| High Light | CNC machined knurled hand tool screws ，non-slip knurl tool screws ，high durability manual fastening screws | ||
Knurled Hand Tool Screws, also known as knurl thumb screws, are precision manual fastening parts widely used for tooling fixtures, instrument equipment, and mechanical adjustment structures. Manufactured using high-quality carbon steel or 304 stainless steel materials, our screws are produced through cold heading and CNC precision machining processes.
The uniform knurled head provides excellent anti-slip performance, allowing quick tightening and loosening by hand without any tools. Featuring precise thread tolerance, stable locking force, and burr-free smooth surface, these hand-adjustment screws ensure flexible operation and reliable fixation. Both standard stock and custom non-standard sizes are available for various industrial equipment applications.
The precisely processed straight knurl pattern significantly increases surface friction, effectively preventing slipping during manual adjustment. Operators can easily tighten or loosen the screws without wrenches or screwdrivers, improving equipment debugging, assembly, and maintenance efficiency. Ideal for frequent adjustment scenarios.
Made of high-density industrial carbon steel or stainless steel, these screws offer high tensile strength and structural stability. Cold heading technology ensures compact internal structure, while CNC finishing guarantees standard smooth threads and tight fitting tolerance. They resist thread slipping, deformation, and loosening after repeated use, delivering superior durability compared to ordinary fasteners.
All knurled screws feature smooth, burr-free surfaces. Multiple surface treatments including zinc plating, nickel plating, black oxide, and polishing are available for anti-rust, anti-oxidation, and wear resistance. They perfectly meet industrial fastening requirements while maintaining neat and beautiful equipment appearance.
Our comprehensive customization services ensure perfect compatibility with your specific application requirements.
