Set Screw
Hex Socket Set Screw Stainless Steel Alloy Steel Grub Screw Multiple Point Types For Industrial Machinery Auto Robot Wholesale Manufacturer
Set Screw, also named grub screw, is a headless threaded fastener designed to lock gears, pulleys, shaft collars and precision parts without protruding surface obstruction. Our factory produces full-series Set Screw covering stainless steel and high-strength alloy steel material, with multiple end point designs to match diverse industrial working conditions.
Unlike ordinary standard fasteners, our Set Screw adopts strict ±0.02mm dimensional tolerance control, effectively solving the core pain points of loose parts, sliding shafts and inaccurate positioning that industrial buyers often encounter. All Set Screw comply with DIN913/DIN914/DIN915/DIN916 international standards, supporting metric and inch custom sizes for machinery, new energy vehicle, robot, mold and electronic equipment industries.
