Professional Applications & Engineering Value
This M4 flat head screw is engineered to solve common industrial challenges such as vibration loosening and material fatigue. Its zinc-plated alloy steel construction provides a robust barrier against corrosion, making it ideal for machinery, automotive assemblies, and outdoor equipment where environmental factors are a concern. The Class 10.9 high tensile strength and Rockwell C32 hardness ensure that the fastener maintains integrity under heavy loads and dynamic stresses. The flat head with a 90° countersink and hex drive design allows for a flush finish and secure torque application, preventing protrusions in tight spaces. Fully threaded with a coarse 0.7mm pitch and right-hand thread, it enables quick, reliable fastening in metals and composites, reducing assembly time while enhancing joint reliability in industrial applications.
Specification Summary & Compliance
This screw adheres to precise dimensional standards, including Class 6g thread fit per metric specifications and a length of 10 mm. It conforms to DIN 7991 and ISO 10642 for flat head hex drive screws, ensuring consistent quality and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting environmentally responsible and safe usage in various sectors.
