FAQs about self-colour cap head socket screws

What does “Grade 12.9” mean with socket cap head screw?

Grade 12.9 refers to a high-tensile steel strength class. It means the screw has an ultimate tensile strength of 1200 MPa (or approximately 175,000 psi) making it one of the strongest metric fasteners available.

Grade 12.9 is typically used in engineering, automotive, machinery and heavy-duty applications where maximum strength is required.

What is a “self-colour” finish?

“Self-colour” means the screw is supplied in its natural steel finish after heat treatment. The screws are sometimes lightly oiled or treated with a black oxide.

Are grade 12.9 socket cap screws corrosion-resistant?

No, these cap head screws are not corrosion resistant and the self-colour or black oxide finish gives limited resistance, making them not suitable for external conditions.

How is the length of the cap head screw measured?

The length of these screws is measured from under the head to the end of the thread, not including the head height.

Can I use grade 12.9 screws in high-temperature or vibrating applications?

Yes, these grade 12.9 screws are suitable for high operating temperatures and perform well in vibration-prone environments such as engines or machinery where they are widely used.
