Product Features and Functions
Manual Adjustment Function
The knurled head design allows for precise fine-tuning of equipment parameters using a knurled adjusting screw.
Anti-Loosening and Positioning
With nylon locking washers or self-locking threads, it maintains a tight fit even under vibration, preventing loosening.
Panel Mounting Adaptation
As a knurled panel screw, it can be directly embedded into the equipment panel without additional nuts, simplifying the installation structure.
Multi-Scenario Versatility
Compatible with metric/imperial threads, the Thumb Screw with Knurled Head adapts to the assembly needs of various substrates such as metal, plastic, and composite materials.
Manufacturing Process
| Raw Material Selection | The knurled round head thumb screw uses high-quality bars from leading steel mills, undergoing spectral analysis and mechanical property testing before entering the factory. |
| Precision Machining | CNC turning and knurling are used in one piece to ensure the head and thread coaxiality of the knurled flat head thumb screw is ≤0.01mm; cold heading process improves thread strength and prevents cracking. |
| Surface treatment | Passivation, electroplating, electrophoresis, and other processes are used to meet the corrosion resistance and appearance requirements of knurled thumb screws. |
| Full inspection process | Each batch of knurled head screws undergoes optical sorting to inspect dimensions, threads, and knurling quality, with a defect rate controlled below 0.1%. |
