M10*28mm 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 M10×28mm 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 Size (M10):

   • Metric coarse thread with a 10mm nominal diameter (standard pitch: 1.5mm unless specified otherwise).

   • Compatible with M10 nuts or threaded holes.

2. Length (28mm):

   • 28mm shank length (measured from under the head to the end of the bolt).

   • May include threaded vs. unthreaded portion specifics depending on design.

   • M10*28mm Safety Wire Bolt

3. Head Type:

   • Typically has a hex head (e.g., 6mm hex wrench size) or another style (e.g., flange head) for tool engagement.

   • Features pre-drilled holes (usually two) in the head or shank for safety wire passage.

4. 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 durability.

5. Safety Wire Function:

   • The drilled holes allow locking wire (0.8–1.2mm stainless steel wire) to be threaded through adjacent bolts, securing them against rotation.

   • Used in aerospace, automotive, and machinery to prevent loosening under vibration.

Common Standards:

• ISO 7380 or MS/MIL-SPEC (e.g., MS21250) for aerospace applications.

• DIN 916 for metric safety wire bolts.

Typical Applications:

• Aircraft engines, motorcycles, racing vehicles, and industrial equipment exposed to high vibration.

Note:

• Confirm hole alignment (radial or axial) and wire gauge compatibility for your specific use case.
