Knurled Head Cylindrical Pin Screw

Product introduction

Knurled head cylindrical pin screw is a high-performance hardware with both fastening and positioning functions. Its unique cylindrical pin-shaped rod can achieve a tight fit with the precision holes on the base body, providing precise positioning and shear resistance, effectively preventing misalignment between components.

 

The head of the screw is designed with knurled teeth, which greatly increases the friction coefficient, making it easy to screw by hand or provide excellent anti-loosening performance in high-vibration environments. The surface nickel plating treatment not only gives the product a bright and beautiful metallic luster, but more importantly, it provides excellent anti-corrosion and anti-rust capabilities, and can enhance surface hardness and wear resistance, extending the service life. This product is widely used in mechanical equipment, precision instruments, mold tooling and other fields that require high-precision positioning and reliable fastening. It is an indispensable key connector in industrial manufacturing.

 

Product Features

1. Precise positioning and shear resistance: Its cylindrical pin-shaped rod is tightly matched with the precise hole position of the base body. Its core function is to accurately fix the relative position between components, and can effectively withstand and resist lateral shear forces to prevent component displacement.

2. Convenient manual operation and anti-loosening: The unique knurled head design provides great surface friction, making it easy to manually screw even in situations where tools are inconvenient or quick debugging is required. At the same time, the knurled pattern can play an excellent role in preventing loosening in high vibration environments.

3. Corrosion resistance and high hardness surface: Nickel plating on the surface not only gives the product a silvery and beautiful appearance, but also forms a dense protective layer that can effectively resist oxidation, corrosion and rust. The coating also improves surface hardness and wear resistance, extending service life.

4. Wide application, stable and reliable: It combines the positioning function of "pin" and the fastening function of "screw" into one, simplifying the structural design. This makes it an indispensable key component in fields that require extremely high precision and stability, such as mechanical equipment, precision instruments, molds and fixtures.

 

Product application

1. Precision machinery and equipment manufacturing: used to fix precision components such as transmission gears, bearing seats, and optical lens barrels. Function: The cylindrical pin rod achieves precise radial positioning to ensure concentricity and axis position; the threaded part provides axial tightening force; the knurled head facilitates debugging and prevents vibration loosening.

2. Molds and tooling fixtures: used as mold guide posts, positioning pins and quick locking components in fixtures. Function: Ensure the accuracy of mold closing or the repeatable positioning accuracy of workpieces during processing. The nickel plating layer can resist corrosion from coolant and grease and reduce wear.

3. Electronic instruments and precision mechanisms: used for the connection and positioning of internal components such as precision measuring instruments, optical equipment, robot joints, etc. Function: Provide reliable manual adjustment and tightening solutions in situations where space is limited and high precision and vibration resistance are required.

4. Automation equipment and assembly lines: installed on conveyor belt mechanisms, assembly robotic arms and other equipment. Function: In an environment of continuous vibration, its anti-loosening characteristics are particularly outstanding, which can maintain positioning accuracy for a long time and reduce maintenance frequency.

 

FAQ

Q: Does the knurled head design of this screw have other functions besides being convenient for hand tightening?

A: Yes. In addition to being easy to operate by hand, the knurled teeth can effectively increase friction and provide excellent anti-rotation (anti-loosening) performance, especially when subjected to vibration, to maintain a locked state.

 

Q: What is the function of the cylindrical pin segment? How is it different from threads?

A: The cylindrical pin segment is a polished rod with a precise diameter. Its main function is precise positioning to ensure the concentricity and axial position of the connected parts. The thread segment is mainly responsible for providing tightening force. It realizes the integration of positioning and fastening functions.

 

Q: Under what circumstances is it best to use knurled head pin screws?

A: Mainly suitable for the following scenarios: parts that require frequent manual adjustment or quick disassembly. The space is small and tools cannot be used. Where precise axial positioning and reliable fastening are required at the same time, such as rotating parts in fixtures and instruments.
