Product Description

The M3x30 hex bolts with External hex head M3, compliant with DIN 933 metric bolts standard, feature a 30 mm length, M3 thread diameter, and 5.5 mm hex head width. Designed for general industrial fastening in machinery, automotive, and electronics assembly, these bolts typically use carbon steel or stainless steel (grade A2/A4) with optional zinc plating for corrosion resistance. With a tensile strength of 8.8 grade (800 MPa) and thread pitch of 0.5 mm, they operate in temperatures ranging from -30°C to 120°C. Advantages include precise torque application via standard hex tools and broad compatibility, while limitations involve potential thread wear under extreme vibration. The full-thread design ensures uniform load distribution across connected components.
