Slotted Screw
Slotted Screw (also known as Slotted Set Screw or Slotted Grub Screw) is a headless fastener engineered for secure positioning and fixation in mechanical, structural, and industrial applications. Crafted from 304 stainless steel, this screw features a slotted drive (compatible with standard flathead screwdrivers for easy installation) and a headless design (enabling flush mounting without protrusions). Its precise threading, smooth surface, and corrosion-resistant properties make it ideal for industries demanding durability, precision, and reliability—such as furniture assembly, machinery, and medical equipment.

Product Parameter
Key Specifications (Complies with GB/T 79 (Chinese National Standard for Set Screws)):
Example Specification:
M10×12: 10mm thread diameter × 12mm total length, 1.25mm pitch, 2.5mm slot width (matches the specification in the provided images).
Note:
Thread Nominal Diameter: Refers to the major diameter of the screw thread (e.g., M10 = 10mm).
Nominal Length: Total length of the screw (from the tip of the thread to the end of the shank).
Pitch: Distance between adjacent threads (standard coarse/fine threads for different diameters).
Slot Width: Width of the slotted drive (matches the size of the flathead screwdriver).
| Thread Nominal Diameter (M) | Nominal Length (mm) | Pitch (mm) | Slot Width (mm) |
| M3 | 10–30 | 0.5 | 1.2 |
| M4 | 10–30 | 0.7 | 1.4 |
| M5 | 10–30 | 0.8 | 1.6 |
| M6 | 10–30 | 0.8 | 1.6 |

Product Feature
Corrosion & Rust Resistance: Made of 304 stainless steel, it offers excellent resistance to moisture, chemicals, and harsh environments (e.g., food processing, marine applications).
Easy Installation: The slotted drive allows for quick, tool-friendly installation with a standard flathead screwdriver, reducing labor time and cost.
Flush Mounting: The headless design ensures a smooth, unobtrusive finish—ideal for applications where protrusions are unacceptable (e.g., furniture, electronics, and precision machinery).
Precision Craftsmanship: Clear, uniform threads prevent stripping and ensure secure fixation. The burr-free surface protects workpieces from damage during installation.
Customization & Service: Supports custom specifications (e.g., special lengths, materials, or thread types) to meet specific needs. In stock with fast delivery, and OEM/ODM services are available for bulk orders.
Application Fields
This slotted screw is widely used in industries requiring positioning and fixation, including:
Home Decoration: Furniture assembly (e.g., sofas, cabinets), hardware fixtures, and home improvement projects (flush mounting for a clean look).
Industrial Building Materials: Structural connections in steel frames, machinery, and heavy equipment (secure fixation of guides, pulleys, or fixtures).
Medical Equipment: Fixation of medical devices (e.g., surgical tools, hospital beds) and diagnostic equipment (precise alignment for critical components).
Food Industry: Food processing machinery (e.g., mixers, conveyors) and packaging equipment (304 stainless steel ensures food safety and hygiene).
Vehicle & Ship Parts: Automotive components (e.g., engine parts, chassis) and shipbuilding (e.g., propellers, navigation systems) (anti-vibration and anti-loosening performance).
Communication Industry: Fixation of communication devices (e.g., routers, switches) and server cabinets (flush mounting for compact designs).
Easy Installation: The slotted drive allows for quick, tool-friendly installation with a standard flathead screwdriver, reducing labor time and cost.
