Adhesive Coated Stainless Steel Screw
Adhesive Coated Stainless Steel Screw (alias: Adhesive Set Screw, Glue-Coated Machine Screw) is a high-precision fastener designed for vibration-resistant and anti-loosening applications, combining mechanical locking and chemical anti-loosening functions. Crafted from 304/201 premium stainless steel (containing chromium and nickel, anti-oxidation, acid-alkali resistant), the screw is treated with blue anaerobic adhesive (applied to the middle section of the thread). The adhesive fills the thread clearance, forming a "mechanical + chemical" dual-locking structure to effectively prevent loosening caused by vibration, impact, or repeated disassembly.

Product Parameter
The following are common metric specifications (non-standard customization is available, e.g., adjusting thread length, adhesive position):
Note: Specification is expressed as "Nominal Thread Diameter×Length" (e.g., M6×8 means nominal thread diameter 6mm, length 8mm); pitch complies with ISO 68-1, and hexagon socket size fits universal tools.
| Nominal Thread Diameter (M) | Nominal Length (mm) | Pitch (mm) | Hexagon Socket Size (mm) | Adhesive Position | Adhesive Width (mm) |
| M5 | 5 | 0.8 | 2.5 | Middle of thread | 1.0-2.0 |
| M6 | 5 | 1.0 | 3.0 | Middle of thread | 1.0-2.0 |
| M6 | 8 | 1.0 | 3.0 | Middle of thread | 1.0-2.0 |
| M8 | 8 | 1.25 | 4.0 | Middle of thread | 1.5-2.5 |

Product Feature
Dual Anti-Loosening, Reliable & Stable:
The blue anaerobic adhesive fills the thread clearance, creating a "mechanical locking + chemical bonding" dual anti-loosening structure. This improves vibration and impact resistance by over 50% compared to ordinary screws, ensuring no loosening even in high-frequency vibration environments (e.g., automotive engines, machine tool spindles).
Corrosion-Resistant, Long Service Life:
304/201 stainless steel offers excellent corrosion resistance (to atmospheric corrosion, organic/inorganic acid erosion). The adhesive further isolates moisture and chemicals, making it suitable for humid or corrosive environments (e.g., food machinery, outdoor facilities).
High Precision, Easy Installation:
The hexagon socket (compliant with ISO 4762) fits tightly with wrenches/electric tools, ensuring high torque transmission efficiency (max torque: 15N·m). The pointed end allows quick positioning and insertion into mounting holes, ideal for high-precision assembly (e.g., electronic devices, precision machinery).
High Strength, Suitable for Heavy Loads:
Stainless steel has a tensile strength of ≥520MPa (304)/≥500MPa (201), capable of withstanding medium to heavy loads (e.g., mechanical equipment, vehicle & ship parts) without deformation or fracture.
Customization Service:
The factory supports non-standard customization (e.g., adjusting adhesive color, thread parameters, length) and provides free samples to meet special customer needs (e.g., irregular part fixation, high-corrosion environments).
Application Fields
Home Decoration: Used for assembling furniture (e.g., sofas, wardrobes, bookshelves) to fix connectors (e.g., hinges, slides). The anti-loosening design ensures furniture stability, and the stainless steel material is aesthetically pleasing and corrosion-resistant.
Industrial Building Materials: Used for connections in steel structure buildings, scaffolding, and railway facilities. The high-strength and anti-loosening design withstands heavy loads and vibration, ensuring structural safety.
Medical Equipment: Used for fixing medical devices (e.g., operating tables, imaging equipment, rehabilitation devices). The 304 stainless steel complies with medical hygiene requirements (no harmful substance leaching), and the anti-loosening design ensures stable device operation.
Food Industry: Used for assembling food processing machinery (e.g., packaging machines, conveyor lines, mixers). The 304 stainless steel is corrosion-resistant (against food raw material erosion) and easy to clean, complying with GB 14930.1 food-grade hygiene standards.
Vehicle & Ship Parts: Used for fixing engine components (e.g., cylinder heads, camshafts), chassis parts (e.g., suspension brackets, drive shafts) in automobiles/ships. The anti-vibration and anti-loosening design ensures stable operation.
Communications Industry: Used for internal part fixation in communication equipment (e.g., base stations, switches, routers). High-precision assembly does not affect device performance, and the anti-loosening design prevents part displacement.
