Safety wire bolt Half thread

Cold heading process is one of the new processes for pressure machining of less or no cutting
metal. It is a processing method that utilizes the plastic deformation of metal under the action of
external forces, and with the aid of molds, redistributes and transfers the volume of metal to form
the required parts or blanks. The cold heading process is most suitable for producing standard
fasteners such as bolts, screws, nuts, rivets, and pins.etc

A Safety wire bolt 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. Material:

   • 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.

Applications:

• 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.
