304 Stainless Steel Slotted Adjusting Set Screw
,Precision Full Thread Headless Grub Screw
,Headless Hidden Design Slotted Drive Limit Fastener
Situo Hardware is a professional manufacturer specializing in stainless steel slotted adjusting set screws, headless slotted grub screws, slotted drive limit fasteners and non-standard precision positioning fasteners. We focus on the supporting fields of automation equipment, electromechanical instruments, tooling jigs, precision molds, transmission rotating shafts and industrial precision fine-tuning positioning.
This series of stainless steel slotted adjusting grub screws are high-precision headless hidden fine-tuning fasteners, also known as slotted machine screws and stop screws. Integrally precision-machined from high-quality 304 stainless steel, they adopt a full-thread structure with standard slotted drive grooves, compatible with common flat screwdrivers for easy assembly and debugging.
The headless hidden design can be completely embedded in threaded holes without protruding, avoiding interference with equipment operation and adapting to narrow and compact assembly spaces. With standard full threads and accurate pitch, the screws realize precise gap adjustment, tight locking and limit positioning for equipment rotating shafts and module components, effectively solving equipment loosening, displacement, gap deviation and abnormal noise problems.
Made of genuine SUS304 stainless steel with dense and pure texture, moderate hardness and excellent toughness. Superior rust resistance, oxidation resistance and moisture corrosion resistance suitable for various environments including indoor, outdoor, humid, dusty and slightly corrosive conditions.
Precision milled standard slotted groove with flat and uniform notch depth, perfectly matching universal flat screwdrivers. Enables simple disassembly, fine adjustment and locking without professional tools.
Integrated headless structure leaves no protruding part after installation, completely hidden inside threaded holes. Ideal for compact precision equipment, narrow assembly spaces and high-speed transmission modules.
High-precision thread rolling technology ensures full tooth profile, uniform pitch, no burrs or deformation. Fits standard threaded holes perfectly with tight engagement and minimal gap.
Various end face options including flat end, pointed end, cylindrical end and conical end available to meet diverse working requirements.
Customizable total length, shank diameter, thread pitch, slotted groove specification, end face structure and thread length. Special specifications supported including lengthened, ultra-fine and non-standard pitch screws.
Full-process standardized quality control includes material inspection, slotted groove precision calibration, thread go/no-go testing, end face flatness screening and full appearance inspection.
