M6*40mm 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

An M6*40mm safety wire bolt is a specialized fastener designed to be secured with safety wire to prevent loosening under vibration or rotation. Here’s a detailed description:

Key Features:

1. Thread Size (M6)

   • Metric coarse thread (standard pitch: 1.0mm).

   • Diameter: 6mm (shank size).

2. Length (40mm)

   • Total length (likely measured from under the head to the tip).

   • Thread length may vary (typically ~16mm for standard M6 bolts).

3. Head Design

   • Usually has a hex head (e.g., M6 hex bolt) or clevis head for safety wiring.

   • May include a drilled hole (typically 1.2–1.6mm diameter) through the head or shank for wire passage.

4. Material & Finish

   • Common materials: Stainless steel (A2/A4), carbon steel (grade 8.8/10.9), or titanium.

   • Finish: Plain, zinc-plated, or anodized (for corrosion resistance).

5. Safety Wire Function

   • Used in pairs or with other components, wired together to resist rotation.

   • Common in aviation, motorsports, and machinery exposed to high vibration.

Applications:

• Aircraft engine components.

• Motorcycle brake systems.

• High-performance machinery requiring vibration resistance.

• M6*40mm Safety Wire Bolt

Standards:

• May comply with MS, NAS, or AN specifications (aviation-grade bolts).

If you need a specific type (e.g., drilled head, shoulder bolt), confirm details with the manufacturer/supplier. Let me know if you’d like further clarification!
