Safety wire bolt with middle hole

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

A Safety Wire Bolt with Center Hole is a specialized fastener designed to secure critical components in high-vibration or high-stress environments, preventing loosening due to dynamic forces. It features a drilled axial hole through the center of the bolt head or shank, allowing safety wire (lock wire) to be threaded through it and secured to another component or adjacent bolt.

Key Features:

1. Central Axial Hole – A precision-drilled hole running through the length of the bolt head or along the shank to accommodate safety wire.

2. Material – Typically made from high-strength steel, stainless steel, or titanium for corrosion resistance and durability.

3. Thread Type – Available in various thread standards (metric, UNC, UNF, etc.) depending on application.

4. Head Style – Commonly hex head, but may also be socket head, pan head, or other configurations.

5. Wire Retention – The hole allows the safety wire to loop through, ensuring the bolt cannot rotate loose under vibration.

6. Safety wire bolt with middle hole

Applications:

• Aerospace – Securing aircraft engine components, landing gear, and control surfaces.

• Motorsports – Used in race cars and motorcycles to prevent critical fasteners from backing out.

• Military & Defense – Ensures reliability in weapon systems and armored vehicles.

• Industrial Machinery – Prevents bolt loosening in high-vibration equipment like turbines and compressors.

Advantages:

• Positive Locking – Prevents rotation and loosening even under extreme conditions.

• Tamper-Resistant – Requires wire cutters for removal, enhancing security.

• Redundancy – Even if one fastener fails, the wired connection maintains safety.

• Safety wire bolt with middle hole

Installation Method:

1. Insert the bolt and tighten to the specified torque.

2. Thread safety wire through the center hole.

3. Loop and twist the wire to an adjacent bolt or fixed structure, ensuring tension prevents rotation.

This bolt type is essential in industries where mechanical failure due to vibration is unacceptable, providing a reliable, mechanical locking solution.
