Alloy Steel Torx Drive Cup Head Bolt Torx Socket Head Cap Screw

描述

1.Superior Mechanical Performance
Forged from quenched-and-tempered alloy steel (grade 10.9，grade12.9), these Torx-socket cap screws deliver tensile strengths ≥1 040 MPa and yield strengths ≥940 MPa, with a core hardness of HRC 36–42. A precision black-oxide (or optional zinc) finish (≥8 µm) gives moderate corrosion resistance while maintaining smooth thread engagement.

2.Broad Application Versatility
Ideal for high-tension fastening in machine tools, automotive assemblies, robotics, electronics enclosures, medical devices, and structural fixtures. Available in ISO-metric threads (M3–M12) and lengths from 6–80 mm, they fit a wide range of tapped holes, threaded inserts, and mating components.

3.Precision Torx Drive for Effortless Operation
The recessed Torx head (T10–T40) ensures self-centering engagement and high torque transfer (up to 25 Nm) with virtually no cam-out. Quick insertion and removal with standard Torx bits minimize operator fatigue and protect screw head geometry even under repeated service.

4.Certified Quality & Long-Lasting Reliability
Produced in ISO 9001–certified facilities to tolerances across standards (±0.1 mm), each batch undergoes dimensional inspection, hardness testing, and ≥96 h salt-spray resistance per ASTM B117. Full material traceability and RoHS compliance guarantee consistent, long-term performance in demanding environments.
