Questions about this product

What are the exact dimensions of these M3 button head screws?
They're M3 screws with a standard 0.5 mm coarse thread pitch. The low-profile button head is about 5.5 mm wide and 2.0 mm high. You can choose lengths from 18 mm up to 50 mm depending on your project needs.
How strong is the 10.9 grade carbon steel used in these screws?
This carbon steel has a minimum tensile strength of 1040 MPa and a yield strength of 940 MPa. It rates between 32 and 39 HRC on the Rockwell hardness scale. This steel grade protects against shearing and deformation under heavy mechanical loads.
What tools do I need to install these screws without stripping them?
You will need a 1.5 mm hex socket key or Allen wrench to drive these M3 screws. The hex socket design allows you to apply high torque securely. Make sure your hex key is in good condition to prevent slipping during installation.
