304/316 Stainless Steel GB70.1 machine screws are premium precision fasteners engineered with a hex socket drive, cylinder cup head, non-knurled design, and optional full/half thread options, tailored for industrial, commercial, and precision assembly applications. Crafted from high-quality 304 and 316 stainless steel, these screws offer exceptional corrosion resistance—with 316 grade providing enhanced durability in harsh, high-moisture, or chemical environments, making them versatile for indoor, outdoor, and industrial scenarios like machinery installation, equipment fixtures, and precision component assembly.
The cylinder cup head delivers a smooth, compact profile that ensures even load distribution for secure fixation, while the non-knurled design maintains a clean aesthetic and avoids unintended friction with adjacent components. The hex socket drive enables easy installation and removal with standard tools, ensuring stable torque transmission even in confined spaces. Available in full-thread and half-thread variants, they adapt to diverse needs: full-thread for maximum engagement with tapped holes, half-thread for enhanced stability in thicker workpieces.
Fully compliant with GB70.1 standards, these screws guarantee consistent dimensional accuracy, thread precision, and universal compatibility with standard industrial components. Built for long-term reliability, they resist rust, wear, and oxidation, balancing functional performance with broad applicability for professionals and industrial projects.
