The anodized finish looks great and provides good corrosion resistance.

5 FAQ

Q: Are these screws rust-proof?

A: They are made of aluminum with an anodized finish, which offers good corrosion resistance but are not fully rust-proof like stainless steel.

Q: Do you offer bulk discounts for M8 sizes?

A: Yes, please contact our sales team directly for bulk pricing on larger quantities.

Q: Can I use these for high torque applications?

A: Aluminum is softer than steel. Please refer to torque specifications for aluminum fasteners to avoid stripping.

Q: What size hex key do I need for M5 screws?

A: For M5 socket head cap screws, you will typically need a 4mm hex key.

Q: Is the thread metric or imperial?

A: All screws in this listing are Metric thread standard.
