M1.2 is a metric screw thread size, and M1.2 screws, bolts, nuts, and washers are commonly used in a variety of applications. M1.2 screws have a 1.2-millimetre diameter and a thread pitch of 0.35 millimetres. They are made of plastic or polymer materials and are typically used in applications where a lightweight and corrosion-resistant fastener is needed. They are commonly used in electronic devices, automotive components, and other applications where metal screws may be too heavy or prone to corrosion. M1.2 nuts and washers are used to secure M1.2 screws and bolts in place. Washers are flat rings that are used to distribute the load of a fastener and to prevent damage to surfaces. Nuts are used to fasten bolts and screws together and are typically tightened using a wrench.
