Flat tail shear bolts are specialized fasteners designed to shear off at a predetermined torque or load, protecting machinery from damage by preventing overload. Here’s a detailed description:

主要功能：

1. Flat Tail Design

   • The bolt has a flat or slightly rounded end (as opposed to a pointed tip), making it suitable for applications where a smooth finish is needed after shearing.

   • The flat tail ensures the bolt sits flush or breaks cleanly without protruding.

   • 剪切螺栓平尾

2. Shear Groove (Weak Point)

   • Contains a pre-machined notch or groove near the head or along the shank, which is the weakest point.

   • This ensures the bolt breaks predictably under excessive force, protecting sensitive components.

3. Material & Strength

   • Typically made from medium-carbon steel, stainless steel, or alloy steel for durability.

   • Heat-treated to precise hardness levels to ensure consistent shear strength.

4. 頭部類型

   • Common heads include hex, flange, or countersunk to fit different applications.

   • Some have a smooth, rounded head to minimize damage if the bolt shears.

5. 線路類型

   • Fully or partially threaded, depending on the application (e.g., securing shear plates in agricultural or industrial equipment).

常見應用：

• Agricultural Equipment (e.g., mowers, tillers, balers)

• 工業機械 (e.g., conveyor systems, gearboxes)

• 汽車與航太 (safety-critical shear points)

• Construction Equipment (shear pins in augers, crushers)

Shear Bolt vs. Standard Bolt:

• 剪切螺栓 are engineered to fail at a specific torque, acting as a mechanical fuse.
