304 Stainless Steel Hex Socket Set Screw
,Headless Design Grub Screw
,Precision Full Thread Adjustment Set Screw
Situo Hardware is a professional manufacturer specializing in 304 stainless steel hex socket adjustment set screws, headless grub screws, precision limit fasteners and non-standard mechanical positioning fasteners. We serve automation equipment, electromechanical machinery, tooling jigs, precision molds, transmission modules and industrial shaft locking positioning.
This series of 304 stainless steel hex socket grub screws are high-precision headless limit fasteners, also known as machine rice screws and stop screws. Integrally machined from high-quality 304 stainless steel, they feature full-thread and standard hex socket structure, supporting precise fine adjustment, gap control and shaft locking positioning.
The headless hidden design can be completely embedded in the mounting hole without occupying space or interfering with equipment operation. With standard full threads and smooth engagement, the screws accurately fix and adjust mechanical shafts and module components, effectively solving common problems such as shaft displacement, loosening, gap deviation and abnormal operating noise.
Made of genuine SUS304 stainless steel with excellent rust resistance, oxidation resistance and corrosion resistance. Adapts to humid, dusty, outdoor and slightly corrosive environments with longer service life than ordinary carbon steel screws.
Integrated headless design completely hidden inside threaded hole after installation. No protruding surface prevents interference with equipment transmission and avoids scratch and collision risks.
Precision formed standard hex socket ensures uniform stress bearing. Compatible with standard hex wrenches for easy disassembly and debugging, preventing hole collapse and thread slipping.
High-precision thread rolling technology with full tooth profile and uniform pitch. Perfectly matches standard threaded holes with tight engagement and minimal gap.
Multiple end face types including flat end, pointed end, cylindrical end and conical end. Meets diverse working needs for shaft jacking, plane limiting, anti-loosening clamping and precise positioning.
Customizable total length, shank diameter, thread pitch, end face structure and thread length. Special specifications available for personalized equipment demands.
Full-process standardized quality control including raw material screening, thread testing, hex socket calibration and full appearance screening. Excellent interchangeability for mass industrial assembly.
- Limit locking and gap fine adjustment for transmission shafts and precision module shafts of automation equipment
