10.9 Grade Round Head Torx High Strength Bolt, Pan Head Internal Torx Locking Screw

Product Introduction

The 10.9 grade pan head torx bolt belongs to high tensile strength fasteners, specially developed for heavy-load vibration working conditions. Raw material is premium alloy steel, produced by integrated cold forging process to avoid structural fracture. The internal torx drive design provides larger torque transmission compared to cross slot and hex slot, effectively preventing tool slipping during high-torque installation. After precise quenching and tempering heat treatment, the bolt achieves stable 10.9 mechanical property grade, matched with blackening surface treatment to resist oxidation and rust.

Product Advantages

1. 10.9 High Strength Grade: High tensile and yield strength, suitable for heavy load connection.

2. Internal Torx Anti-Slip Head: Uniform force bearing, no head burst or sliding during tightening.

3. Alloy Steel Heat Treatment: Excellent anti-fatigue performance, stable locking under long vibration.

4. Black Oxide Surface: Low friction coefficient, good rust resistance for vehicle and machinery.

5. Full Customization: Custom thread diameter, total length and head thickness according to drawings.
