Our set screw (also known as grub screw) is a core dedicated accessory for locating and fastening in industrial assembly. Featuring a headless design<\/b><\/strong>\u00a0with full-threaded shank and matched with drive slots including hexagon socket, slotted and cross recess, it tightens the connected parts directly through the tip after being screwed into the workpiece’s threaded hole. It achieves multiple functions of gap-free positioning, anti-loosening & anti-rotation, and axial fixation<\/b><\/strong>\u00a0without additional positioning parts, and is suitable for precise fastening and limiting of shafts, wheel sleeves, moulds and hardware accessories. Manufactured by cold heading, thread rolling and precision slot milling processes, it has full thread profiles and tight engagement. The tips are available in various styles such as flat end, cone end, cup end and ball end. It is adaptable to carbon steel, stainless steel and other materials with multi-process surface treatments, with a complete range of sizes and support for non-standard customization. Widely used in mechanical equipment, hardware moulds, transmission components, precision instruments and other scenarios, it is a standardized optimal solution for industrial precision locating and fastening.<\/p>\n

Core Product Advantages<\/b><\/strong><\/h2>\n
    \n
  1. <\/b>Headless Full-Thread Design for Precise Locating & Fastening<\/b><\/strong>No protruding head structure, the full-threaded shank can be fully screwed into the workpiece. It realizes gap-free positioning and anti-loosening & anti-rotation by tightening the connected parts through the tip, without occupying external space, suitable for fastening shaft sleeves, wheel discs and mould accessories in narrow assembly environments.<\/li>\n
  2. <\/b>Multiple Tip Styles for All-Scenario Fastening<\/b><\/strong>Standard equipped with tip structures including flat end, cone end, cup end and ball end. Flat end is suitable for surface contact and precise positioning; cone end for hard surface tightening and anti-slip; ball end for groove clamping and limiting. It can be flexibly selected according to the material of connected parts and fastening requirements.<\/li>\n
  3. <\/b>Precision Machining for Tight Engagement & No Slippage<\/b><\/strong>Made by cold heading and thread rolling processes with high-precision threads, it features full thread profiles and precise pitches. The drive slots are milled flat and burr-free, ensuring smooth screwing and stable torque transmission. No risk of thread slippage or loosening after fastening, guaranteeing positioning accuracy.<\/li>\n
  4. <\/b>High-Strength Materials for Torsion Resistance, Wear Resistance & Durability<\/b><\/strong>Optional materials include carbon steel, 201\/304\/316 stainless steel, etc. The integral one-piece forming has no weak points, with excellent torsion, tensile and shear resistance. It can withstand dynamic loads during equipment operation, without fracture or deformation for long-term use.<\/li>\n
  5. <\/b>Diversified Surface Treatments for Complex Working Conditions<\/b><\/strong>Support for surface treatments such as white zinc plating, color zinc plating, blackening, phosphating, dacromet, nickel plating and stainless steel natural finish, providing rust, corrosion, high and low temperature resistance. Adapt to various industrial working conditions such as dry, humid, outdoor and corrosive environments, extending service life.<\/li>\n
  6. <\/b>Full Specification Coverage for Wide Assembly Versatility<\/b><\/strong>Covers mainstream drive methods including hexagon socket, slotted and cross recess, with standard specifications of M4-M10<\/b><\/strong>in thread and 5-50mm<\/b><\/strong>\u00a0in length. It adapts to the fastening needs of different hole and shaft diameters, meeting both general industrial and precision assembly scenarios.<\/li>\n
  7. <\/b>Easy Operation & High Adaptability with Customization Support<\/b><\/strong>Compatible with common tools such as hexagon socket wrenches and screwdrivers for easy operation, and can be matched with automatic assembly equipment. Support for non-standard sizes, special thread pitches, customized tip structures, and precise mold opening according to workpiece drawings to meet personalized locating and fastening needs.<\/li>\n<\/ol>\n
