Hex Head Nylon Patch Anti-Loose Bolt (Blue & Orange Thread Lock Coating)

1. Product Overview

Our hexagon head nylon patch anti-loose bolts are professional locking fasteners specially designed for vibration-intensive equipment. Blue or orange nylon coating is evenly applied to screw threads. After tightening, the nylon layer forms tight friction locking between threads, which can effectively stop bolt loosening caused by long-term vibration, impact and temperature fluctuation.

These bolts are manufactured from high-strength carbon steel and stainless steel via precision cold forging and CNC thread machining. Strict heat treatment ensures high surface hardness, outstanding tensile strength and shear resistance. We provide full standard metric sizes, and support customized non-standard length, thread diameter, nylon coating color and surface treatment as customer demands.

2. Core Product Advantages

1. Stable Anti-Locking Effect: Nylon patch creates lasting friction lock, no loose failure under continuous mechanical vibration.

2. Dual Material Selection: Carbon steel for high cost performance and high strength scenarios; stainless steel for rust-proof, damp and corrosive working environments.

3. Integrated Sealing Function: Nylon filling thread gaps to block water, oil and dust penetration for sealed assembly requirements.

4. Simple & Fast Installation: Matched with standard hex wrench tools, easy to install and disassemble for maintenance.

5. Flawless Precision Machining: Smooth thread without burrs, will not scratch matching metal workpieces during assembly.

3. Wide Application Fields

Hex head nylon patch anti-loose bolts are widely used as permanent locking fasteners in multiple industries: automotive parts, engineering construction machinery, automation equipment, electrical cabinets, metal frames, precision instruments and heavy industrial hardware. They are the ideal fastener choice for all equipment positions prone to vibration loosening.

4. Factory Strength

We are a professional fastener manufacturer with complete integrated production lines, including cold heading, precision turning, nylon patch coating, polishing and surface anti-rust treatment. Every batch of bolts undergoes strict factory inspection: tensile test, shear force test, salt spray corrosion test and vibration anti-loosening test to guarantee stable quality.

We accept OEM and ODM customization, offer factory direct wholesale price and stable mass supply for global hardware distributors and manufacturing enterprises.
