螺栓、螺絲、螺帽、鉚釘和銷等緊固件

A triangular raised safety bolt is a specialized fastener designed to provide enhanced security by deterring tampering or unauthorized removal. Here are its key characteristics:

功能：

1. Triangular Head Design:

   • The bolt has a three-lobed (triangular) raised head, requiring a matching triangular socket or driver for installation/removal.

   • Unlike standard hexagonal or Phillips heads, this shape makes it difficult to grip with common tools like wrenches or pliers.

2. Raised or Domed Profile:

   • The head is slightly raised or domed, preventing easy access to the edges with prying tools.

   • The smooth, curved surface makes it hard to grip with locking pliers or vice grips.

3. 防拆:

   • The uncommon shape acts as a deterrent against casual tampering.

   • Often used in public fixtures, security panels, or high-theft-risk applications.

4. Material & Finish:

   • 通常由 hardened steel, stainless steel, or brass for durability.

   • May have corrosion-resistant coatings (e.g., zinc plating, black oxide) for outdoor use.

5. 線路類型:

   • 可用於 machine thread (bolts) 或 self-tapping thread (screws) depending on application.

常見用途：

• Security panels & enclosures

• 三角形凸起安全栓

• Public infrastructure (e.g., restroom fixtures, signage)

• Electronics & machinery requiring restricted access

• Transportation (e.g., license plates, rail components)
