Flachkopf-Abreißschraube

Das Kaltstauchverfahren ist eines der neuen Verfahren für die Druckbearbeitung mit weniger oder gar keiner Zerspanung
Metall. Es handelt sich um eine Verarbeitungsmethode, die die plastische Verformung von Metall unter der Einwirkung von
äußere Kräfte, und mit Hilfe von Formen wird das Metallvolumen umverteilt und in die Form gebracht
die gewünschten Teile oder Rohlinge. Das Kaltstauchverfahren ist am besten geeignet für die Herstellung von Standard
Verbindungselemente wie Bolzen, Schrauben, Muttern, Nieten, Stifte usw.

Flat head Scherbolzen 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. Material:

   • 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.

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. Gewindetyp:

   • Fully or partially threaded, depending on the application.

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

Anwendungen:

• 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.

• Kostengünstig: Replacing a bolt is cheaper than repairing machinery.

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

Tipps zum Einbau:

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

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

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