M5*10mm 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

Overall Description: M5×10mm Safety Wire Bolt

The M5*10mm safety wire bolt is a specialized fastener designed to remain secure in high-vibration or high-movement environments by using safety wire (lock wire) to prevent loosening. It is commonly used in aerospace, automotive (motorsports), industrial machinery, and military applications where reliability is critical.

Key Features:

1. Thread Specifications:

   • Metric thread (M5): 5mm nominal diameter with a standard pitch of 0.8mm (coarse thread).

   • Length: 10mm (measured from under the head to the end of the shank).

2. Head Design:

   • Typically a hex head (6mm or 8mm across flats) for standard wrench tightening.

   • Some variants have a clevis head (rounded with a hole) for easier wiring.

   • A pre-drilled hole (1-1.5mm diameter) in the head or shank allows safety wire to pass through.

3. Material & Finish:

   • Stainless steel (A2/AISI 304 or A4/316) for corrosion resistance.

   • Alloy steel (Grade 8.8, 10.9, or 12.9) with zinc plating or black oxide for high-strength applications.

   • May comply with military (MIL-SPEC) or aerospace (NAS, MS) standards.

4. Safety Wire Function:

   • The wire tension prevents rotation and loosening due to vibration.

Installation Notes:

• Wire should pull the bolt in the tightening direction if it begins to loosen.

• Paired with other safety-wired bolts for optimal security.
