FAQs about A2 stainless steel socket cap head screws

What material is this socket cap head screw made from?

This screw is made from A2 stainless steel, which gives a high corrosion resistance making it ideal for both internal and external environments.

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.

What does DIN 912 mean on a socket cap head screw?

DIN 912 is the industrial standard defining the dimensions, tolerances, and internal hex drive specifications for socket cap head screws, ensuring consistent fit and reliability across applications.

Can A2 stainless steel socket cap screws be used outdoors?

Yes, A2 stainless steel has high corrosion resistance, making this screw suitable for long term outdoor use.

What is the difference between A2 and A4 stainless screws?

A2 stainless steel offers a high corrosion resistance making it ideal for long term external use. The A4 stainless steel offers a higher marine grade corrosion resistance, which also makes it ideal for external use including salt water and marine environments.

Are socket cap head screws strong enough for precision engineering?

Yes, socket cap head screws are widely used in precision engineering applications due to their ability to be tightened with high torque in tight spaces, along with metric sizing which ensures accurate installation.
