Color classification
Stainless Steel UNC/UNF Set Screws are precision headless fasteners engineered with a hex socket drive, concave end, and dual coarse/fine thread options, designed for inch-standard industrial, mechanical, and equipment applications. As US-standard fasteners, they adhere to UNC (Unified National Coarse) and UNF (Unified National Fine) thread specifications, catering to diverse torque and precision requirements for securing components, shaft locking, and part positioning.
 
Crafted from high-quality stainless steel, these headless set screws offer excellent corrosion resistance, rust prevention, and structural durability, making them suitable for indoor, outdoor, and mild-moisture environments like machinery assembly, tool fixtures, automotive parts, and precision equipment maintenance. The concave end ensures tight contact with target surfaces, delivering reliable locking performance without damaging workpieces, while the hex socket drive enables stable torque transmission with standard tools for efficient installation and adjustment.
 
Available in coarse and fine thread variants, they provide flexible 适配 for different load-bearing and precision positioning needs. The headless design offers a low-profile finish, avoiding interference with adjacent components and maintaining a clean aesthetic in assembled structures. Fully compliant with US inch standards, these set screws guarantee consistent dimensional accuracy and broad compatibility with inch-standard industrial parts.
