Good quality, fast shipping

Ordered the M4 size for an electronics enclosure. They fit perfectly and the internal drive prevents stripping better than Phillips. One star off because the box was slightly dented, but the screws were fine.

True to GB2672 standard

As a mechanical engineer, I appreciate that these actually meet the national standard specifications. The head dimensions are precise, and the torque resistance is excellent for Grade 8.8.

Perfect for security applications

These Torx screws are exactly what I needed for a project requiring anti-theft features. The grade 8.8 strength is solid, and the galvanization looks uniform without any rust spots.

Eco-friendly coating is a plus

Happy to find galvanized screws that use an eco-friendly process. They look great and seem very durable. Will definitely reorder the M6 size soon.

Solid hardware

Very strong screws. The pan head sits flush nicely. Just make sure you have the correct security bit driver, as standard Torx won't fit the center pin.

Great value for bulk purchase

Bought a mixed kit for our workshop. The variety of sizes from M2 to M8 covers most of our daily needs. Quality is consistent across all sizes.

5 FAQ

Q: Are the threads metric or imperial?

A: All screws listed in this product line follow the Metric system (M2 through M8) as per the GB2672 national standard.

Q: Can I return unopened boxes if I ordered the wrong size?

A: Yes, unopened original packaging can be returned within 30 days of delivery for a full refund, provided the items are in resalable condition.

Q: What is the tensile strength of Grade 8.8 in this context?

A: Grade 8.8 indicates a minimum tensile strength of 800 MPa and a yield strength ratio of 0.8, making them high-tensile fasteners suitable for structural applications.

Q: Do these screws come with the matching security driver bit?

A: No, the screws are sold separately. You will need to purchase a compatible Security Torx (Tamper-Resistant) bit set separately to install them.

Q: Is the galvanization suitable for outdoor use?

A: The eco-friendly galvanized coating provides good corrosion resistance for indoor and mild outdoor environments. For harsh marine or chemical environments, we recommend stainless steel alternatives.
