M6*105mm Safety Wire Bolt

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

The M6×105mm Safety Wire Bolt is a specialized fastener designed for applications where vibration or rotation could cause standard bolts to loosen. Here’s a detailed description:

Key Features:

1. Thread Specifications:

   • Metric Thread (M6): The bolt has a 6mm diameter with a standard metric thread pitch (typically 1.0mm unless specified otherwise).

   • Length (105mm): The overall shank length is 105mm, measured from under the head to the end of the bolt.

2. Safety Wire Hole:

   • A small drilled hole (usually 1.2–1.6mm in diameter) through the head or shank allows for safety wire (lock wire) to be threaded through, securing the bolt in place.

   • Material & Finish:

     • Commonly made from stainless steel (A2/A4) for corrosion resistance or alloy steel (grade 8.8/10.9) for high-strength applications.

     • May feature finishes like plain, zinc-plated, or anodized for durability.

3. Head Style:

   • Typically features a hex head (ISO 4762) or clevis head for easy wrenching and wire attachment.

   • Some variants have a slotted or drilled head for safety wire passage.

4. Applications:

   • Used in aerospace, automotive, marine, and machinery where vibration resistance is critical (e.g., aircraft engines, rotor assemblies, or high-stress mechanical systems).

   • Prevents loosening by wiring multiple bolts together or to a fixed structure.

Standards & Compliance:

• May conform to MS/MIL-SPEC, NAS, or DIN standards for aviation/military use.

• Industrial versions may follow ISO 7380 or ANSI/ASME specifications.

Installation Notes:

• Safety wire is threaded through the hole and twisted tightly, then anchored to an adjacent bolt or fixed point.

• Proper wire routing ensures tension opposes the loosening direction.
