Thread Locker Locking Screw
Product Overview
Thread locker locking screws are advanced engineered fasteners designed to provide enhanced resistance to loosening under vibration and dynamic loads. These screws are pre-applied with a thread locking patch, adhesive, or mechanical locking feature that eliminates the need for additional locking elements, ensuring long-term joint reliability. Especially useful in high-performance and mechanically demanding applications, thread locker locking screws are a preferred choice in industries requiring secure fastening solutions.
At Flybear Fastener, we offer a wide range of thread locker locking screw options suitable for applications across automotive, aerospace, industrial machinery, and electronic sectors. Manufactured according to global standards and optimized for performance, our screws provide exceptional consistency, strength, and resistance to corrosion and wear.

Material and Manufacturing Process
Our thread locker locking screws are primarily manufactured using premium-grade alloy steel (Grade 8.8, 10.9, 12.9) and corrosion-resistant stainless steel materials such as 304 and 316. Each material type is carefully selected for its mechanical performance, temperature resistance, and environmental adaptability.
The production process involves:
- Cold-heading the blanks for precise shape formation,
- Thread rolling for accurate and strong thread formation,
- Heat treatment for structural integrity based on the grade,
- Pre-application of locking adhesive or mechanical patch to desired specification,
- Surface treatment like zinc plating or Dacromet to improve rust resistance,
- Final inspection and packaging.
Common Applications and Industries
Thread locker locking screws are widely used in:
- Automotive assemblies (engine block, steering, brake systems),
- Aerospace structures needing vibration-resistant fasteners,
- Heavy-duty machinery and equipment for reliable joints,
- Electronics and consumer appliances avoiding loosening from small vibrations,
- Renewable energy systems like wind turbines or solar tracker mounts,
- Railways and construction equipment for safety-critical connections.

Thread Locker Locking Screw Selection & Purchase Guide
When choosing the right thread locker locking screw, consider the following parameters:
- Application environment (temperature, exposure to corrosion),
- Required strength class (8.8, 10.9, 12.9, etc.),
- Thread specifications and head style compatibility with mating parts,
- Locking mechanism preference: chemical (adhesive thread locker) or mechanical (nylon patch),
- Torque and preload requirements,
- Certifications needed (RoHS, REACH, automotive standards, etc.).
