316 stainless steel DIN916 grub screws, spanning M3-M10 thread sizes with 4-50mm lengths, feature a concave end, hex socket drive, and headless design. Engineered as industrial stop fasteners, these set screws deliver exceptional corrosion resistance—ideal for harsh environments like saltwater, chemicals, and humidity. The headless concave end design enables flush mounting and secure positioning of components (e.g., gears, shafts, meters), preventing unintended movement. Perfect for machinery, marine equipment, instrumentation, and precision assemblies that demand reliable stop-and-position functionality.
Core Features & Advantages
316 Stainless Steel Durability: Crafted from high-grade 316 SS, offering superior corrosion, rust, and chemical resistance compared to 304 SS. Performs reliably in marine, chemical, and humid harsh environments, ensuring long-term structural integrity.
DIN916 Standard Compliance: Adheres to DIN916 specifications for headless concave end set screws, guaranteeing consistent thread precision, dimension accuracy, and compatibility with global industrial components and hex socket tools.
Headless Concave End Design: Headless structure allows flush installation without surface protrusions, while the concave end provides focused pressure for secure component positioning and anti-slip stop functionality.
Hex Socket Drive Precision: Hex socket drive enables accurate tightening in confined spaces, reducing slippage and drive damage. Compatible with standard industrial hex tools for efficient professional installation and adjustment.
M3-M10×4-50 Size Versatility: Covers diverse thread sizes (M3-M10) and lengths (4-50mm), catering to small precision parts to medium-duty industrial components, meeting machinery, instrumentation, and marine fastening needs.
