不銹鋼 shear bolts are specialized fasteners designed to break or “shear” at a predetermined torque or load, providing a controlled failure point in mechanical systems. Here’s a detailed description:
1. Material
-
Made from 不銹鋼 (typically grades like 304 or 316 for corrosion resistance).
-
Offers high strength while resisting rust, chemicals, and extreme temperatures.
2. Design & Function
-
剪切功能: The bolt is engineered to snap at a specific shear load, protecting critical components from over-torque or mechanical failure.
-
Head Design: Often features a breakaway head (e.g., hex, countersunk) that shears off once the desired torque is reached, leaving a smooth surface.
-
Shank: May have a weakened section (necked down) to ensure consistent shear performance.
3. Applications
-
用於 aerospace, automotive, marine, and structural engineering where controlled failure is necessary.
-
常見於 safety systems, shear pins, and tamper-proof assemblies.
- Stainless Steel Shear Bolts
4. Advantages
-
耐腐蝕性: Ideal for harsh environments (saltwater, chemicals).
-
Precision Shearing: Ensures reliability in critical applications.
5. Standards & Specifications
-
符合 ASTM, ISO, or DIN standards depending on application.
-
Available in various diameters, lengths, and shear strengths.
6. Installation
-
Requires calibrated tools to ensure proper torque/shear point.
-
Often used with locking nuts or washers for security.
