and many other types. Each type is further subdivided into numerous specifications and models according to different standards and application scenarios. They are usually made of materials such as carbon steel, alloy steel, stainless steel, copper alloy, and aluminum alloy to meet the requirements for characteristics like strength, corrosion resistance, electrical conductivity, and weight in different environments and working conditions. 

Product Features

2) Diverse Material Options
3) Precise Dimensional Accuracy
4) Good Universality and Interchangeability

Product Parameters

 

1. Bolts and Nuts

Thread Specifications	They cover metric threads (M) ranging from M2 to M64 and above, and imperial threads (UNC, UNF, etc.) ranging from 1/4" to 4". The pitch is precisely set to meet the needs of different thickness connections and ensure accurate matching with corresponding nuts, suitable for fastening connections of various types of equipment and structures.
Dimension Parameters	The length of bolts ranges from 5mm to over 1000mm, and the diameter ranges from 2mm to 64mm or larger. The dimensions of nuts, such as height and width across flats, are designed accordingly based on bolt specifications for precise adaptation to ensure the stability and reliability of the connection.

2. Screws
 

Thread Specifications	They also include multiple metric and imperial specifications. For example, metric threads M1.6 - M12 are commonly used in electronic products, furniture, and other fields. They have a fine thread design for easy and quick screwing in and providing reliable fastening force, meeting the requirements for fastening accuracy and efficiency in different occasions.
Head Types and Dimensions	There are a variety of head shapes, including pan heads, countersunk heads, round heads, hexagonal heads, Phillips slots, slotted heads, etc., to adapt to different installation spaces and aesthetic requirements.

3. Washers
 

Size Specifications

The inner diameter ranges from several millimeters to dozens of millimeters. The outer diameter is reasonably designed according to the inner diameter and application scenarios. There are multiple choices for thickness, from thin washers for precision connections to thick washers for occasions where relatively large pressure needs to be withstood. They can effectively increase the contact area, distribute pressure, prevent loosening, and provide cushioning and sealing effects, ensuring the stability and reliability of the connection parts.

Material Grades

We provide washers made of various materials such as carbon steel, stainless steel, rubber, and plastic. Different materials have different characteristics.

4. Rivets and Pins
 

Dimension Parameters

The length and diameter of rivets are determined according to the thickness and strength requirements of the connected plates, with supplies ranging from 2mm to 20mm and above. The diameter of pins ranges from 1mm to 20mm, and there are also multiple specifications for length. They can be used for positioning, connecting, and transmitting torque, ensuring the precise matching and stable connection between components.
