Tianqi Fasteners offers a comprehensive range of high-precision Stainless Steel Set Screws, designed for secure, headless fastening in demanding mechanical and industrial applications. These versatile fasteners—available in both 304 Stainless Steel for general use and marine-grade 316—are engineered to fix components like pulleys, gears, and collars onto shafts with absolute stability. From the precision-locking 316 Stainless Steel DIN913 Hexagon Socket Set Screw to specialized designs like the Slotted Head Cone Point Set Screw and the Flat End Slotted Head Set Screw, our selection ensures a flush, snag-free finish while providing the specific “bite” or surface protection required for your project. Whether you need the high-torque grip of a Hexagon Set Screw With Concave End or the simple adjustment of a slotted drive, our set screws deliver the ultimate balance of corrosion resistance and mechanical reliability.
Manufactured from premium 304 Stainless Steel and 316 alloys, our set screws are built to withstand oxidation, moisture, and harsh chemical exposure without rusting or seizing.
The Slotted Head Cone Point Set Screw provides a deep “bite” for permanent positioning. The Flat End Slotted Head Set Screw ensures non-marring contact for delicate surfaces. The Hexagon Set Screw With Concave End (Cup Point) offers maximum vibration resistance by digging into the mating surface.
Choose between the high-torque capability of the 316 Stainless Steel DIN913 Hexagon Socket Set Screw for power-tool installation or traditional slotted drives for easy field adjustments with standard tools.
The “grub screw” design allows the fastener to be driven entirely into a threaded hole, ensuring a flush surface that prevents mechanical interference and provides a clean, professional finish.
Precision-rolled threads ensure consistent torque distribution and prevent stripping, even in high-load industrial environments.
