Flat head shear bolts are specialized fasteners designed to break or “shear” at a specific torque or load, protecting machinery from damage by preventing overload. Here’s a detailed description:

Features of Flat Head Shear Bolts:

1. Head Design:

   • Flat Head (Countersunk): Allows the bolt to sit flush with the surface when installed, reducing protrusion and improving aerodynamics or safety in moving parts.

   • Shear Groove: A pre-weakened section (usually under the head or along the shank) ensures controlled breaking at a predetermined torque.

2. 材質：

   • Typically made from hardened steel, stainless steel, or other high-strength alloys to ensure consistent shear strength.

   • May have corrosion-resistant coatings (e.g., zinc plating) for durability.

   • Flat head shear bolt

3. Function:

   • Acts as a mechanical fuse, shearing off when excessive force is applied (e.g., in agricultural equipment, snowblowers, or conveyor systems).

   • Prevents costly damage to gears, shafts, or other components by failing first.

4. Thread Type:

   • Fully or partially threaded, depending on the application.

   • Thread pitch may be coarse or fine, matching the machinery’s requirements.

應用：

• Agricultural Machinery: Protects drivelines in tractors and harvesters.

• Snowblowers & Rotary Cutters: Shears when blades hit obstructions.

• Industrial Equipment: Used in gearboxes, couplings, and safety clutches.

Why Use Shear Bolts?

• Safety: Prevents catastrophic failure.

• Cost-Effective: Replacing a bolt is cheaper than repairing machinery.

• Precision: Engineered to shear at exact loads for consistent performance.

安裝提示：

• Always use the specified grade/size—improper bolts may not shear correctly.

• Tighten to the recommended torque; over-tightening can prematurely weaken the bolt.

• Flat head shear bolt

• Replace with identical shear bolts after failure—never substitute with standard bolts.
