Grade 12.9 Triple Security Cap Screws/ Anti-Tamper & Vibration Proof/ Machinery & Energy/ Batch Orders Guanbiao Hardware

Industrial grade 12.9 alloy steel security cap screws. Three-combination defense: TR drive, chemical threadlock & mechanical locker. For vibration-prone machinery, energy & automation. Dacromet coated.

Secure critical machinery components against vibration loosening and tampering with our industrial-grade **Three Combination Security Cap Head Hex Socket Screws**. Combining 1) A **tamper-resistant pin-in-hex drive**, 2) A **high-performance pre-applied threadlocker** (chemical), and 3) An **integrated mechanical locking feature** (e.g., deformed threads, patch), these fasteners deliver maximum clamp force retention and security in demanding industrial environments like energy generation, heavy automation, and high-vibration equipment. Manufactured from ultra-high-strength alloy steel.

Primary Uses & Applications:
* Power generation equipment (turbines, generators, transformers).
* Heavy machinery frames, guards, and critical linkages.
* Robotics and high-precision automation assemblies.
* Mining and oil & gas drilling equipment.
* High-vibration motors, pumps, and compressors.
* Security panels on industrial control systems.
* Permanent fixturing in manufacturing lines.

Surface Treatment/Finishes:
* **Dacromet / Geomet® (Zinc Flake Coating):** Superior corrosion resistance (500-1000+ hrs salt spray), excellent heat resistance (>300°C), lubricity for accurate torque-tension, RoHS compliant. *Ideal for industrial harsh environments.*
* **Black Oxide:** Mild corrosion resistance, good lubricity, reduces glare.
* **Phosphate & Oil:** Good lubricity and mild corrosion resistance.
* **(Optional) Xylan®/PTFE Topcoat:** Added lubricity and chemical resistance over base coating.

How to Use:

1. **Prepare:** Clean male and female threads thoroughly. Remove heavy oils/grease (light oil from coating is usually acceptable). Ensure female threads are in good condition.
2. **Insert Screw:** Use the **correct TR driver bit** (e.g., TR40 for M12). Insert the screw. The mechanical lock (deformed threads/patch) will provide initial resistance.
3. **Tighten:** Apply torque steadily using a calibrated torque wrench/driver. Tighten to the **specified torque value for Grade 12.9** and the specific coating. The threadlocker activates upon curing (anaerobically).
4. **Removal:** Requires the correct TR driver bit and significant torque (overcoming cured threadlocker and mechanical lock). May damage threads. Not designed for frequent disassembly. *Considered semi-permanent in demanding applications.*
5. **Reuse:** **Not Recommended.** The threadlocker's effectiveness and mechanical lock are significantly compromised after removal.
