M6 M8 Stainless steel Flat & CSK Head Machine Metal Screw SUS304 SUS316 A2-70 A4 cross slot
A machine screw is a precision fastener designed for joining components in mechanical applications. These screws feature a diameter of 0.75 inches or less (as defined by ASME) with uniform threading that maintains consistent dimensions from top to bottom.
Applications
M3 screws: Owing to their compact dimensions and lightweight nature, M3 screws are frequently employed in small electronic devices, precision instruments, and applications requiring minimal installation space. Additionally, M3 screws are commonly used for joining thin sheet materials or as components within fine-adjustment mechanisms.
M4 Screws: Owing to their larger diameter and load-bearing capacity, M4 screws are better suited for connecting structural components subjected to heavier loads. For instance, they are frequently employed for fastening and joining in automotive manufacturing and mechanical equipment assembly.
