M6*80mm 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*80mm Safety Wire Bolt is a specialized fastener designed for applications where vibration or movement could cause standard bolts to loosen. Here’s a detailed description:

Key Features:

1. Thread Size (M6):

   • Metric coarse thread with a 6mm nominal diameter and a standard pitch (typically 1.0mm unless specified otherwise).

2. Length (80mm):

   • Shank length = 80mm (measured from under the head to the end of the bolt).

3. Head Type:

   • Usually has a hex head (e.g., hexagonal, DIN 933/ISO 4017) or another style (like a drilled-head bolt) to allow for wrench tightening.

4. Safety Wire Hole:

   • A small hole (typically 1-2mm in diameter) drilled through the head or shank to thread safety wire (lock wire).

   • Prevents rotation/loosening by tying adjacent bolts together or securing to a fixed point.

5. Material:

   • Common materials include stainless steel (A2/A4) for corrosion resistance or alloy steel (grade 8.8/10.9) for high strength.

   • May have coatings like zinc plating or black oxide for protection.

   • M6*80mm Safety Wire Bolt

6. Standards:

   • May comply with MS/MIL-SPEC standards (e.g., MIL-DTL-1222) for aerospace/military use or industrial norms like DIN/ISO.

Applications:

• Aircraft/aviation (engine components, landing gear).

• Motorsports (critical engine/structural bolts).

• Military/defense equipment.

• High-vibration machinery (pumps, turbines).

Installation Notes:

• Safety wire is threaded through the hole and twisted/wrapped to adjacent bolts in a specific pattern to resist loosening.

• Proper torque must be applied before wiring to ensure clamping force.
