Hexagon Head Shear Bolts are specialized fasteners designed to shear off at a predetermined torque, making them ideal for applications where over-tightening could damage components or where a specific breakaway force is desired. Here’s a detailed description:

Features:

1. Hexagon Head – Features a standard six-sided head for easy installation using a wrench or socket.

2. Shear Design – The shank is engineered with a weakened section (shear groove) that breaks off once the desired torque is reached, leaving a smooth, flush surface.

3. High-Strength Material – Typically made from hardened steel (grade 8.8, 10.9, or stainless steel) to ensure precise shearing under load.

4. スレッドタイプ – Available in coarse (UNC) or fine (UNF) threads, depending on application requirements.

5. 耐食性 – Often coated with zinc, galvanized, or other anti-rust treatments for durability in harsh environments.

6. Flange or Washer Option – Some variants include an integrated flange or washer to distribute load and prevent loosening.

アプリケーション

• Structural Engineering – Used in steel construction, bridges, and seismic bracing.

• Machinery & Automotive – Secures components that require controlled torque to prevent damage.

• Wind Turbines – Ensures bolts break away under extreme forces to protect critical parts.

• Military & Aerospace – Used in assemblies where precise failure points are critical.

利点がある：

• Prevents Over-Tightening – Shears off at a set torque, protecting sensitive components.

• Consistent Performance – Engineered to break at a precise load for reliability.

Common Sizes:

• Diameter: M6 to M24 (metric) or 1/4″ to 1″ (imperial).

• 長さ： Varies based on application (typically 20mm to 200mm).
