Triangular groove safety 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

A triangular slot safety bolt is a specialized fastener designed to provide enhanced security and tamper resistance. It features a unique triangular-shaped slot in the bolt head, requiring a matching triangular driver bit for installation and removal. This design helps prevent unauthorized access or tampering using standard tools like flathead or Phillips screwdrivers.

Key Features:

1. Triangular Slot Head – The bolt has a recessed triangular indentation, making it difficult to remove without the correct tool.

2. Tamper-Resistant – Unlike conventional bolts, it cannot be easily loosened with common tools, improving security.

3. Durable Material – Often made from hardened steel, stainless steel, or other robust materials for strength and corrosion resistance.

4. Applications – Used in high-security environments such as public infrastructure, electronics, machinery, and transportation systems where tampering must be prevented.

Advantages:

• Enhanced Security – Deters casual tampering and vandalism.

• Controlled Access – Only individuals with the correct triangular driver can remove the bolt.

• Wide Usage – Suitable for industries requiring secure fastening, including aerospace, automotive, and electronics.

Common Uses:

• Public fixtures (e.g., restroom partitions, street signs)

• Electronics enclosures (e.g., gaming machines, kiosks)

• Industrial machinery (e.g., safety guards, access panels)

Installation & Removal:

• Requires a triangular screwdriver bit or security bit set.

• Some versions may have additional security features like pin-in-center variants for even higher resistance.

This type of bolt is ideal for applications where standard fasteners may pose a security risk. Would you like details on suppliers or installation tips?
