Knurled Thumb Nut
Products Description
The core value of knurled thumb nuts lies in:
Quick tightening and loosening without tools
The non-slip knurled design ensures good grip even with wet or oily hands
High-reliability brass material ensures fastening strength and corrosion resistance
These knurled nuts are particularly suitable for applications requiring frequent adjustments, no torque tools needed, and quick disassembly, making them a typical example of fasteners that combine functionality and ease of use in engineering structures.
Material Advantages: High-Performance Brass for Structural and Lifespan Guarantee
1. High-Purity Brass (CuZn Alloy)
Stable strength, not easily deformed under long-term load.
Significantly superior corrosion resistance compared to ordinary steel.
Good machinability ensures a more stable thread quality.
Compared to: Aluminum > Lower strength;
Compared to: Iron > Prone to rust;
Compared to: Plastic > More resistant to temperature and pressure, longer lifespan.
The addition of brass makes this product more suitable for long-term outdoor use, humid environments, and low-vibration conditions.
2. Conductivity Meets the Requirements of Low-Voltage Structures
In instruments, meters, electronic terminals, etc., brass knurled nuts can serve as grounding structures or low-current load connection components, achieving the dual function of structural fixation and functional conductivity.
Exquisite Manufacturing Process: An Artistic Journey from Copper Rods to Precision Interactive Interfaces
Precision Cutting of Environmentally Friendly Brass Rods
We select high-purity, RoHS-compliant, environmentally friendly brass rods and use high-precision automatic cutting machines to ensure that the length and end-face perpendicularity of each blank meet standards.
Cold Heading and Machining
The basic shape of the butterfly wing is formed in one step using a multi-station cold heading machine, ensuring the continuity and strength of the metal fibers. For more complex shapes, precision CNC turning is used to ensure accurate dimensions and geometric tolerances.
High-Precision Knurling and Threading
Using specialized knurling machines and thread rolling machines, high-hardness knurling wheels and rolling plates are used to knurl clear, uniform textures and threads onto the surface of the blank in one pass. This cold working method is not only highly efficient but also enhances surface hardness and improves wear resistance.
Surface Finishing and Quality Inspection
Depending on requirements, surface treatments such as vibratory polishing, sandblasting, passivation, or electroplating (e.g., nickel plating, chrome plating) can be performed to achieve the desired gloss and corrosion resistance. Finally, each product undergoes inspection for appearance, dimensions, thread gauges, and tactile feel.
