Set Screw
Set Screw (also known as Hexagon Socket Grub Screw or Positioning Screw) is a precision fastener engineered for secure positioning and anti-rotation of mechanical components. Crafted from 304 stainless steel, this screw features a hexagonal socket drive (for high-torque installation) and a sharp cup point (concave tip) (for accurate alignment with mating parts). To enhance reliability, threadlocker is applied to the threads, effectively preventing loosening caused by vibration, shock, or repeated use. Complies with GB79 (Chinese National Standard for Hexagon Socket Set Screws), ensuring consistent quality and compatibility with industry requirements. Its headless design enables flush mounting, making it ideal for applications where protrusions are unacceptable (e.g., precision machinery, electronics).

Product Parameter
Key Specifications (Complies with GB79):
Nominal Diameter (e.g., M6): Refers to the thread diameter (6mm for M6).
Length: Total length of the screw (from tip to end of the thread).
Pitch: Distance between adjacent threads (1.0mm for M6 series, standard coarse thread).
| Nominal Diameter (M) | Length (mm) | Pitch (mm) |
| M6 | 7.2 | 1.0 |
| M6 | 8.0 | 1.0 |
| M6 | 9.0 | 1.0 |
| M6 | 10.0 | 1.0 |
| M6 | 12.0 | 1.0 |

Product Feature
Durable & Corrosion-Resistant: Made of 304 stainless steel, it offers excellent rust resistance, chemical resistance, and mechanical strength, suitable for harsh environments (e.g., food processing, marine applications).
Precision Positioning: The sharp cup point ensures accurate alignment with mating parts, while the hexagonal socket provides high torque for secure installation (prevents slippage during use).
Anti-Loosening Reliability: Threadlocker is applied to the threads, creating a strong bond that resists loosening from vibration or repeated tightening/loosening. This extends the service life of the fastener.
Superior Craftsmanship: Clear, uniform threads (no burrs or defects) ensure smooth installation and prevent damage to workpieces. The polished surface (bright finish) enhances aesthetics and corrosion resistance.
Wide Specification Range: Available in M6 series with multiple lengths (7.2mm to 12mm), meeting diverse application needs. Manufacturer direct supply and customization services (e.g., special lengths, materials) are available to suit specific requirements.
Application Fields
This set screw is widely used in industries requiring precise positioning and anti-rotation, including:
Machinery & Automation: Machine tools (e.g., lathes, milling machines), conveyor systems, and robotic arms (positioning of guides, pulleys, and fixtures).
Automotive Industry: Engine components (e.g., cylinder heads, camshafts), chassis parts (e.g., suspension brackets), and transmission systems (securing gears, bolts, and bearings).
Electronics: Communication devices (e.g., routers, switches), computers, and home appliances (fixing casings, brackets, and internal components).
Furniture Assembly: Sofas, cabinets, and home improvement projects (securing hinges, handles, and structural parts).
Medical Equipment: Surgical tools (e.g., forceps, scissors), hospital beds, and diagnostic devices (fixing parts that require precise alignment).
Other Applications: Any occasion where parts need to be positioned accurately and prevented from rotating relative to each other (e.g., agricultural machinery, aerospace components).
