FAQ
Standard or thin square nut?
Standard (DIN 557) nuts have more threads for full strength. Thin (DIN 562) nuts fit tight slots and shallow channels.
What does M8 x 1.25 mean?
M8 is the thread diameter in millimeters and 1.25 is the thread pitch, the distance in millimeters from one thread to the next. Standard (coarse) pitch is the most common; fine pitch has the threads closer together.
