A 安全線螺栓 Half thread is a specialized fastener designed to secure components in critical applications where vibration or movement could cause loosening. Here’s a detailed description:

Features:

1. Half-Threaded Design:

   • The bolt has a threaded portion (typically near the head) and a smooth shank section.

   • The unthreaded portion provides shear strength, while the threaded section allows for secure fastening.

2. Safety Wire Hole:

   • A small drilled hole (usually near the head or at the threaded end) allows for the insertion of safety wire (locking wire).

   • The wire is looped through adjacent bolts or a fixed structure to prevent rotation and loosening.

3. 材質：

   • Often made from high-strength materials like stainless steel (A2/A4), alloy steel (grade 8.8/10.9), or titanium for corrosion resistance and durability.

4. Thread Type:

   • Common thread standards include metric (M-series) or imperial (UNC/UNF).

   • The threaded portion may be fully or partially engaged depending on the application.

   • Safety wire bolt Half thread

5. Head Styles:

   • Available in hex head, socket head cap screw (SHCS), or other aviation/aerospace-specific designs.

應用：

• Aerospace & Aviation: Engine components, landing gear, and rotor assemblies.

• Automotive & Racing: High-vibration areas like suspension and drivetrain.

• Industrial Machinery: Critical bolted joints subject to dynamic loads.

Safety Wiring Method:

• The wire is threaded through the bolt hole and twisted tightly to an adjacent fastener, ensuring tension prevents rotation.

• Proper wiring follows clockwise tightening direction to avoid loosening under torque.

This bolt ensures fail-safe security in high-risk environments where traditional locking methods (like nuts or washers) may fail.
